A jet ski battery charger or battery maintainer is a must-have item for any PWC owner, or else you might find yourself constantly buying new batteries. Connecting your jet ski battery to a maintainer is part of the winterization process and ensures proper longevity of any battery. You never want to jump a jet ski battery with a car battery – so don’t let your battery die!
Batteries die when they are not powered on for long periods of time (like being docked for winter). Using a battery maintainer trickles the battery to keep it “alive” for extended periods of time.
There are many effective and affordable options for battery chargers. We will be covering some of our top picks.
The best jet ski battery chargers are:
- MarA Wireless Smart Charger
- Stanley Smart Charger
- Extreme Max Battery Buddy
- Battery tender Plus

This is our top pick. We love this charger/maintainer because of its versatility and convenience. Not only can both charge and maintain jet ski batteries, but it can also also be controlled via a smartphone app. While your jet ski is docked or in storage, you can monitor your battery with the app.
With a cold mode setting, this charger is perfect for winter storage (down to -4 degrees F). With 12v and up to 4amp, you are able to also charge car batteries, motorcycles, boats, and more. It is capable of charging and maintaining both Lead-acid batteries and Lithium(LiFePO4) batteries. It uses a smart charge technology to read your battery, taking the guessing out of the equation. Never worry about damaging your battery with this charger!
Some other features include:

SOLPERK Solar Charger
Solar-powered jet ski trickle charge battery maintainer.Buy Now on Amazon
This is one of the most affordable options at around $35, but it is still really cool. Though less versatile, this charger is completely solar-powered. Although it won’t come in handy if you need to jump a dead battery, this clean energy device will keep your battery maintained during winter months without the need of a power source – it just needs sun!
It’s important to emphasize this is strictly a battery maintainer. You don’t want to use this to charge your batteries. It is not a fast charger. That said, if you just need an effective and affordable battery trickle maintainer to ensure the longevity of your battery – this is the one.
