If you don’t follow basic safety rules for your M7 Spider area denial system’s lithium batteries, equipment damage or even injuries could result!
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:
- Replace all four batteries at the same time, using only fresh or fully charged batteries.
- Always replace with batteries from the same contract number found on the battery label. Mixing batteries with different contract numbers, manufacturers or dates can create safety and operational issues.
- Remember that not all batteries are created equal, even if they look the same. Never mix batteries and never use a non-rechargeable and a rechargeable version of the batteries at the same time.
If you have an incident with a rechargeable battery, report it to CECOM Directorate for Safety at APG:
