Shouldnt they be kept in storage at 50 per cent charge ? Any feedback greatly appreciated. AGM batteries have a very low self-discharge rate. About 1% per month. What you have does not sound right to me. 8 months on the shelf should not have left the batteries totally flat. The batteries may still work and take a charge, but their capacity and service life have been affected. Personally, I'd be asking for a refund. I would not accept a replacement, because at this point, what's to stop the dealer from charging up another set of flat batteries and sending them as replacements. They will arrive seeming good, but they will be the same as what you have. He's already lied to you about this being "normal". It isn't. CWM thanks the batteries read 10.5 v and 11.5 v respectively is there any way to tell how old they are ? could i contact the manufacturer with the serial numbers ? |

Some ignorant battery sellers just add acid and never give the battery an initial charge. They suffer from this old wives tale that batteries are "dry charged." There is no such thing as dry charged. Any lead-acid battery needs to have electrolyte added then it needs to sit for about half an hour then it needs to be topped off to the upper limit line. Then it needs to be placed on a charger that runs at 1/10th the amp hour rating and it needs to sit there and charge for 24 hours min. If a battery never gets this proper initial charge it will never perform up to its specs and it will have a shorter working life. Send the damned things back and stop payment. Hopefully you used a credit card. Wilbur Hubbard |
