Replacement Battery for Acer TravelMate P4

This 11.61 V lithium-ion cell delivers 4821 mAh and 55.97 Wh of capacity. It replaces part numbers AP19B8M and KT0030G024 in compatible Acer TravelMate P4 TMP414-51 and Swift 3 SF314-59 series notebooks. The black pack is supplied new with a 12-month warranty.

Upgrading from a Depleted Original Cell

When the factory battery no longer holds a useful charge, this unit restores the original runtime without modifying the laptop. The swap is worth it when the machine still meets performance needs but battery life has dropped below a workable threshold. No firmware update or hardware change is required.

Fits Inside the Existing Battery Bay

The pack occupies the same internal bay as the original cell, so no case modification or external adapter is needed. It frees the user from permanent mains tethering and restores portable operation for the supported TravelMate P4 and Swift 3 models. Compatibility covers the listed sub-models including SF314-59-78Z8, TMP414-51-59MR and Porsche Design Book RS AP714-51GT variants.

Questions about this item

Does the KT0030G024 battery fit the Swift 3 SF314-59 chassis without extra brackets?

Yes, it is listed as a direct replacement for the Swift 3 SF314-59 series and TravelMate P4 TMP414-51 models, matching the original AP19B8M form factor.

What is the common installation mistake with the AP19B8M battery connector?

The multi-pin connector must be fully seated before the bottom case screws are tightened; a partial seat causes a no-power condition.

When should the 4821 mAh pack be replaced?

Replace it when a full charge no longer lasts through your normal workload or the system reports a significant capacity loss.
