9-Cell 11.1V 94Wh replacement battery

This 9-cell lithium-ion pack delivers 11.1 volts and 94 watt-hours of capacity. It is built as a direct replacement for a wide range of Lenovo ThinkPad models across the L, T, W, SL and Edge series. The unit matches the original 8.4 ampere-hour rating and fits the existing battery bay without modification.

Sustained output and protection

The lithium-ion chemistry maintains a stable voltage curve through extended workloads rather than dropping off after a short burst. Integrated safeguards include short-circuit, over-voltage, over-current and discharge protection to preserve both the pack and the notebook during long sessions. The 9-cell layout distributes load across more cells, reducing per-cell stress under continuous draw.

Upgrade from lower-capacity packs

This battery replaces 6-cell or lower-capacity units that shipped with many supported ThinkPads, adding roughly 50 percent more watt-hours for longer unplugged runtime. The jump is worthwhile for users who regularly work away from mains power on the listed T410 through T530, W510 through W530, L410 through L530 and Edge 14 or 15 models. It is not suited for newer ThinkPad generations that use a different form factor or connector.

Questions about this item

Does the 9-cell 94Wh battery run hotter than the original 6-cell during all-day use?

The 11.1V Li-ion pack uses the same voltage as the factory unit, so thermal output stays comparable; the larger 8.4Ah capacity simply extends runtime.

My ThinkPad T430 uses part number 45N1001 — will this battery fit without any extra cabling?

Yes, 45N1001 is listed among the compatible FRU part numbers, so the battery connects directly to the existing laptop connector.

Can I keep my older 6-cell charger (42T4751) when switching to this 9-cell 94Wh pack?

The charger part 42T4751 appears in the compatible ASM list, so the original power brick will charge the higher-capacity battery normally.
