Me matt Posted July 23, 2017 Report Share Posted July 23, 2017 As above, I have an A1 decoys 7ah battery that I've charged about 10 times since purchase. Put it on charge today for a few hours as was practically dead from last outing and have a shoot planned for Friday. On passing the battery after a couple of hours charging I noticed a smell and spotted it has ballooned in the centre on both side walls and was also red hot. Anyone experienced this before? Is it likely to be a faulty battery as its only 3 months old... charger has been ok- I use it for some ride on mowers I have on contracts and they have charged ok. Thanks in advance MM Quote Link to comment Share on other sites More sharing options...
TIGHTCHOKE Posted July 23, 2017 Report Share Posted July 23, 2017 Could you have got the polarity wrong? Quote Link to comment Share on other sites More sharing options...
Me matt Posted July 23, 2017 Author Report Share Posted July 23, 2017 Could you have got the polarity wrong? No, red always goes to black 😂 Seriously though - polarity was correct and the charger on initial connection indicated a slightly less than flat battery on the gauage.

Mr gen Posted July 23, 2017 Report Share Posted July 23, 2017 could be a dry battery my son bought a new battery for his motor bike, it did the same thing, within a month. took the top off it and it was bone dry. Quote Link to comment Share on other sites More sharing options...

fortune Posted July 23, 2017 Report Share Posted July 23, 2017 Plates are buckeld, !,,its scrap. Shorting out inside.. not necessarily. I hooked up a similar battery that I used for lamping to the battery charger and it had been set on 24 volts for the fork lift. I didn't look. It had been on charge a while and I noticed jets of steam coming out of the battery. it was so hot that I couldn't touch it. the sides were all bulged like a six pack. I thought Oh ********, thats tonights lamping gone west. anyway I tried it on the lamp and it was ok. in fact it was the best lamping battery I ever had. it was brilliant and seemed to have endless power. It lasted about three years of hard work before it packed up. You might be lucky. Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted July 24, 2017 Report Share Posted July 24, 2017 Not sure what charger you are using, but these type of batteries are better suited to a trickle charger. Quote Link to comment Share on other sites More sharing options...
Me matt Posted July 24, 2017 Author Report Share Posted July 24, 2017 Thanks for all the replies. I will try it out after work & report back. My charger isnt a trickle type, if battery is fubar I will also pick up a trickle charger for it. Strange thing is- my sit on mowers have the same batteries and they have been fine for over a year on this charger. Will also check battery level later.

They work well, don't get hot and use very little electricity. Ebay # 361434462838 Quote Link to comment Share on other sites More sharing options...

Thanks in advance MM Hi Me matt, Our batteries do have to be charged on a trickle charger, we sale the chargers for around £12 inc postage. I'm guessing that may be the problem. We don't get many faulty at all (I mean about 2 in 6 months really are faulty) Please let me know how you get on. Aimee @ A1 Quote Link to comment Share on other sites More sharing options...
Me matt Posted July 24, 2017 Author Report Share Posted July 24, 2017 Well- its still powering the rotary, seems to have the same speed/power so ill give it a day out on Friday and see how it holds up. @ Ammie - maybe a good idea to include the fact it should only be trickle charged at the point of sale?? Not that its any different to any other battery I charge on this charger for my machinery. Quote Link to comment Share on other sites More sharing options...
ChAoS Posted July 25, 2017 Report Share Posted July 25, 2017 Our batteries do have to be charged on a trickle charger So why does it state on the battery "constant voltage charge" and "initial current 2.1A"? This sounds like a bog-standard lead acid gel battery which should self-limit if placed on a constant voltage supply. I see no reason why this battery should be trickle charged. Am I missing something, here? Regards, Mark. Quote Link to comment Share on other sites More sharing options...

Some listings should have on them that the batteries should be trickle charged. Please PM us 'Me matt' and we'll happily send a replacement as you were not aware they should be trickle charged, that is our fault for not making it clear - apologies.

fortune Posted July 25, 2017 Report Share Posted July 25, 2017 I think that the general rule is 1-10th of the capacity. Thus about 700 milli amps. How the battery that I loaded up up with 24 volts at about 60 amps managed to survive is a bit of a mystery. It was the best battery that I ever had.

I think that the general rule is 1-10th of the capacity. Thus about 700 milli amps.The problem isn't the battery, it's the charger. These batteries don't need trickle charging - they need a decent charger or bench power supply. It's a long time since I bought a car battery charger but, in the days when I *did*, what they supplied in the way of power tended to be *very* "dirty" indeed. This wasn't a problem for large lead-acid batteries but for small ones... :( I use quite a few different sizes of SLA batteries and all get charged in one of two ways: [a] If the "go fasterer" charger isn't in use, I use *that*. It has a special setting for SLAs and you just have to sepecify the terminal voltage. (That is, the number of cells in the battery.) Else, I set the PSU to 2.3V per cell (13.8V for a 12V lead-acid battery) and let rip. As I said above, the *initial* charge will be high but the battery will self-limit and end up float charging. I *really* like SLA batteries: cheap, reliable (low self-discharge) and easy to charge. However, compared to the more modern batteries (eg, lithium) they have realtively low capacity and are, of course, heavy. Regards, Mark. P.S. Kudos to A1 for decent customer service. Well done.
