What onboard battery charger do I need?
To determine what amp charger you need, you’ll need to perform some basic math. Let’s say that you have a Group 24 battery that has an 85-amp hour rating. Multiply “85” by 10%, and you’ll get “8.5.” This means that to recharge this battery, you’ll need at least an 8.5-amp charger.
Do marine batteries need a special charger?
Do You Need A Special Charger For A Marine Battery? The short answer is: no. However, you must use a charger that matches your boat battery’s chemistry and voltage.

Can you leave an onboard battery charger on all the time?

How many amps do I need for a marine battery charger?
Choose a charger with a rated output (amperage) that’s about 10 to 15 percent of the combined batteries’ capacity (ampere-hour or Ah). So if you need to recharge two Group 27 batteries (2 x 105 Ah = 210 Ah), a rated 20-amp charger is a good fit. A typical dual-bank, 20-amp charger has a 10/10 per leg configuration.
Should you disconnect boat battery when charging?
No need to disconnect the batteries. If you have a battery switch, turn it off, if not, don’t worry about it. A word of caution, if you run the battery down playing music or with lights for hours, the charging system on the boat will not bring the battery back up sufficiently in a short boat ride.
