You can purchase a "smart" battery charger that uses a microprocessor to monitor charging and will not overcharge or damage your battery. I don't know what the model 177 uses offhand is, but some googling would turn up potential models. Feel free to visit us in our pit in Atlanta to ask.

Careful with this circuit. Lots of people who know more about electrons than me were questioning its performance at the beginning of the year, and I don't know if FIRST or IFI has made any modifications to improve it. Generally, my experience is that if you switch out your backup battery once or twice a day you'll be fine.
