2 x 12 volts or 2 x 6 volts batteries?
Hi, I am about to replace my house batteries. I was reading that connecting 2 x 6 volts in series will double the voltage but not the amps. Connecting 2 x 12 volts in parallel will keep the same 12 vo...

One of my 6 volt AGM battery failed, it read 4.2 and the other reads 6.4. I need some batteries to get me going until I am in USA to buy new ones at Costco or Sam, none available in my Costco. I have two old acid 6 volts, still useable but not very strong, that I want to pair with my 6 volt AGM.
I was planning a tempory installation of 3 x 6 volts to get more juice. Two in parallel and one in series with the two parallel, isn't it possible, I am just about to connect the setup!
NO!
ok it can be done but there is no point really. Or maybe there is if the two old batteries are low on capacity you could parallel them and place in series with the good AGM. Worst case you will over work the AGM and have to remove it and place the two wet cells in series.
Probably better off to just put the two wet cells in series from the get-go and save the AGM for the core charge. They may benefit from an equalization charge if they have been sitting.
