The best Tripp Lite UPS replacement battery is the one that matches your exact model, battery count and terminal type. The G1010USB pick is a single 12V battery, while several SMART1500 models use two-battery sets and rack systems may need complete cartridges.

We compared the stated compatibility and battery details for nine options. Use the model number on the UPS label, not just its product family name, because SMART1500LCD and SMART1500LCDT are distinct models in these picks.

How we chose Tripp Lite UPS replacement batteries

Compatibility and assembly details matter most when selecting a Tripp Lite UPS battery. We checked the named models, voltage, capacity, terminals, included parts and warranty terms for each option.

A cartridge with connectors and an enclosure can save assembly steps when it matches your UPS. A battery-only pack can cost less effort to source, but it requires the correct terminal, wiring and dimensions to match the existing setup.

Scores weigh specs, features and buyer feedback against what you're shopping for.

Compare Tripp Lite replacement batteries by model

Use the comparison table to narrow the list, then verify the complete model code and battery assembly. The same UPS family can have different terminals or cartridge layouts.

Best replacement batteries for Tripp Lite UPS systems

The top picks cover different UPS models, so choose by compatibility before comparing battery capacity. A higher amp-hour figure alone does not make a battery suitable for your UPS.

Mighty Max Battery 12V 7.2AH SLA Replacement: Best for G1010USB

9.7/10Our score

• 12V 7.2Ah sealed lead acid
• F1 terminal
• 5.90 x 2.50 x 3.90 in
• Battery only

This single battery is identified for the Tripp Lite G1010USB UPS. Check the existing battery count, terminal and compartment before ordering.

See it on Amazon

Pros

• G1010USB-specific title
• Dimensions and terminal type are stated
• One-year warranty

Cons

• Battery only, with no wire harness or mounting accessories
• Confirm whether your UPS takes one battery

Mighty Max's 12V 7.2Ah battery is the clearest match for a Tripp Lite G1010USB in this group. Its F1 terminal and 5.90 x 2.50 x 3.90 in dimensions give you concrete details to compare with the battery already installed.

This is a battery-only replacement. The package does not include a wire harness or mounting accessories, so check whether your UPS uses a separate harness and whether the existing parts are in good condition.

The battery is sealed lead acid and rechargeable. Mighty Max provides a one-year warranty, and the battery can be mounted in any position according to its stated features.

Choose it when the UPS label says G1010USB and the original battery's terminal and dimensions match. Don't assume that the 12V rating alone confirms a fit.

Best for the G1010USB when you need one 12V 7.2Ah battery and can reuse the correct wiring and mounting parts.

Mighty Max Battery 12V 8AH SLA Replacement: Best for SMART1500LCD two-battery swaps

9.6/10Our score

• Two 12V 8Ah sealed lead acid batteries
• F1 terminals
• 5.94 x 2.56 x 4.02 in per battery
• Battery only

The two-battery pack is named for the SMART1500LCD and gives dimensions and F1 terminals for each battery. Confirm the exact battery configuration in your unit.

See it on Amazon

Pros

• Two batteries in one pack
• SMART1500LCD named in the product title
• One-year warranty

Cons

• No wire harness or mounting accessories
• F1 terminal fit needs checking

This Mighty Max pack includes two 12V 8Ah batteries, and the product is named for the Tripp Lite SMART1500LCD. Each battery measures 5.94 x 2.56 x 4.02 in and uses an F1 terminal.

The two-battery format can suit a UPS whose original pack uses a matched pair. Confirm the terminals carefully, since another SMART1500LCD replacement in this roundup uses F2 terminals.

The batteries are sealed lead acid and rechargeable. Mighty Max states a one-year warranty, but no wire harness or mounting accessories are included.

Choose this set if your SMART1500LCD has two F1-terminal batteries with matching dimensions. If your original set uses F2 terminals, compare the UPS Battery Center or Origin Battery options instead.

Best for SMART1500LCD owners with F1 terminals who need a two-battery set.

3

RBC94-2U-UPC Replacement Battery for Tripp Lite SMART1500RMXL2U: Best for compatible rack UPS models

9.4/10Our score

• Two 12V 9Ah batteries
• Connectors, cable, fuses and enclosure included
• Pre-charged
• Hot-swappable compatible

A complete RBC94-2U-UPC assembly is specified for several Tripp Lite rack models. Match the full model number and suffix before selecting it.

See it on Amazon

Pros

• Several compatible models named
• Assembly includes connectors and cable
• Pre-charged and hot-swappable compatible

Cons

• Heavy assembly at about 23 lb
• Model compatibility must match

The RBC94-2U-UPC is a complete assembly for several named Tripp Lite rack models, including SMART1500RMXL2U, T2200RMXL2U, SMART3000RM2U and SMX3000XLRT2U. It includes two 12V 9Ah batteries, connectors, cable, fuses and a metal enclosure.

The assembly arrives pre-charged and is described as plug-and-play and hot-swappable compatible. Its stated weight is about 23 lb, so plan for a substantial cartridge when handling or installing it.

UPC gives this battery assembly an 18-month warranty. The description also names other compatible models, but the complete suffix matters, so compare it against your UPS label and old cartridge.

This option is for rack units that use the RBC94-2U format. It is not a loose replacement for a desktop UPS that takes individual batteries.

Best for compatible rack UPS models when you need the battery assembly, connectors and enclosure together.

4

UPS Battery Center SMART1500LCD: Best for SMART1500LCD F2 terminals

9.2/10Our score

• Two 12V 7.2Ah sealed lead acid batteries
• F2 terminals
• Fully charged
• One-year replacement warranty

This assembled replacement set is identified for the SMART1500LCD. Its F2 terminals and two-battery configuration make it important to compare against the original set.

See it on Amazon

Pros

• SMART1500LCD compatibility stated
• Two batteries with F2 terminals
• Arrives charged

Cons

• Not identified for the SMART1500LCDT
• Verify terminal and model before ordering

UPS Battery Center identifies this set for the Tripp Lite SMART1500LCD. It contains two 12V 7.2Ah sealed lead acid batteries with F2 terminals and arrives charged.

Its most useful distinction is the F2 terminal specification. Compare it with the old batteries rather than relying on the SMART1500LCD name alone, especially if you are choosing between replacement sets with different terminal types.

The set measures 5.94 x 2.56 x 3.7 in as a pack. UPS Battery Center includes a one-year replacement warranty.

This option is for the SMART1500LCD, not the similar SMART1500LCDT model called out by a separate set below. Confirm the full model code before you buy.

Best for SMART1500LCD owners who need F2 terminals and a 7.2Ah two-battery set.

5

Tripp Lite Certified Replacement Battery Cartridge: Best for SMART500RT1U

9.0/10Our score

• RBC62-1U cartridge
• Pre-assembled pair of 6V batteries
• 12V output
• 18-month warranty

This Tripp Lite cartridge is specified for SMART500RT1U and SMX500RT1U systems. Confirm the RBC62-1U cartridge code against the UPS.

See it on Amazon

Pros

• Tripp Lite-branded cartridge
• Specific compatible models named
• Pre-assembled pack

Cons

• Only for the stated cartridge family
• Not a general-purpose bare battery

Tripp Lite's RBC62-1U cartridge is specified for the SMART500RT1U and SMX500RT1U. It arrives as a pre-assembled pack of two 6V batteries, for a 12V total.

A cartridge format can simplify replacement because the two batteries are already arranged as a pack. The model number is the key check: RBC62-1U is a different cartridge family from the RBC93-2U used by larger rack models.

Tripp Lite says its certified replacement cartridges are screened to meet or exceed original specifications and ship ready for installation. This cartridge has an 18-month warranty.

Choose it only if your UPS calls for RBC62-1U or one of the stated compatible models. For another UPS model, check Tripp Lite's battery cross-reference before ordering.

Best for SMART500RT1U and SMX500RT1U owners who need a pre-assembled cartridge.

6

UPS Battery Center: Best for SMART1500LCDT

8.7/10Our score

• Two 12V 7Ah sealed lead acid batteries
• F2 terminals
• Assembled and charged
• One-year replacement warranty

This assembled set is identified for the SMART1500LCDT. Keep the final T in the model number in mind, since similar model names can use different battery sets.

See it on Amazon

Pros

• SMART1500LCDT compatibility stated
• Two batteries assembled and charged
• F2 terminals

Cons

• Not specified for SMART1500LCD
• Capacity differs from the other SMART1500LCD set

This UPS Battery Center pack is identified for the Tripp Lite SMART1500LCDT, with a final T in the model name. It includes two 12V 7Ah sealed lead acid batteries, assembled and charged, with F2 terminals.

The distinction between SMART1500LCD and SMART1500LCDT matters here. The similar model names do not mean the batteries are interchangeable, so read the UPS label and compare the original pack before selecting this option.

UPS Battery Center includes a one-year replacement warranty. The product's stated battery capacity is 7Ah per battery, which differs from the 7.2Ah and 9Ah SMART1500LCD sets in this roundup.

Choose it for the LCDT model when the original set matches the stated two-battery F2 configuration. Don't select it solely because your UPS name begins with SMART1500LCD.

Best for SMART1500LCDT owners who need an assembled two-battery F2 set.

7

PowerStar--Tripp Lite RBC51 UPS Battery -Replacement HIGH: Best for matching 12V 9Ah batteries

8.5/10Our score

• 12V 9Ah sealed lead acid
• T2 terminals
• 5.28 x 2.64 x 2.62 in stated dimensions
• Maintenance-free AGM design

This is a single 12V 9Ah battery with T2 terminals. Compare its measurements and terminal type with the removed battery, and confirm the UPS model accepts this format.

See it on Amazon

Pros

• Capacity and terminal type stated
• Dimensions provided
• Single replacement battery

Cons

• No specific Tripp Lite UPS model compatibility stated
• T2 terminal fit must match

PowerStar's RBC51 is a single 12V 9Ah sealed lead acid battery with T2 terminals. Its stated dimensions are 5.28 x 2.64 x 2.62 in, so compare those measurements with the battery compartment and the old battery.

The product data doesn't name a specific Tripp Lite UPS model as compatible. Treat this as a general battery option that needs a careful fit check, not as a complete cartridge replacement.

The AGM design is described as leak-free and maintenance-free. The product title mentions a three-year warranty, but warranty terms can depend on the seller and purchase, so confirm the current coverage before relying on it.

Choose this battery only when your UPS manual allows a single 12V 9Ah battery with matching dimensions and T2 terminals. A similar capacity or voltage is not enough by itself.

Best for buyers matching a 12V 9Ah T2 battery to an existing UPS setup.

8

Tripp Lite Certified Replacement Battery Cartridge: Best for SMART1500RM2U

8.3/10Our score

• RBC93-2U cartridge
• Three 12V batteries in pre-assembled pack
• Metal enclosure
• 18-month warranty

The RBC93-2U cartridge is specified for several 2U rack models, including the SMART1500RMXL2UA suffix version. Check the complete model code before choosing it.

See it on Amazon

Pros

• Tripp Lite-branded cartridge
• Named rack model compatibility
• Pre-assembled battery pack

Cons

• Model suffix matters
• Designed as a cartridge, not a loose battery

Tripp Lite's RBC93-2U cartridge is specified for SMART1500RM2U, SMX1500RM2U and SMART1500RMXL2UA. The model suffix matters: the stated compatibility is for the SMART1500RMXL2UA version.

This rack cartridge contains three 12V batteries in a pre-assembled pack and has a metal enclosure. Its form and battery count make it a different choice from a two-battery SMART1500RMXL2U assembly.

Tripp Lite says its replacement cartridges ship ready for installation and can be returned in reusable packaging for battery recycling. The stated warranty is 18 months.

Confirm the exact UPS model and cartridge code before purchase. If your old cartridge is RBC94-2U, this RBC93-2U is not a substitute based on the similar model numbers.

Best for SMART1500RM2U and other listed models when the UPS specifically uses RBC93-2U.

9

Origin Battery Tripp-Lite SMART1500LCD Battery Replacement Kit: Best for SMART1500LCD 9Ah capacity

8.0/10Our score

• Two 12V 9Ah sealed lead acid batteries
• F2 terminals
• 5.94 x 2.56 x 4.06 in per battery
• Two-year warranty

This kit is described for the SMART1500LCD and includes two 12V 9Ah batteries with F2 terminals. Compare its dimensions and capacity with your original pack.

See it on Amazon

Pros

• SMART1500LCD named
• Two batteries included
• Two-year warranty

Cons

• Confirm the UPS label and original battery configuration
• Kit requires a fit check before ordering

Origin Battery's kit is described for the Tripp-Lite SMART1500LCD and includes two 12V 9Ah sealed lead acid batteries. Each battery has an F2 terminal and measures 5.94 x 2.56 x 4.06 in.

The 9Ah capacity differs from the 7.2Ah UPS Battery Center set and 8Ah Mighty Max pair. Match the battery size, terminals and original configuration, and follow the UPS maker's replacement guidance.

Origin Battery states a two-year warranty. Its kit is described as using AGM HR series batteries, but confirm fit and warranty coverage with the seller if any detail differs from your original pack.

This is a model-specific option for SMART1500LCD owners who want a 9Ah pair with F2 terminals. It is not the same set as the SMART1500LCDT pack above.

Best for SMART1500LCD owners seeking a 9Ah F2 pair with a stated two-year warranty.

What should you check before buying a Tripp Lite UPS battery?

Check the full UPS model, cartridge code, battery count, voltage, capacity, terminal type and dimensions before ordering. Those details prevent a common mismatch: choosing a battery that shares the voltage but uses the wrong connector or pack arrangement.

If your UPS uses a complete cartridge, compare the cartridge code printed on the old pack or in the manual. RBC62-1U, RBC93-2U and RBC94-2U refer to different assemblies.

For loose batteries, compare each battery's measurements and terminals, then confirm whether the UPS uses one battery or a matched pair. Also check whether you need to reuse a harness or mounting parts.

Can a replacement battery change UPS runtime or switching?

A replacement battery restores backup only when it matches the UPS and is in good condition. Runtime still depends on the connected load and the UPS design, so a higher amp-hour rating alone doesn't promise a specific backup time.

The battery also doesn't change how quickly the UPS switches to battery power. Our guide to how fast a UPS switches to battery power explains transfer time, while what a hybrid UPS system is covers a different UPS design question.

If you're comparing replaceable battery systems beyond Tripp Lite, see our guides to the best CyberPower UPS replacement battery, UPS systems with replaceable batteries and CyberPower CP1500PFCLCD battery replacement.

Which Tripp Lite replacement battery should you choose?

Choose by the full UPS model and battery assembly first, then compare capacity and warranty. For a G1010USB, start with the Mighty Max single battery; for SMART1500LCD or LCDT units, verify the terminal and suffix; for rack systems, match the RBC cartridge code.

The best tripp lite ups replacement battery is the one that matches the original voltage, battery count, terminals and dimensions. If those details don't line up, check the UPS manual or Tripp Lite support before ordering.

Frequently asked questions

How do I find the right replacement battery for a Tripp Lite UPS?

Read the full UPS model number from its label, then check the battery cartridge code or the voltage, capacity, terminal type and battery count inside the unit. Similar model names can use different packs.

Match the replacement to the exact model and assembly before buying.

Can I replace a Tripp Lite UPS cartridge with loose batteries?

Sometimes, but only if the replacement batteries match the original voltage, capacity, dimensions, terminals and wiring arrangement. A cartridge may include connectors, fuses, cables or an enclosure that loose batteries do not.

Use a complete compatible cartridge when you cannot safely reproduce the original assembly.

Can I use LiFePO4 batteries in a Tripp Lite UPS?

Only if Tripp Lite approves that battery chemistry for your exact UPS model. These picks are sealed lead acid replacements, and charging controls designed for lead acid may not suit LiFePO4.

See our guide on whether you can use LiFePO4 batteries in a UPS before considering a different chemistry.

Does a new UPS battery restore the original runtime?

A compatible fresh battery can restore battery backup, but runtime depends on the UPS model, battery condition and connected load. It won't make a UPS provide more capacity than its design allows.

Check the UPS manual for the battery replacement and charging guidance.

Should I replace both batteries in a two-battery UPS?

If the UPS uses a matched pair, replace both with the same type and capacity unless the manufacturer says otherwise. Mixing an older battery with a new one can leave the pair uneven.

Check the original assembly and follow Tripp Lite's service instructions.
