Even the best PWC battery will lose its juice over time. The best way to combat this and make it last as long as possible is with a good battery charger.

In this post, we recommend a couple of our favorite jet ski chargers. There’s an awesome regular charger called the ‘Battery Tender Jr’ and also a quality solar battery charger for times when a power outlet is hard to reach.

Our Recommended PWC Battery Tenders

In no particular order, these are the battery chargers that we recommend. It really depends on where you keep your watercraft stored as to which one is best for you. We explain all in the next couple of minutes.

Battery Tender Jr

Currently, the Battery Tender Jr. is the top jet ski battery charger available. Of course, there are other options, but none of them really compare.

For the most part, this jet ski battery tender is pretty simple to use. It does a great job at keeping batteries fresh and is the perfect option for winterizing a jet ski.

It works with just about any battery, and it’s relatively inexpensive. There are a few different models, but the lower mp versions are preferable. Ideally, you want to charge the battery slowly at less than 2 amps. Overcharging the battery is just as bad as letting it go flat so a jet ski charger that does the job slowly is a winner.

Besides being a really dependable and effective jet ski battery charger, the Battery Tender Jr is also great value for money.

With almost 10,000 positive reviews, this is without a doubt one of the best trickle chargers on the market.

Solar Battery Tender


Solar charging goes hand in hand with trickle charging. A solar charger slowly charges a battery when it is not in use to maintain its charge over long periods of inactivity. This will help prevent your jet ski battery from dying

It’ll slowly and carefully charge the battery during the daylight hours each day. The battery will lose a little charge each night and then this battery charging cycle will repeat itself day after day. This is what the battery wants and what will keep it running well.

This solar-powered charger from Dellran is another great option that will help preserve your battery and stop you from buying a new one every season!

To be honest solar chargers are really practical pieces of kit that are really simple to use. Just plugin or pack away! They’re really easy to set-up and don’t need to be plugged in (which can be a huge headache sometimes). They’re also better for the environment (and your wallet) as they use free, renewable energy. They actually don’t need any direct sunlight either and will work just fine when it’s cloudy too.

This model is specifically designed to work with vehicle batteries. It’s actually completely waterproof too, which makes it well suited to jet ski charging.

It uses a special microprocessor to limit the voltage and avoid over-charging of the battery. It maintains a small voltage through the battery to keep it “energized” when not in use. 

It’s a great option for those that don’t have a power outlet readily available.

What does trickle charging mean?

During off-seasons, it’s advisable that most batteries be trickle charged and stored in an area not exposed to extreme cold.

Trickle charging a jet ski means removing the battery from whatever housing it’s in. Once the battery is out of the jet ski it should be attached to a trickle charger and stored in a cool, dry, place.

Trickle charging jet ski batteries is one of the easiest ways to get the most use out of it. As the name suggests, trickle charging slowly charges your battery over an extended period without overcharging it.

A Final Word on PWC Battery Chargers

Proper maintenance of your battery is not only inexpensive, but it’s also easy to do. Simply investing in a good battery and PWC battery charger is a great way to prevent problems later on.

If you’re lucky enough to be able to use your jet ski regularly all year round then you probably won’t have any issues, but for those of us that need to put our watercraft in storage for part of the year, proper maintenance must be done.

Make sure you keep your battery topped up and never let it drain completely or overcharge. A slow, steady charge like that from a jet ski battery tender is perfect.

If you have access to a power outlet then a regular charger is an option. However, a solar PWC battery charger is even better for a variety of reasons:

  • It uses renewable, free energy
  • It can be used anywhere
  • It’s portable
  • It’s quick and easy to use

Obviously, being solar powered it will work much better in places with more sunlight, but it should still work on overcast days too. The choice really comes down to where you keep your jet ski stored.

Be sure to follow these tips, and your jet ski will run just as good in April as it did in August.
