Boat Battery Chargers That Charge Two or Three Batteries Separately

January 19, 2021 9:15 pm Published by Leave your thoughts

Your boat probably comes with more than one battery—a “house” battery for your on-board systems, and a battery or two to power your engine. After a day out on the water, your boat batteries will need to be recharged, and sometimes those batteries have different charge types. Luckily, there are single boat battery chargers that can charge two or three batteries separately, so you don’t have to lug around extra equipment.

Here’s what you need to know about chargers for multiple boat batteries in Houston, TX.

What kind of charger do I need?

Your charger size depends on the size and type of battery your boat uses, as well as your AC power—is it continuous or intermittent? If your boat spends most of the time at the dock hooked up to a power source, you can get away with a smaller charger. Generally, look for a charger that can handle all of the DC load plus about 10 percent of the batteries’ amp-hour capacity.

On the other hand, if you spend most of your time out on the water, you’ll want a charger that can recharge all the DC power load plus an adequate charge rate. You can determine the charge rate by dividing the amp hours available by the hours available. Of course, depending on the battery, the maximum charge amperage will vary. They typically range from 25 to 40 percent.
