Mixing old and new batteries can cause batteries to vent. This has happened in the past with the LSH-20 lithium batteries, NSN 6135-01-463-7077, in an M7’s munition control unit (MCU) during testing of the M7E1 remote control unit.

Here’s what you need to know when it comes to lithium battery safety:
