We received a CB3-111-C670 in for battery replacement, only to find that the battery had already been removed and was missing.
The 3-cell battery part number KT.0030G.004 / AC14B18J(3ICP5/57/80) (11.4V/3220mAh/36Wh/3S1P) was the first to come up. But we’re also seeing that 4-cell battery part number KT.0040G.004 / AC14B18K(4ICP5/57/80) (15.2V/3220mAh /48Wh/4S1P) being listed for the CB3-111. Both batteries use the same plug, same number of wires, and have identical wire colour codes. They’re identical with the KT.0030G.004 having an empty section missing a Lithium Polymer cell.
So the question is:
Are the KT.0030G.004 and KT.0040G.004 interchangeable on the CB3-111-C670, with the KT.0040G.004 giving extended battery life?
Or is there only one of the batteries meant for this model, with some indicator on the motherboard to choose the correct battery?
It seems extremely odd that Acer has manufactured two physically identical batteries without some form of interchangeability.
