Green Bum Posted May 3, 2016 Share Posted May 3, 2016 Hi Guys, I am looking for a set of second hand batteries to use as back-up batteries on my 3kw infini hybrid inverter. As I understand they will not be used until a power failure. Looking at our load shedding history I will want them to provide 800W for two hours during load shedding (computers and admin stuff no real peaks) With our national electricity demand down by 10% and our office not working during peak hours I don't expect the batteries to be used more than say 20times in the next 3-4 years, so I will be happy if I can get a life of 3-4 jr's from the batteries. Any ideas or offers and do you think my reasoning makes sense Thanks Godfried Quote Link to comment Share on other sites More sharing options...
Guest Posted May 3, 2016 Share Posted May 3, 2016 Green bum, You COULD look at leisure batteries, that can have water added, to do what you need. SA Trojan Batteries have such that he can organise, I believe. Quote Link to comment Share on other sites More sharing options...
Green Bum Posted May 3, 2016 Author Share Posted May 3, 2016 Thanks, would these be second hand batteries sent back to them for replacements? Quote Link to comment Share on other sites More sharing options...
Green Bum Posted May 3, 2016 Author Share Posted May 3, 2016 I have been thinking of forklift batteries that don't last a shift, or golf cart not getting to the 18th hole. Sidewinder 1 Quote Link to comment Share on other sites More sharing options...
Guest Posted May 3, 2016 Share Posted May 3, 2016 Nope, they would be new I suspect. To get 2nd hand golf cart batts ... when you find some, I need some too, as does Plonkster. Trojan's are used till they are deader than dead, then traded in for a good lead price. Quote Link to comment Share on other sites More sharing options...
___ Posted May 4, 2016 Share Posted May 4, 2016 I think I've changed my mind about that. A golf cart that doesn't quite reach the 18th hole or a forklift that falls short of a full shift... usually has a battery pack that is pretty far gone. That's just my experience with the T125s I had. If you can find a forklift battery that has prematurely developed a bad cell, then you might have a chance... but people tend to repair those instead of throwing out the whole pack. What I do now is get UPS batteries. Those are often thrown out for maintenance reasons (every 18 months, because that is what the book says we must do), and have often spent their entire life on float. They have a life of maybe 600 cycles, but I try to buy them at a price that makes it worth it. So I buy a new bank like every year or two... waiting until that ship comes in that will help me buy the bank I really want... which is... uuuhm, I'm not sure yet. I keep reading about new and better things that are coming... :-) Quote Link to comment Share on other sites More sharing options...
Green Bum Posted May 5, 2016 Author Share Posted May 5, 2016 Hi plonkster, i like your thinking! Look at corporate ups options. I will still persue the golf option, my thinking.... golfer buys a secondhand cart, wants to consentrate on his swing not on getting to the 18th, thows out the old batteries and with new batteries he basically has a new cart! ___ 1 Quote Link to comment Share on other sites More sharing options...

Does the golf cart use 48v? If not you need to find a few meaning even more unbalanced batts Quote Link to comment Share on other sites More sharing options...
Green Bum Posted May 5, 2016 Author Share Posted May 5, 2016 Yip 48 V in luck there! Quote Link to comment Share on other sites More sharing options...

To be honest, I've only ever seen a 36V charger (in a shop, being repaired) and I was told it belongs to a golf cart. I've only seen 48V golf carts.
