Xeno 3.6v Batteries

[morrisjs]

Hey,

Just stumbled on this forum and had a question. Ive basically got an endless supply of XenoEnergy XL-200F D Size 3.6 Volt 16.5Ah Lithium batteries and i was wondering if these are safe to use in a standard 2d or 3d Maglight?

Thanks for the help! - Jarod

Safe? Maybe. Worthwhile? Not really. Those cells are rated for 230mA continuous current only. See the data sheet for them here: http://www.xenousa.com/pdf/XL-200F.pdf

At a discharge rate of 200mA, the cells are rated for only 3.7Ah, which is really poor.

Actually, these batteries may not be so safe, either! These are of the type Thionyl Chloride Lithium, which according to Wikipedia:

Thionyl chloride Lithium tetrachloroaluminate in thionyl chloride 3.5 V

Liquid cathode. For low temperature applications. Can operate down to −55 °C, where it retains over 50% of its rated capacity. Negligible amount of gas generated in nominal use, limited amount under abuse. Has relatively high internal impedance and limited short-circuit current. High energy density, about 500 Wh/kg. Toxic. Electrolyte reacts with water. Low-current cells used for portable electronics and memory backup. High-current cells used in military applications. In long storage forms passivation layer on anode, which may lead to temporary voltage delay when put into service. High cost and safety concerns limit use in civilian applications. Can explode when shorted. Underwriters Laboratories require trained technician for replacement of these batteries. Hazardous waste, Class 9 Hazmat shipment. ​
