Will not buy again
Two 135 amp batteries lasted in my motorhome just around 2 years only running a 100L fridge thats all before completely failing last night,.always charged by 600 watts solar and mppt controller along with alternator.
Battery works just...
I brought the 140ah battery a few months ago, I have excellent dual Battery system setup that runs other batteries well. This battery with 140ha will get fully charged and will last about 6 hours absolutely max with just a 20lt fridge. I now use a 100ah that will last 3 days easily with a fridge freezer, many lights and phones/speakers charging. Wouldn't recommend
No customer service
Tried to contact many times re the watch power system settings no replies. The solar installer does not deal with them any more as he had problems getting warranty work done. To date the system has worked but I am unable to check settings.
Questions & Answers
After a 1l12v 140 ah agm battery for a camper trailer. Needs to run a 96 litre fridge and lights. Is the Giant 140ah battery worth buying??
Hi, so what would be the unloaded drain rate in volts or amps?
I’ve got two 140 amp batteries in parallel wondering what maximum current would be for charging
I *think* maximum charging current is about 20-25% of the available supply current, so you'd be pretty safe at 28 amps x 2 because in parallel = 56 amps. The batteries will still charge at lower current, but will take a little longer.
Google is probably a better source of information rather than asking on Productreview.
