An on board battery charger with 24-volt capability gives you the convenience of charging your boat, forklift, electric scooter, chair lift, golf cart, RV, heavy vehicle, construction equipment, mobility chair, or other vehicle without having to transport the charger. An on board battery charger with maintenance capability can keep your battery fully charged while you’re not using it so it’s ready to go when you are.
An important feature of any on board battery charger that will be mounted on a vehicle is waterproofing. Battery chargers exposed to the elements won’t last very long without being able to withstand the weather. A marine battery charger or boat battery charger is particularly susceptible to corrosion from the harsh marine environment.

How much power do you need? That depends on what you want to use the battery charger for. If you are charging your battery every day for daily use, you need a more powerful charger that can handle deep cycle battery charging requirements.
On the other hand, if you’re storing your vehicle or use it infrequently, a lower amperage on board charger that can charge and maintain the battery at the right charge is probably all you need.
The difference is that powerful battery chargers cost much more, are heavier, and are not typically mounted on the vehicle.
It’s important when choosing a battery tender to buy one of the new smart chargers. A smart onboard boat battery charger will charge your battery and then maintain it at the proper charge level automatically without manual intervention and without overcharging.
We searched battery forums, manufacturer sites, customer review sites, consumer sites, social media, and retail sites to find the most popular and highly rated on board battery tender.
