Moley1508 Posted May 20, 2018 Report Share Posted May 20, 2018 hi all, I bought 2 12v12ah batteries from a recommended dealer and charged them each overnight as per the instructions and have used them on a flapper without issue but this weekend for the. first time I used them on a new magnet from shooting warehouse. the first battery lasted maybe an hour, the magnet went very fast to begin with then settled to a good speed then partially stopped. the second battery did almost the same but lasted maybe a bit longer but only 10-15 mins. Both had been charged over night prior. charger has charge coming through, I tested it on my tongue, won't do that again mind. any ideas? any good cheap recommended replacement batteries you can suggest? thanks in advance, much appreciated Quote Link to comment Share on other sites More sharing options...

marsh man Posted May 20, 2018 Report Share Posted May 20, 2018 When I used a few of the smaller batteries I found after a number of charges they started to fail to hold the charge , now I use the large ones and that problem haven't happened up till now. The large one I use now came off of a golfing buggy , second hand when I got , last all day and never have let me down , the down side to me is the weight , not to bad , but lugging it a long way you begin to notice it . Last year when I went up the scrap yard for some wheel studs they had a load of dry cell batteries that came off mobility scooters , so if you have a car breakers yard near you, why not give them a ring .

deny essex Posted May 21, 2018 Report Share Posted May 21, 2018 I use a 12 AH battery on either of my rotary's and have no problems with around a 5 hour plus usage. I would check the rotary motor when it slows to see how hot it is if its slightly warm then more than likely ok, if its pretty hot then suspect a motor fault in either the coils or binding up in the gears or bearings.

I also Have no problems getting 5-6 hours (rotary/magnet) from my 12ah batteries, I also have 7ah battery and can get 4-5 hours on a full charge, OP what type of charger are you using?

Shufti Posted May 21, 2018 Report Share Posted May 21, 2018 Same thing here New rotary and 12v 12ah battery , fully charged ( according to my charger) and ran only 2 hours approx ! I expected at least 5 hr. Charger only puts out 600ma . and is fine with the little flapper battery. Maybe not enough? maybe charger goes onto trickle too soon? May be battery a dud ! I'll check motor next time for temperature. AA sell 7ah batts with rotarys ...L did not reckon that would be sufficient so went for the 12ah.

dead eye alan Posted May 24, 2018 Report Share Posted May 24, 2018 Depends on the decoys, artificial are very light and need less energe to run so battery will last longer than when useing dead birds. As i have said many times brested out dead birds are lighter than full birds and so battery last's longer. Quote Link to comment Share on other sites More sharing options...
