Compatible replacement battery
The NShi GHU-PA5157U is a new lithium-polymer battery built to replace the original PA5157U-1BRS pack in a range of Toshiba Satellite laptops. It fits 15.6 inch models including the U940, E45T and E55 series. The pack delivers 11.1V and 50Wh from Grade A cells with an integrated smart control chip.
Lithium-polymer chemistry limits
Lithium-polymer cells cannot be charged below freezing and should not be stored at full charge for long periods. The built-in IC manages charge current and protects against over-discharge, but the chemistry still ages with every cycle. Expect up to 500 charge and discharge cycles before capacity drops noticeably.
Capacity and runtime headroom
At 50Wh the pack supplies enough energy for several hours of typical office work on a 15.6 inch Satellite. Heavy loads such as sustained video playback or gaming will drain it faster and reduce the effective runtime. Users who need all-day autonomy away from mains power will find the capacity limiting.

Questions about this item
Which capacity should I choose for a Toshiba Satellite E45T-A4100?
The GHU-PA5157U delivers 50 Wh at 11.1 V, matching the original PA5157U-1BRS specification for the E45T-A4100 and the wider E45T, E55 and U940 series.
What does the 50 Wh rating mean for daily use on my E55T-A5320?
A 50 Wh pack typically powers a 15.6" Satellite for several hours of mixed workloads; the built-in smart IC manages charge cycles to maintain that runtime across up to 500 cycles.
Does this battery use the same connector and voltage as the original PA5157U?
Yes — it is an 11.1 V lithium-polymer unit with the identical PA5157U-1BRS / P000577250 part numbers, so it fits the Satellite U940, E45T and E55 families without adapters.
