Want to know how to properly charge a deep-cycle battery? You've come to the right place!

So you took a chance and invested in a 12v deep cycle battery. You can't wait to spend time on the water with your trolling motor and fishing gear. But if you want your battery to last a long time, you'll have to do some work to keep it running smoothly.

Of course, if you have lithium deep-cycle batteries, your list of maintenance tasks is short. Almost as short as Santa's list of gifts for naughty children. They don't need to be cleaned and topped up with electrolytes on a regular basis like lead-acid batteries.

However, there is one thing you must do with any battery - even a lithium battery. You have to charge them the right way!

Why you need to charge your batteries correctly
Why does the way you charge a deep-cycle battery matter? Well, the right way to charge your batteries can have an impact on their performance and range.
For lead-acid batteries, overcharging them can ruin them. Leaving them in a partially charged state can also have a real impact on them.

Fortunately, marine lithium batteries don't have these contraindications. You can use batteries at more than 50 percent capacity without damaging them. And you don't need to recharge them as soon as the charge runs out. This is very handy when you get home from a fun but tiring day at the lake.

But there are a few things you'll want to keep in mind when charging deep cycle batteries, even if they're ion lithium. Keep reading to learn how to charge your deep cycle battery the right way!

Battery Charge Cycle.
You can charge a deep cycle battery to full capacity many times over the life of the battery. You can delete it for a long time and then charge it to full capacity multiple times. You'll usually start with a 100% charge and then deplete it to between 20% and 50% of capacity. Then recharge to 100%. No problem.

The normal depth of discharge of batteries also affects their life. To make a battery last longer, you need to charge it up to 50%, and often. Repeated shallow discharges (5%-10%) on deep cycle batteries shorten their life.

A good 12v deep cycle battery can be depleted and then recharged to full capacity. You don't have to be very conservative with your batteries when you're on the water. Drain them and when you get back to dry ground, charge them with a LithiumHub charger to restore them to full capacity.

Choosing the right deep cycle battery charger.
It goes without saying that the best chargers for deep-cycle batteries are made specifically for their type. That said, a LiPo charger will charge LiPo ion batteries better.

Of course, it is possible to "mix and match" battery types and chargers. But you run the risk that the charger may reach a voltage level that the battery can't handle.
This could damage your battery, or at the very least, you will see an error code and your battery will not charge.

Also, keep in mind that the right charger will help your battery charge faster. For example, lithium-ion batteries can withstand higher currents. They charge much faster than other types, but only when paired with the right charger.

So, how do you choose the right charger?  read the description of the charger. It will detail which type of battery(s) you can use it to charge. For lithium deep cycle batteries, we recommend using ion single chargers and ion bank chargers. These chargers are for LiFePO4 marine batteries. They are smart chargers. They charge at a steady rate and stop charging when the battery reaches full voltage. Some models can also be used to charge lead acid and AGM batteries.
