Replacement Battery for ThinkPad R60 R61 T60 T61

This 7800 mAh lithium-ion pack is built for owners of Lenovo ThinkPad R60, R61, T60, T61, Z60 and T500 models who need a new power source. It matches the original 10.8V specification and restores mobile runtime without modification. The cell chemistry is lithium-ion, consistent with the factory design.

Fits Directly Into Compatible ThinkPad Chassis

The battery slides into the standard bay on the listed ThinkPad models, requiring no adapter, cable or firmware change. It uses the existing latch and connector, freeing the user from carrying an external power bank or staying tethered to an AC adapter. No additional hardware is needed for installation.

Lithium-Ion Chemistry Runs Cool Under Normal Loads

Lithium-ion cells generate minimal heat during typical office or web workloads, keeping the palm-rest area comfortable. The pack draws power only when the system requests it, so idle drain stays low and fan activity is not increased. Normal charging cycles complete within the laptop’s standard power-management routine.

Questions about this item

How long does the 7800 mAh capacity last before the battery needs recharging under heavy load?

The 7800 mAh lithium-ion cell stores more energy than lower-capacity packs, so run-time under sustained load is extended, though exact hours depend on the ThinkPad model and workload.

Does the 10.8 V lithium-ion pack run hot or make noise during all-day use?

Lithium-ion batteries operate silently and generate only modest warmth; the 10.8 V pack is designed to stay within normal thermal limits for the R60, R61, T60, T61, Z60 and T500 chassis.

Which ThinkPad models must I already own for the 40Y6797-TM to fit and work?

This battery is built for Lenovo ThinkPad R60, R61, T60, T61, Z60 and T500 systems; it will not fit other models.
