anser2 Posted February 20, 2012 Report Share Posted February 20, 2012 Having problems with batteries only lasting 1\2 hour on my magnet instead of the usual 4-5 hours. ( I use alarm type batteries). I have replaced the wiring on the magnet and bought a brand new battery , but still only getting 1\2 an hour from them. Anyone else had such problems , if so did you manage to cure it ?

Cosd Posted February 20, 2012 Report Share Posted February 20, 2012 How many amps are the batteries you're using? Quote Link to comment Share on other sites More sharing options...
anser2 Posted February 20, 2012 Author Report Share Posted February 20, 2012 (edited) Sorry as Webber has just reminded me I should have stated the type of battery. Yuasa REC 12-12 12v 12 Ah lead acid type. Also Haze HSC 12-7 12 v 7 ha C10 to 1.7 vpc which is brand new.

mpk Posted February 20, 2012 Report Share Posted February 20, 2012 If I remember correct a rotary uses 2ah which means a 17 ah battery will last for 8-9 hours. I have also heard of knackered speed controllers drawing excessive current ......maybe this is were the issues lies ? I use a car battery (although it is a totally new thing for me) Quote Link to comment Share on other sites More sharing options...
deny essex Posted February 21, 2012 Report Share Posted February 21, 2012 Something should be running pretty hot to use that much current, check if anything seems over hot. Have the batteries checked , if you fast charge them you can damage them , they need slow trickle chargeing. Try a known good battery and see if you get the same result to eliminate a battery fault.opps just read you have done that Bypass the speed controler and see how long the battery lasts , if its still the same short run time then the motor is suspect as K acked. make sure the lead from battery to rotary is not too thin, that can burn up power like a heating element especialy if very long, Battery lead needs to be roughly capable of carrying 5 amp max, (about vacum cleaner thickness is adquate.) it is possible with the three spade connection wiper motors to get the conections wrong if stripped down, wireing up the slow speed + and the fast speed + instead of the normal - and + can make the motor turn but burn up power,( the + and - connections are not always shown on the motors, referal to the wireing diagram from the vehicle it fits or by checking by someone with car electrical knowledge or rotary manufacturers) A matter of elimination one by one is the only way to find out.

coptleigh Posted February 22, 2012 Report Share Posted February 22, 2012 Just to jump on this thread!! how long is the ideal/maximum, from the battery in the hide, with a speed controller on to the rotary in the pattern!!!

Cheers Alan If you use a 17 AH battery as many do (or the equvalent in smaller batteries) , around 8 hours run time as an average , a long lead will make it slightly less but not much. A few variables in calculating , some motors take less current and have a longer run time , some more current and shorter run time. Quote Link to comment Share on other sites More sharing options...
activeviii Posted February 24, 2012 Report Share Posted February 24, 2012 i get a days shooting out of a 7Ah battery in the winter and then a 12Ah will give me a full summers day with no problem, but then i dont use a windscreen type motor in the rotary.

andy_s Posted February 24, 2012 Report Share Posted February 24, 2012 My home made magnet draws 6amps so even a car battery only just lasts all day. I suspect my motor isn't the best though. It was one I bought of "The Bay" from a scrap Ford Mondeo. Quote Link to comment Share on other sites More sharing options...
coptleigh Posted February 24, 2012 Report Share Posted February 24, 2012 Thanks for that Deny, but my question was, is there and ideal or maximum length of cable to be used ( from battery to magnet), ie 10/20/30 metres and what sort of amp capacity should it be??

Cheers Alan Personally I would keep it a little longer than the magnet arms so you don't get bonked on the head with a dead pigeon when you plug it in. Why would you want loads of wire sprawled across a field, would only be a matter of time before you trip up on it... That's my view anyway Quote Link to comment Share on other sites More sharing options...
coptleigh Posted February 24, 2012 Report Share Posted February 24, 2012 Well my thoughts were, that with the battery and speed controller in the hide, you could adjust speed/switch it on and off without leaving cover!! Quote Link to comment Share on other sites More sharing options...
deny essex Posted February 24, 2012 Report Share Posted February 24, 2012 Well my thoughts were, that with the battery and speed controller in the hide, you could adjust speed/switch it on and off without leaving cover!! True makes it easy to adjust but a lot more fuss to move the magnet around to suit the day and like I said roughly the wire thickness thats used on a vac min as a rough guide , 2 core if you can get it and want to run it at a long length, there is no real ideal length just what you rig your rotary to work on and does what you want it to. Personaly I'm with Cosd on the length of wire , especialy if you use a dog or likely to which I sometimes do, great for them to trip over/tangle with and cause havoc with the electrics and maybe themselves.

top shot Posted February 24, 2012 Report Share Posted February 24, 2012 i had exactly the same problem with my magnet i ended up gettin a car battery for cars not too heavy either works a treat and last a whole day Quote Link to comment Share on other sites More sharing options...

Anyone else had such problems , if so did you manage to cure it ? this may sound stupid but have checked that your battery charger is acutally charging! i had this a few years back thought it was the battery but it turned out the charger was faulty the charge light was on but it was not charging Edited February 24, 2012 by cocker3 Quote Link to comment Share on other sites More sharing options...
stu nesling Posted March 4, 2012 Report Share Posted March 4, 2012 i used to use a long wire to the rotor to enable me to turn it on or off as the crows really flare from the magnet round here. gave up on the idea a while ago as the extra weight of a big spool of wire and the voltage drop over the cable length made it a real pain......especially when you had to carry it a long distance. just extra weight i didnt want. if you look around you can get a remote control with on/off and fast/slow speed adjustment that should sort you out.

ayano3 Posted March 4, 2012 Report Share Posted March 4, 2012 I dont even have a speed control and on off switch etc. I just have about a 3m cable that goes straight from the battery to the motor. I have several different ApH batteries but have found the 7ApH ones last more than a days shooting. Try shortening the cable, clip it straight to the battery and see if that cures the problem. None of the pigeons I have shot have commented on the speed of the magnet. Quote Link to comment Share on other sites More sharing options...
