DURACELL 2 AMP BATTERY CHARGER/MAINTAINER

I got this to use with a couple of the GC-1270 12V 7.5AH cells from All Electronics, in my Tennis Tutor 2 tennis ball machine. The charger works great, delivering roughly 2A as advertised and keeping the charge voltage within spec (I don't have the benefit of a recording DVM, but from eyeballing the voltage from time to time it looked OK). A great value!

This is a "bargain" version of a much, much more exspensive charger/maintainer. For long term "float" charging of some kinds of wet cell lead-acid batteries, these can use some electrolyte checking. Bigger riding mower batteries and big cycle/snowmobile batteries seem to take it OK, but the tiny 4 amp/hour battery on my on-off road bike it uses quite a bit of water a month. My $100 unit doesn't do it(of course), but the exspesive unit keeps the big bike's battery happier(less sulfation) by cycling a load on-off. This unit will NOT keep a sealed motorcycle/watercraft/snowmobile battery charged. Yuasa calls for more voltage than these put out, not much, about .4 volts, but that's enough. $78 lesson learned. I think this unit would be fine for a stored car/truck/ tractor/RV/boat battery, but those smaller batteries have always been a little fussy. A decent value, but not perfect for all applications

I don't see why you can't keep it on the generator starter battery all the time.
Although, if you use the genny frequently, it should stay charged just like a car's battery does.

I have a 12v lead acid battery that I would like to run an led lamp I made off of. I am running off a generator year round and was wondering if I could leave this plugged into the wall and hooked up to my 12v battery. Would it keep the battery fully charged and be ok to just leave?


thanks

This is a nice charger, but do not allow the output leads to short; even if it's turned off, it'll blow out! I haven't opened my blown one up to see if it's just a fuse.
