Hello...
I have a 12V 2.8Ah sealed lead acid battery... and a battery charger
that can be set from 50 mA to 300mA.
What should I set the charger at?
Not too sure if the battery is any good, but I thought I might try and
recharge it to see if I could get some use out of it. It had been a
backup battery in an alarm system.
Thanks
10 hour rate is generally reckoned to be safe 'forever' so 280mAh.. or
go for a 1 hour charge at 2.8A.
