Steven in Sales has published another useful guide and this one address battery chargers, charging tips, proper amps, and voltage. Let’s dig in! According to Steven, the best jet ski battery charger will be a 12-volt smart charger that charges at a max of 2 amps. His top choice of battery charger’s is the NOCO Genius2, 3-Amp Fully Automatic Smart Charger. It has the right amount of charge, and a built-in maintainer that automatically turns on and off as needed.
The Battery Tender Plus 12V Battery Charger and Maintainer is his second-place pick. It’s super simple to use and easy to store and with 1.25 amps, it has just enough amps to charge a battery at a good speed. If you’re off the grid or store your ski in an area without a power outlet, a solar charger is in order. When charging a PWC battery, charging from .75 to 2 amps is a good range for a charge.
Charging at over two amps is too fast and will cook a small jet ski battery. It will take about 12 hours to get an empty battery up to a full load. It’s good to keep your battery on a charger, especially if you don’t ride much. A well-charged battery will last longer. One last thing; do not jumpstart a jet ski battery with a car or a truck unless you want to replace your electronics.
