How Long Does It Take To Charge a Marine Battery?

 How long does it take to charge a marine battery? That's what we're going to take a look at today.

Most marine batteries don't have clear instructions on how long they should be charged which is quite annoying. It leaves the user having to guess how long they should charge it.

In this article, we're going to give you a general guideline to help you understand how long yours should be charged.

Something to note is that all batteries have a different amp capacity.

This means it would be quite hard to give you a general guideline of how many hours it takes for a marine battery to charge as there are so many factors.

Some of the factors include:

• How many amp-hours the battery has

• How many amps the charger has

• Hold functional the charger is

How Long Does It Take To Charge a Marine Battery?

Most marine batteries require 80-100 amp hours to be fully charged.

Common marine battery chargers have 2-10 amps. You can then divide the amp hours by the amps to get the time it will usually take.

For example, if a charger has 10 amps and needs to recharge a marine battery with 80 amps, then it will take around 8 hours.

You must check how many amps your charger has first, as well as the amp hours of the marine battery. Otherwise, you might end up overcharging it which could damage your battery. 

Or, you could also not charge it anywhere near its capacity, which could be quite annoying too.
