Hi folks, My Quick Charge Select-A-Charge charger is getting old as are my lead acid batteries in my S-10 http://www.evalbum.com/3739. I've been using them for about 2 years and have about 450 cycles on them.
For the past several weeds the charger never seems to get up to the target voltage. The display seems to get stuck at about 55-60% (varies a little from one day to the next) and then it just times out after about 11 hours. Using my DVM it looks like it's hitting about 135V or so which is quite low for my 120V pack. Clearly I'm undercharging my batteries. I sort of knew this would happen as I bought the charger used and it's only rated for batteries up to 150 AH and mine are 170 AH Trojan T-875s. It also only puts out 10 amps at 110V so I may have been undercharging since day 1. Anyway I ordered and have now received an Elcon 2.5KW HF/PFC charger. It's supposed to run on both 110V and 220V. I ran it last night on 110V and it seemed to work (though the voltage never seemed to get above 140V on my 120V pack - should go to about 165V according to the Trojan algorithm it's set for). I suspect that the 10 amps it puts out at this voltage just isn't strong enough for these older batteries. So I'm hoping that running it at 220V (which should put out about 18A) will do a better job. My question is this. The charger comes with what looks like a standard 110V male plug for AC input. How do I hook this up to 220V? There is nothing about this in the very minimal manual that came with the charger. Do I actually need to change the plug on end of the AC cord? Or is there some kind of adapter I can buy so I can use both 110V and 220V as available (that was why I bought this one). I'd like to be able to use public charging stations occasion for example. - Peter Flipsen Jr -------------- next part -------------- An HTML attachment was scrubbed...
