Boeingman Posted July 19 For those more technically minded than myself. I have a magnet battery which is a 12v 7Ah battery which is on its last legs. If I buy a new one which I want to last longer than the original, do I just up the Ah side of things. What do people use? Quote Share this post Link to post Share on other sites
JTaylor91 Posted July 19 I use a 12v 17ah. I pack up before the battery does. Quote Share this post Link to post Share on other sites
miki Posted July 19 7Ah = 7 Amps for 1 hour (or 1 Amp for 7 hours) Typically (I understand) the pigeon magnet will draw 2Amps so a 6Ah battery would last 3 hours from fully charged to fully flat (in a nice linear world) - however voltage will drop as the battery loses charge so a 7Ah battery will probably last 2.5 to 3 hours, a 12Ah battery 4.5 to 5.5 hours and a 17Ah battery 7 to 8 hours (max). Based on the above and your original question @Boeingman yes, up the Ah. I'd (personally) avoid a 'lead acid' battery (unless it's "sealed") and go for a Gel or AGM battery. Batteries can lose their ability to hold charge and 'lead acid type batteries' are best left on a low/trickle charge to avoid sulphation (which is what forks them).

Boeingman Posted July 20 Cheers miki, I know there is always someone smarter than me. I’ll go searching eBay😁😁 Quote Share this post Link to post Share on other sites
Wooder Posted July 20 tool station sell them, if there is one near you! Quote Share this post Link to post Share on other sites
Boeingman Posted July 21 anyone got one of these. Any good. Only £32 delivered😳 Quote Share this post Link to post Share on other sites
Balotelli Posted July 22 Lithium ion is undoubtedly the way to go. Half the weight, more power and deep cycling but at £80ish a pop a bit pricey. I guess give it time and the price will come down. Meanwhile I'll carry on yomping my lead acid batteries and hernia. Quote Share this post Link to post Share on other sites
