== What ==
There were 4 packs and some singles of lithium batteries laying around the Base. I took them, cracked open the cases, tried to recharge individual cells. Kept the cells that are able to hold some charge, dumped the others into according type of waste.

== Why ==
* I wanted to assemble a battery pack for our devices.
* Lithium batteries degrade when shelved and uncharged.

== How ==
* Cut the side opposite to terminals with a hacksaw, then pry carefully until it cracks open.
* Measure the pack for undervoltages.
* If no undervoltages, try to charge the whole pack. Note the number.
* Disconnect from the control circuit and cut some metal strips to be able to charge individuals.
* Cycle-charge indivudial cells and mark the capacity measured.
* Keep the good ones and profit.

== Equipment used ==
* IMAX B6 charger
* 3 x 8 cell pack, 1 x 3 cell pack, two cell phone batteries

== Result ==
* Cell phone batteries had cap. 400 mAh, were dumped.
* Out of 27 individual LiIon cells 14 were dead.
* The capacities of the rest lay in the interval of 700 - 1600 mAh (these have original capacity 3000 mAh and more)
* The good ones are being cycle-charged to confirm the capacity for possible re-packing.
