harpoonlouis Posted March 29, 2009 Report Share Posted March 29, 2009 Got a battery with my magnet that is marked 7 Amp/h and is simialr to those in golf trolley, small scooter etc. First run with flattened it in 40 minutes. Currently on charge to test again. Anyone have an idea of how long a good condition battery should last? Quote Link to comment Share on other sites More sharing options...
Shooting Tom Posted March 29, 2009 Report Share Posted March 29, 2009 Hey mate, i had the same problem as well, now i use a car battery whhich will last all day. You could from using a speed controller on your magnet... ? But i use a car battery now. but they cost about £50. . . . But better than charging it ever 40 mins i didnt even think my battery lastest that long at fall speed lol. Quote Link to comment Share on other sites More sharing options...
Warlock Posted March 29, 2009 Report Share Posted March 29, 2009 12v 17amp/hr lasts me 8 - 9 hours. Quote Link to comment Share on other sites More sharing options...
dusk2dawn Posted March 29, 2009 Report Share Posted March 29, 2009 12v 17amp/hr lasts me 8 - 9 hours. I have tested my 17amp with the rotary going continuously on the lawn allday, just to see!! It was still turning 12hrs later when I stopped it as it was getting dark, the secret with these batteries is to fully recharge them after each use, allways storing them recharged and to fully discharge them 2/3 times a year. This battery is now 3yrs old and I use it lamping fairly often as well. IMO a magnet requires a beefier battery than a 7amp/hr.

Cranfield Posted March 29, 2009 Report Share Posted March 29, 2009 I use Yuasa 12V 7AMP batteries for my rotary and they have always given me a good days use. Quote Link to comment Share on other sites More sharing options...
Imperfection Posted March 29, 2009 Report Share Posted March 29, 2009 I use Yuasa 12V 7AMP batteries for my rotary and they have always given me a good days use. Thats what i have too and provided i dont have the speed controller set at warp 9-its lasts me about 4.5hrs.Maybe more if i set it a tad slower,but only used it a few times and experimenting with speed.

activeviii Posted March 29, 2009 Report Share Posted March 29, 2009 depends on the magnet. A friends magnet that came with his hyper flappers is a 3.4amp and last all day and more. the one that come with my pinewood is a 7amp and the one i have on another magnet is a 17amp, this one last a few trips. what magnet is it, whats in spinning and are you using a speed controller.

dusk2dawn Posted March 29, 2009 Report Share Posted March 29, 2009 I use Yuasa 12V 7AMP batteries for my rotary and they have always given me a good days use. AHHH you use batter(ies) whereas I use a battery, how many 7amp jobbies do you get through during a full day? I can tell you during a nights lamping, but not using a magnet, so I will have to bow to your superior knowledge.

Cranfield Posted March 29, 2009 Report Share Posted March 29, 2009 I also believe it depends what rotary you have and mine is a Pinewood Advantage (10 years vintage). D2D, I only use one battery at a time, but as I am shooting almost 5 days a week, I have a number in circulation and they are all Yuasa brand (IMO the best battery you can buy). I am glad the sun shone on you today at the Fair. Quote Link to comment Share on other sites More sharing options...
shadow mag Posted March 29, 2009 Report Share Posted March 29, 2009 12v 17amp/hr lasts me 8 - 9 hours. 7amp wont last long. when i bought my magnet they said i needed a 17amp to last the day Quote Link to comment Share on other sites More sharing options...
webber Posted March 29, 2009 Report Share Posted March 29, 2009 I sell Yuasa batteries. Please PM with enquiries. webber Quote Link to comment Share on other sites More sharing options...
harpoonlouis Posted March 29, 2009 Author Report Share Posted March 29, 2009 Thanks for the comments. This is not a branded battery like Yuasa so may be a quality issue. Not sure if it is a speed controller but the only component visible apart from the motor gearbox is a little heatsink like thing with a turnable shaft in the centre, rheostat? Will test again tommorow. I have a ton of car batteries for clay traps, small Ford KA size that work a treat and only weigh about half the norm for a family car so could use one of those. Glad I tested before setting off in to the middle of the countryside! Quote Link to comment Share on other sites More sharing options...

foggy11 Posted April 25, 2009 Report Share Posted April 25, 2009 Just a quick note to say..... A 7 amp hour battery lasts 6 full hours with a normal magnet on a moderate speed before it starts to slow down... B) Quote Link to comment Share on other sites More sharing options...

kennym Posted May 5, 2009 Report Share Posted May 5, 2009 SAVE YOUR MONEY, Car battery's are anything from 30 amp hour to 120 amp hour, me & willc have been using a knacked one with a duff cell battery giving only 9 Volts & it did a 12 hour shift on the pigeons this week So a bad car battery will last longer than a good dry cell battery, ( no offense to the lad who sells em ) OK their bigger & heaver, but you can get one from a scrap yard for a fiver, Make sure its a black one, get yer paint brusher out & camo it Ken. PS if you live near me don't be beating me to the scrappy on Saturday Quote Link to comment Share on other sites More sharing options...
chrispti Posted May 5, 2009 Report Share Posted May 5, 2009 Try a new halfords car battery, will last 4 days 3 year warranty too! when you get to the 3 year point, just leave it flat and take it back for a free exchange Quote Link to comment Share on other sites More sharing options...

willc Posted May 6, 2009 Report Share Posted May 6, 2009 Same for me who wants to lug a bloody car battery round a field with them I get my enthusiastic shooting partner to carry it, that or stick it in the jeep. We are lucky tho, as kennym says, new permission leaves a 6 foot plus strip round all the fields for conservation, so access is good.
