About the VoltKeeper
Will it work with my car battery?
Yes. It works with 12V car batteries, including standard, AGM, EFB and start-stop batteries, as well as lithium (LiFePO4) batteries.
Do I need to take the battery out of the car?
No. Just open the bonnet, clip the red clamp on the red (+) terminal and the black clamp on the black (–) terminal.
Can I leave it connected overnight?
Yes. It stops by itself when the battery is full and then keeps it topped up, so you can leave it on for days.
How long does it take to charge?
It depends on how flat your battery is. A low battery usually charges in a few hours. A very flat one is best left overnight.
Can it fix a battery that keeps going flat?
Repair mode can help tired batteries that keep losing charge. A battery that's damaged inside may still need replacing.
Which plug does it have?
Choose the EU (2-pin) or US plug when you order. For a UK socket, use a standard travel adapter.
