Alistair Posted March 31, 2013 Report Share Posted March 31, 2013 Hi All, I am looking for a good battery for a magnet that will last at least 8 hours. I was out yesterday in Perthshire and the small battery I had only lasted 3 hours. Another question about recharging, I have been told to recharge on a slow speed, is this right and why? Cheers...

TIGHTCHOKE Posted March 31, 2013 Report Share Posted March 31, 2013 Slow charging that will then turn to trickle charging is the way to go. You need a fully automatic 12v sealed lead acid battery charger. As for batteries I have a ready supply of 12V 7 amp hour batteries so take a couple along and change over when they get tired. A larger capacity battery should give you longer, a 22 amp hour should last you all day. Good luck T.C. Quote Link to comment Share on other sites More sharing options...
Mike737 Posted March 31, 2013 Report Share Posted March 31, 2013 I bought this off the 'bay' http://www.ebay.co.uk/itm/271136103333?ssPageName=STRK:MEWNX:IT&_trksid=p3984.m1439.l2649 Seems very good, runs mine for hours, though I only use foam decoys on it, not real pigeons. It's 20 AH rated, Lucas branded, and cost £26.48. I think that slow charging is better because it generates less internal heat, and reduces the chances of warping the plates. Carrying one battery seemed better than 3 smaller ones, though I will make a little carrying cradle for it, as it's quite heavy, and I wouldn't want it to slip through cold wet fingers and smash... Hope that helps, Mike. Quote Link to comment Share on other sites More sharing options...

TIGHTCHOKE Posted March 31, 2013 Report Share Posted March 31, 2013 Ampere Hours, the amount of work the battery can be expected to do. Quote Link to comment Share on other sites More sharing options...
