0 Ed Carlson Posted July 23, 2009 Share Posted July 23, 2009 If they are really dead...and they were good but maybe just not charged on schedule...put them on a good smart charger for up to 6 days. I have seen many recover, it just takes a long time. If they do not hold there charge then...they be dead done deal.If she be shot...don't dink around with a 7 amp battery to save a buck...not worth it...go to the 9 amp for a replacement. The 8 amp is better than the 7 but in this case more is most certainly better. High watt flashers and underwater cameras need more amps, more reserve capacity, and quicker recovery charging, and a good 9 amp fills that bill best.

0 Jeremy airjer W Posted July 23, 2009 Share Posted July 23, 2009 The best way to check them is to see how long they last. When you start noticing the run times diminish its time to replace. Oddly enough I have had the best luck with the WERKER brand from batteries plus. Go Figure? Quote Link to comment Share on other sites More sharing options...
0 DTro Posted July 23, 2009 Author Share Posted July 23, 2009 Thanks guys, I was kind of looking for a way to quickly test the batteries I have. Some sort of load test. Quote Link to comment Share on other sites More sharing options...
0 Ed Carlson Posted July 24, 2009 Share Posted July 24, 2009 Since they are not a staring battery, Amp load testing may not do much good...they are designed for longevity of use. The best test is charge it up fully, see how long it takes to drop to a unusable level for the device your using it on. Quote Link to comment Share on other sites More sharing options...
