Second question, I tried it with a new battery and a very lightly built magnet and hyper-flaps. It lasted about 4 hours so with the extra weight of dead birds, i would guess about 2-3 hours. Giving it a go is the best way to find out. Quote Link to comment Share on other sites More sharing options...
mad1 Posted January 3, 2012 Report Share Posted January 3, 2012 Charge it slowly also not a fast charge as I might be wrong but it don't think it does them any good Quote Link to comment Share on other sites More sharing options...
deny essex Posted January 3, 2012 Report Share Posted January 3, 2012 If you take as an average power consumption of 2 amps per hour for a 2 dead bird loaded magnet a 7.5amp battery will last approximately :- 7.5 divided by 2 = 3.75 hours. A magnet with hypaflaps will last a bit longer being a lighter load , wind and temperature can also alter the running time slightly. Quote Link to comment Share on other sites More sharing options...

Even as an average Be a good calculation to know? Quote Link to comment Share on other sites More sharing options...

In my mispent old age I spend a lot of time fiddleing with kit, magnets I have made and tested as per various wiper motors used measure between 1.5 amp and 2.5 amp under indoor conditions loaded, it does vary wiper motor to wiper motor but if you use 2 amp per hour as an average for battery consumption you wont be far out. Most people find a 17amp hour battery more than adequate for a days full runing. Edited January 3, 2012 by deny essex Quote Link to comment Share on other sites More sharing options...

AlistairB Posted January 3, 2012 Report Share Posted January 3, 2012 oh....and keep your batteries indoors, they'll hold a charge better over time. AB Quote Link to comment Share on other sites More sharing options...
steve_b_wales Posted January 3, 2012 Report Share Posted January 3, 2012 When not in use, I keep all my batteries topped up by using trickle chargers on them. The chargers use very little electricity, and cost around a fiver off Ebay. Quote Link to comment Share on other sites More sharing options...
woodcock1 Posted January 3, 2012 Report Share Posted January 3, 2012 I only use my magnet round harvest time for a few weeks. When im finished I drain the acid from the battery rinse it out with water and store upside down with the water caps off. My local motor factors fills it for me for free or £1 each season. Ive had the same battery 9 years now. Not sure if it its worth it but ive got into the habbit. Quote Link to comment Share on other sites More sharing options...
