18650 batteries

18650 battery cells harvested from laptop batteries. None is swelled, corroded or leaking, these were discarded. Cells are not tested.
Naturally, some of them will be weak but there should be plenty of healthy good ones in the mix. This is reflected in the price.

Price is 20 euro for 100 cells (1x100)

Sold in 100 cells lots only. 800+ cells available.
Various brands, a mix of every manufacturer out there like Sony, Sanyo, Samsung, LG...

Every negative cell terminal is taped over with electrical insulation tape. The price is for collection. Shipping only through courier (preferably DPD) at buyer cost - price will depend on size and weight.
100 cells fits in a box I use for shipping.

There is no cheaper option due to weight, and only some couriers accept to ship lithium batteries. Collection is always free.
