AGM 140 Ah Solar Battery Supply Battery 12 V Battery Consumer Battery

Good battery

Spec list3 x 12v AGM HLB800 95AH Halfords1 x 12V AGM Pro Solar 140AhWired in series then parallel to equal 24VPoor charge hold. My 24v solar battery array has started performing extremely poorly. I have omitted the cheap 140Ah battery, the array is performing better without the battery!My guess would be cheap recycled batteries with an equally poor sticker (which incidentally is falling off)

I received two of these batteries hoping to have a significant storage of electricity in my van. Reality is that these are poorly manufactured batteries that struggle to hold their charge. My solar system was working perfectly with a branded 65 Ah AGM battery, now i see the voltage going from 12.7 (full charge after a night of charging) to 12.5 after two hours. The batteries are wired in parallel, which means that during that time they lost about 20% of their total charge charge (which should theoretically be 280 AH), with nothing plugged in.The seller offered a possbile refund after they have been sent back to them, then to the manufacturer who should check them and let me know if they are really faulty or not. Since i don't really want to go through this time consuming process (and honestly, i don't trust neither the vendor or the manufacter), i prefer to keep the battieries and use them until they die, which will probably be very soon.Don't make my same mistake and avoid this item.
