Direct replacement for ThinkPad 33+ batteries

The NShi GHU-T61 is a new 6-cell lithium-polymer pack rated at 48 Wh and 10.8 V. It matches the original 33+ form factor for 14.1-inch widescreen ThinkPad models including the T61, T61p, R61, R61i, R400 and T400 series.

Fits existing bays without modification

The battery slides into the standard ThinkPad battery compartment and connects to the same motherboard header used by part numbers such as 42T4531, 43R2499 and 41U3198. No extra cabling, adapters or firmware updates are required, leaving the AC adapter port and internal drive bays untouched.

Replaces worn 4400 mAh packs in older 14-inch

When the original 4400 mAh cell group no longer holds a useful charge, this 48 Wh unit restores full mobile runtime. The upgrade is worthwhile for machines still used daily on battery power; users needing higher capacity than 48 Wh or a different voltage should look elsewhere.

Questions about this item

How long will the 48 Wh capacity last before the voltage drops under continuous load?

The 48 Wh rating at 10.8 V gives roughly 4 400 mAh, so runtime depends on the notebook's power draw rather than a fixed voltage limit.

Does the lithium-polymer pack run hot or make noise during all-day use?

Lithium-polymer cells have no moving parts and generate minimal heat under normal charging and discharging cycles.

Which ThinkPad models must I already own for this 6-cell battery to fit?

It fits 14.1-inch widescreen ThinkPad T61, T61p, R61, R61i, R400 and T400 machines that originally used part numbers such as 42T5263 or 42T4531.
