The BB-2590/U rechargeable lithium-ion battery is great because it’s lightweight and its charge lasts a long time. But if you don’t charge it the right way, you could be in for trouble.

Using chargers with out-of-date software can cause a fire. One recent fire caused $5.5 million in damage! Follow these tips to avoid expensive damage to equipment and personnel injuries:

  • Battery maintenance. First, fully charge lithium-ion rechargeable batteries before using them the first time and at least once a year afterwards. Don’t use commercial versions of Army-issued batteries or chargers. They aren’t approved for military use.

Batteries approved for military use will have a contract number above the date code. Military-approved chargers have the contract number listed on the charger faceplate.

  • Inspection. Check the program label on your charger to find if its software needs to be updated. The correct software version is Program H for PP-8498/U soldier portable chargers (SPC), NSN 6130-01-495-2839, and Program C for PP-8481B/U vehicle mounted chargers (VMC), NSN 6130-01-527-2726. Note that the PP-8481A/U charger on the move (COTM), NSN 6130-01-494-9164, cannot be updated.
  • Software update. If you need updated software, go to this website to download and install the correct version:

   You’ll need a USB-to-serial cable such as NSN 6150-01-558-7214, or a DB9 male to DB9 female serial cable with straight through connections. Do not use a null cable.

  • Monitored charging. If you have to charge batteries before you can update your charger’s software, don’t leave the charger unattended. That’s a fire hazard. Signs of trouble include batteries that are hot to the touch or have smoke coming from them. It’s a good idea to always keep a fire extinguisher on hand while the charger is in use.

Also, don’t charge more than two batteries at the same time if the software is out of date.

Check out the user manual or the matrix printed inside the charger lid. Both’ll tell you how to properly interpret the charger lights so you can avoid overcharging the batteries.
