Before you buy
Can I use this on both motorcycle and car batteries?
Yes, within the recommended capacity range. Ampmatic automatically adjusts current to suit the battery’s size and condition.
Do I need to disconnect it once the battery is charged?
No. It switches to maintenance, checking the battery periodically and supplying additional charge when needed.
Can it recover a deeply discharged battery?
It can attempt recovery from as low as 0.5V. A deeply discharged 12V battery requires manual confirmation following the instructions. Recovery depends on battery condition and cannot repair permanent damage.
