What this battery replaces

The PISKEKAT AC14B18J is a new 11.4V lithium-ion pack rated at 36Wh across three cells. It matches the original specifications for a wide range of Acer Aspire, Chromebook and TravelMate models including the ES1-571, CB5-311 and B115-MP series.

Questions about this item

How do I install the AC14B18J battery in my Acer Chromebook 13 CB5-311, and what step is often missed?

Power off the laptop and disconnect the charger. Remove the bottom case screws, then use the included crowbar to gently pry the old battery connector loose before lifting it out. The step people miss is unplugging the battery cable before removing the securing screws.

What maintenance or replacement will the AC14B18J need later?

The lithium-ion pack is rated for up to 500 recharge cycles. After that capacity drops noticeably, so plan to replace the battery once runtime falls below your needs. No calibration routine is required beyond normal use.

What limit appears first during sustained use of this 36Wh 11.4V battery?

The 36 watt-hour capacity sets the runtime ceiling. Under continuous load the pack will deplete before any thermal or cycle limit is reached, giving roughly the same operating time as the original Acer cell.
