i found 4 in an old battery pack for a very old version of the Asus "EEEPc" minilaptop.

the pack had 4 cells, it says 5200 mAh which calculates /4 to 1300 mAh per cell. Thanks to @Geopelia and @ZipZwan for the correction, it is by the labelling on the pack going to be about 2600mah per cell (dont forget to include voltage calculation when calculating amp hours)

it was very hard to get apart but it did look like 2p2s from the arrangement of tabs. epsecially since it shows 7.4 volts (which would give 3.7v per cell)

No bro its not 1300

Bro because this pack is 2s2p so you should divide the entire capacity of 2.

5200/2 : 2600 mah

so design capacity per cell is 2600 not 1300.

Correct on laptop Batt's, they write on outside capacity of 2S pack, not capacity of total batteries!! Logic cap of 1 cell is /2

WOooooooops!!! Thanks for the correction.

For anyone following, another way to calculate is like this.

Case says 5200mah, at 7.4 volts. That is 38.48 watt hours

divide by 4 cells, thats 9.6 watt hours per cell

divide 9.6 wh by 3.7v, the voltage of each cell, and thats 2.6 ah.

aka 2600 mah.

The reason i cannot just divide 5600mah by 4 is because that is disregarding the issue of how the batteries are arranged giving 5600mah at 7.4 volts which would be different if the batteries were, say, all in parallel at 3.7 volts or all in series at 14.8 volts.

Thanks again @Geopelia @ZipZwan
