This Cameron & Co DS-CS-AUP500NB battery replaces part numbers 0B200-00990100 and B31N1345 in Asus Transformer Book Flip TP500LA, TP500LB, TP500LN and TP500L models. It is a direct-fit lithium-polymer pack for owners of those specific devices who need a new power source.

Li-Polymer chemistry and 47.88 Wh capacity

The battery uses lithium-polymer cells rated at 11.4 V and 4.2 Ah, delivering 47.88 Wh of energy. Li-Polymer construction typically runs cooler and lighter than older chemistries, so normal use stays quiet and does not add noticeable heat to the chassis.

Black finish and exact chassis dimensions

The pack measures 204.14 x 157.74 x 7.00 mm in a black housing that matches the original aesthetic. No cables, tools or software are bundled; the accessory change is limited to restoring mobile runtime for the listed Transformer Book Flip models.

Questions about this item

How do I install the DS-CS-AUP500NB battery in my Asus Transformer Book Flip TP500LA, and which step is often missed?

Power off the laptop, remove the bottom case screws, disconnect the old battery connector, fit the new 204.14 x 157.74 x 7.00 mm pack, reconnect the cable securely, then reassemble; the step most often missed is fully seating the connector before closing the case.

What maintenance or replacement will the Li-Polymer 4.2 Ah battery need over time?

Li-Polymer cells require no scheduled maintenance; expect gradual capacity loss after several hundred charge cycles, so plan to replace the pack when run-time drops below your needs.

What limit appears first during sustained use of the 11.4V 47.88 Wh battery?

The 4.2 Ah capacity sets the runtime ceiling; under continuous load the pack will deplete before any thermal or voltage limit is reached.
