I have no gravity tester how long for a 10 Ah battery

Its sitting for the recommended one hour post acid fill.
I have a 1 amp charger so is that min 10 hours charging time?
Batt Instructions ask for .5. to .75 as ideal.
My AGM batt got hot swelled up and died yesterday.
I was far away from home and was shocked at all the happy bikers passing me by.
Such a high percentage love to wave in a spirit of lazy fake comradely but would not stop if you were dying.
It was a nice day to push a bike though. Nice guy came out of his yard and helped me push the bike to his garage.
He gave me a chair and offered me a cold beer.

You have a serious overcharging problem, fix it first or the next battery will do the same.

The AGM was abused by three over night head lights left on scenario.
It would not take a full charge this spring topping off to about 90 % of full charge.

The AGM popped its vent so its ruined but my charging output voltage is in spec as per the VM. I do not recall the number though.

If you're following the "BMW battery " write up, you can do it with a smaller charger. While the rate of your charger gives you an estimate of charging time, I think the battery voltage is the metric to watch.

I charged my new battery on a weekend. Just plugged it into the charger and check the voltage every hour or so.

But if you managed to kill an AGM battery, you definitely have other issues.

Thanks.What is ythis BMW Battery writeup.
I have been on at 1 amp for three hours and have about 13.4 volts
at least 2 to go I think from the instructions that I overlooked which were in the bottom of the box.
