Re: battery problems and fix?

Some of our standard practices:

- ALWAYS lift by the case, NEVER by the battery leads
- ALWAYS check for shorts before plugging something in. This only takes a few seconds with a multimeter
- Fully charged batteries get one of the white Anderson tabs stuck in them to indicate they are charged.
- Drivers are trained to swap batteries often.
- For batteries used for "bench top tests" (in other words, to run motors directly as we debug mechanical issues), we replace them at minimum every 2 hours, more often ever hour. As these batteries don't discharge much, they recharge very quickly.
- at every meeting, the first thing we do is to plug in all uncharged batteries.
- At every meeting, the last thing we do is unplug all charging batteries.

Something important to note: If the batteries are left plugged into the chargers and the chargers are unplugged from the wall, the batteries WILL drain back into the charger, leaving you with a dead battery the next morning.
