DescriptionThe AL 501 automatically switches off when the battery is fully charged to prevent overcharging too. Two-stage charging means the battery is first charged at a constant current up to a predetermined voltage limit. Then, the charger switches over to charging at a constant voltage before the current reduces itself automatically until charging is complete. A built in cable tie with Velcro strap on the back means you can wind the cable to the charger to reduce its length. Plus, this charger can be wall mounted for space saving storage.AK System charge times (80/100%)AK 10 battery25 mins45 minsAK 20 battery30 mins50 minsAK 30 S battery35 mins60 mins AP System charge times (80/100%)AP 20 battery25 mins40 minsAP 200 S battery25 mins35 minsAP 30 battery30 mins50 minsAP 300 S battery30 mins45 minsAP 500 S battery40 mins55 minsAR 2000 L battery120 mins160 minsAR 3000 L battery180 mins230 mins
