Spend More Time On The Water With A Lithium Deep Cycle Marine Battery

Can you charge an ionic lithium battery with a 12V charger meant for lead acid batteries or other battery types? It’s possible--but not optimal.

You may end up with a snail’s pace charge, an incomplete charge, or no charge at all. Not to mention the fact that an incompatible charger can damage your battery. It may also decrease its performance and lifespan over time.

Here’s why it’s important (and beneficial) to use an ionic charger with ionic lithium batteries:

  • OPTIMIZED: We’ve built our ionic 12V chargers with lithium batteries in mind. They are optimized for LiFePO4 batteries, producing a fast, full charge every time. 

  • CCCV: Our chargers provide constant current, constant voltage (CCCV). They’re designed to maximize the life of your lithium battery.

  • SMART: An ionic 12V charger stops charging once it reaches 14.6V. This smart function protects your battery from damage.

  • LIGHTWEIGHT. Save your back and skip the heavy, cumbersome chargers. Our smallest charger, the 12V 4A, weighs only 4.5lbs (2.0kg). Our largest ionic charger, the 4 Bank 12V 10A charger, weighs just 11 pounds.

  • SMALL. Never bulky, our chargers can go where you go. Our largest charger, the 4 Bank 12V charger, measures 12in x 9.5in x 2in.

  • HIGHEST QUALITY. Lithium batteries are an investment, so you want to protect them the same way you would protect your laptop with a sturdy case, or your car with frequent tune-ups. Our high quality 12V chargers ensure your batteries continue to function at their best, even as time goes by.

Two Main
Types of Chargers

There are two types of chargers that you can use for your 12v batteries: single and bank chargers.

If you want to charge just one battery, choose a single charger. If you want to charge 2,3, or 4 batteries at once, pick a bank 12V charger. You can also wire a single charger in parallel to provide additional charging current to large battery systems.

Chargers for Different
Battery Sizes

Chargers also differ by amp rate. For example, a 12V 4A battery charger will charge a 12 volt lithium battery at a rate of 4 amps per hour. This means that it can fully charge a 12V 12Ah battery in 3 hours.

When choosing a charger, keep in mind that the higher the amp rating (A), the faster charge you’ll get. However, make sure the amp rating isn’t higher than the amp hour rating of your battery. Using a charger with an amp rating that is too high can damage your battery.

FAQs

What’s the difference between a 4A, 10A, and 20A charger?

The “A” stands for amp rating. This rating refers to the amount of power your charger will put into your battery per hour. So a 4A charger will charge at a rate of 4 amps per hour. A 10A charges at a rate of 10 amps per hour, and 20A at 20 amps per hour. It is best to choose a charger with an amp rating that is less than (about ⅓) the amp hour (Ah) rating of your battery.

How fast will my battery charge?

Here’s how to figure out how fast your lithium battery will charge with our ionic chargers. Take the amp hour rating of your battery and divide it by the number of amps of your charger. For example, a 12V 4A charger will charge a 12V 20Ah battery in 5 hours.

Can I charge other types of batteries with an ionic 12V charger?

Yes, you can charge lead acid and AGM batteries with our ionic chargers. However, they are most ideal for lithium batteries. Some functions, such as the charge level and time to charge display on our 4 bank charger, will only work with lithium batteries.

Can I charge lithium batteries and lead acid batteries at the same time?

Yes. When using the 4 Bank 12V 10A charger, you can combine battery types. For example, you could charge 3 ionic 12v 50ah trolling motor batteries and an AGM starting battery simultaneously.
