Category : Primary Lithium Cells / Batteries

Primary Lithium batteries feature with high energy density and long shelf life. They are excellent for smoke alarm, LED lighting and outdoor devices.  However they  are not rechargeable and totally different with Li-Ion batteries.  If you are looking for rechargeable Lithium-Ion batteries, please follow this link: Li-Ion Battery section.  There are three types of chemistry in Lithium primary battery, which result in different voltage as the follows:

Li-Fe-S 1.5V AA 2900mAh, AAA  1100mAh
Li-MnO2 3.0V CR123A, Button cells
Lithium thionyl chloride 3.6V AA, 1/2AA, 2/3AA,  C, D, DD size


1. Since primary cells/batteries are non-rechargeable, do NOT connect them in parallel, unless there are diodes to prevent cells/batteries recharge from each other, from higher voltage to lower voltage ones.

2. Don’t connect primary cells/batteries more than 2 in series. Especially when cells/batteries are not in balanced status, this might lead forced over discharge which will generate heat and might cause explosion.
