Hi guys, I can get these batteries locally. Used ones are so cheap they are half the price of new ones very tempted
. what do you guys prefer on these battery setup for a 12v system single or 2 x 6v in series? budget, space etc don't matter.
My solar setup will be for now
one >200 solar panel
12v trojan battery single or 2 x 6 in series?
morningstar mppt 45A
morningstar 300 pure sinewave inverter
Let me what you guys think, im going to pick the battery soon.

Re: Trojan T1275 or T-105
i would say either battery may work. bad thing is you don't know the real condition of those used batteries. some of these things can help you in determining viability as if it is no good it won't matter how cheap it is.
you need to see the date on it to determine its age.
you need to look into the electrolyte and if murky it may be bad. also the levels and specific gravity have to be observed.
how long ago was it charged and was it float charged?
what were they used for before?
what kind of voltage you see from them too as getting more than 1 battery means trying to match voltages and specific gravities to keep them balanced with each other. -

Re: Trojan T1275 or T-105
For sure I'd be VERY wary of used batteries and unless you truly know their life history and carefully check each cell for SG and each battery for resting voltage, would never pay more than their scrap value, because unfortunately that's usually what used batteries are. Scrap.
