Replacement Battery for Asus Transformer Book Flip
This 11.4 V 39 Wh lithium-polymer battery replaces the original B31N1345 pack in Asus Transformer Book Flip TP500LA, TP500L, TP500LN and TP500LB models. It is built for owners who need to restore full mobile runtime on those specific convertible notebooks. Buyers with other Asus lines or non-Transformer Book Flip chassis cannot use this unit.
Straightforward Internal Swap With Basic Tools
Installation requires opening the bottom case, disconnecting the old pack and connecting the new one using the existing cable and screw points. The battery ships with short-circuit, overheat and overload protections already active. The most common issue is ordering the wrong voltage or part number, so verify the 11.4 V rating and B31N1345 code on your original battery before fitting.
Confirm Model Code and Voltage Before Ordering
Check the sticker on your current battery for the exact part number B31N1345 or B31NI345 and the 11.4 V marking. Cross-reference your laptop model against the supported TP500LA, TP500L, TP500LN and TP500LB sub-model lists supplied by the manufacturer. Units outside those lists or showing a different voltage will not be compatible.
