Solar Deep Cycle Batteries For Sale

Post by rjj04 » February 8, 2019, 11:00 am

3 Globatt Inva 12V 150Ah batteries
Bought 2015 from Amorn, used in 48v config, 3 banks, 20+KWhs
Used off-grid for a couple of winter seasons, otherwise in back-up mode only

Off-load/Off-Charger (2 days off charger) SOC 12.66V, 12.68V, 12.65V (ie >95% remaining capacity)

State of charge (SoC) of a lead-acid battery, expressed in %, is the ratio of the remaining capacity (RC) to the full charge capacity (FCC) (see Fig. 1). FCC is the usable capacity at the present charge or discharge rate and temperature.

SOC - Voltage Measurement Table
Capacity Sealed or Flooded Lead Acid | Gel battery | AGM battery
100% 12.70+ 12.85+ 12.80+
95% 12.64
90% 12.58
85% 12.52
80% 12.46
75% 12.40 12.65 12.60
50% 12.20 12.35 12.30
25% 12.00 12.00 12.00
0% 11.80 11.80 11.80

Will take specific gravity readings of each cell if serious
Example of unit...

$3,250 THB per battery
Note: this is a take it or leave it price... I loathe haggling, if not interested at this price then don't ask me
for a discount... I'd rather just let them sit on my custom built distributed charger :)

If you haul these things home, they weigh quite a bit, and test them yourself for a couple of days and are not
satisfied, then bring them back and I'll give you back your money (assuming you haven't damaged them somehow
naturally). I'm not going to your place to pick them up though :)

Note: anybody "SERIOUS" about buying other solar items (chargers, GTIs, off-grid inverters) or even my whole solar system (as we are moving back to farangland) drop me a message.

Sorry to hear that you are leaving. I'd like to buy your batteries but my problem is that my ten year old 12 volt FB deep cycle batteries have shown no signs of weakening and I have no room because of too much shade to build another system.

Thanks glalt
I just hope grandpa will not screw up and actually stop by and top up all my batteries from time to time or it will be quite a $$$ hit :(
