Need batterys.
Had 12 volt duracells DC 24. Served me OK. lasted 6 years. They were january 2014 matched pairs.Cell went dead on neg side battery I Run 1100 watt inverter and do the coffee maker thing and toaster...
Forum Discussion
There are many very technicial pages on the relationship between internal resistance, Capacity in amp hours and recharge but unless you have a degree in electrical/electronics engineering .....
The bottom line is the bigger the battery the more amp hours the lower the resistance.. HOWEVER for GC2 and bigger this is not the limiting factor. My Converter is 80 amps. I have seen Inverter/chargers that can hit 100.. Xantrex recommends no more than 0.30 C recharger rate (Where C is the 20 hour Amp hour capacity) so for my G-20s (230 amp horus (that's 69 amps. add in a bit more for the starting battery *(73AH so it can take around 22 amps) and the 80 is right.
I"ve added a bit more so I can eat it all
Recharge time is a function of State of discharge, converter size, actual charge rate up to around 90% SOC.. then 2-4 hours to finish.
