Some Surprisingly Easy Ways To Maintain 36V lithium marine battery

The 36V lithium marine battery is an important component of your boat. It powers your bilge pumps and other electrical devices. You need to take care of it to make sure that it works well for as long as possible. Here are my tips for maintaining a 36V lithium battery:

Charge Regularly

The battery should be charged after each use, but also at least once a month if it’s not being used. If you don’t use your boat for an extended period of time (a week or more), charge the battery anyway–even if it’s only partially discharged.

The 36V lithium battery should be charged to at least 80% of its capacity and then disconnected from power source when fully charged. This will help maintain the life of your lithium-ion cells by reducing stress on them during charging cycles and preventing overcharging which could lead to unwanted chemical reactions with electrolytes inside cells.

You should also check your temperature gauge regularly because extreme cold or heat can cause damage when charging; therefore, we recommend storing it indoors in temperatures between 50F (10C) and 90F (32C).

Avoid Overcharging

Overcharging your battery is a big no-no, as it can lead to some pretty serious damage. Overcharging can cause the battery to overheat and vent gas, which is why it’s important that you have your charger set up properly. If you’re using a simple plug-in charger or one that plugs into an outlet, make sure that the device has its own fuse or circuit breaker protection system that will shut off power in case of an overload situation.

Using The Right Charger For Lithium Marine Battery Is Important

Using the right charger for your 36V lithium battery is important. You need to make sure that you are using one that is compatible with your battery and will charge it properly. There are many different types of chargers on the market, but they all have similar features in common.

The first thing you should look at when choosing a charger is its capacity. The capacity refers to how much electricity can be stored in each cell of your 36V lithium battery (amp hour). If you have an 18Ah battery, then this means there are 18 amp-hours in total within it–or about 1 hour’s worth of power per 100% full charge cycle!

Keep It Dry

The first and most important thing to do is to keep your 36V lithium marine battery dry. This means that you should avoid getting it wet in any way, especially during charging or use. If your boat is stored outside, make sure the battery is stored inside a waterproof container so that it doesn’t get rained on or snowed on (if you live in an area where winter brings snow).


We hope this article has helped you learn about how to take care of your 36V lithium battery. You may not think much about it, but it’s important to keep your battery in good condition so that it can last as long as possible and perform at its best.
