i just got a new battery for minei should charge and drain it a few time at home before running it in the field?9v walmart battery > VR box > JB3/UA5
Quote from: Bean on October 09, 2005, 05:29:01 PMwhats the ua5's run on voltage wise I believe its reccommended for 9V or more, but Im pretty sure people have run it on 7.2 without issues. It is definately the battery, I ran it again today until the ua-5 wouldn't power on at all, to try to drain it as much as possible, then I hooked it up to the charger and immediatley the green light on my charger came on saying it was done charging, really odd because the battery awas sitting around for MAYBE 10 days since it had been charged last, never had any issues with it before, im gonna see if I can exchange it with the company I bought it from on ebay, luckily I just bought 2 more from Kresby on here so I have backups on the way. i tried the other battery, freshly charged just to make sure it wasn't an issue with the VR-box and it worked fine for 15-20 min which is much longer than the other one would run it so hoping it was just the battery at this point. thanks for all the feedback guys, if i learn anything more I'll be sure to post +Ts for all

A phrase above that scares me--"drain it as much as possible". You CAN deep discharge NiMH, and that will kill the cells.
No, cycling is still a very good thing, just don't drain it too far at the end of the cycle. When it gets down to about 1V per cell is when you want to stop (8V on the pack your using).
