My Stihl MSA AP300 battery had gone flat, i suspect as left sitting idle on cold shed shelf it had dropped to less than 6 volts and would not recharge in cradle.
I explored some yotube vids where operators hooked up MSA battery's with jump start wires and rebooted dead battery.. But as i could not work out which blade terminal was + or - and bit fearful of fizz flash or bang! I took it to a specialist battery store the chap checked tested & put it on his (defibrillator) battery charger and rebooted it.
Yay brought back to life this saved me some bucks.
