What to Look for When Buying Deep Cycle Battery Chargers


To buy a suitable deep cycle battery charger, you must check the vital features that a charger must possess. For more details, let’s check out the following shopping guides:

Monitoring Charge Level Capabilities

There’s no denying that nothing beats a deep cycle battery charger that can monitor the state of your battery’s charge level. These versions are particularly helpful in automatically adding more power when they discern that the charge level is critical.

While such deep cycle chargers with monitoring charge level capabilities are slightly pricier, they are convenient and practical options. This charger model is worth the investment if you’re busy or find it inconvenient to regularly check the battery status.

The Size of Your Battery

As for the battery size, you should measure the amp hours that your battery can store. The standard amp-hours seen on batteries is 50 amp-hours. This means that battery size does not solely refer to the physical dimensions of the battery.

Please note that a 50-amp-hour battery requires a 10-amp charger to ensure a full charge in six hours. Furthermore, a 100-amp marine battery will require the same charger to charge fully in 11 hours.

Essentially, it would help to quickly decide which one is more suitable for you if you considered this aspect.

Charging Speed

The speed of the charging process is generally reliant on the total battery capacity and the deep cycle battery charger’s output rating. In general, when you charge low-capacity batteries using a high-amp charger, it will charge remarkably quicker than high-capacity batteries using low-amp chargers.

Therefore, it’s vital to choose the appropriate amps for deep cycle chargers. Take in mind that high charging speed is beneficial when your battery discharges while you’re on the go or when you’re traveling.

The Type of Battery Used

It’s worth noting that some charger options are merely used for specific types of batteries. For instance, a charger capable of charging a lead-acid battery cannot charge a GEL battery. So, if you use the charger to charge your gel battery, the result will be damaging.

On the other hand, some smart chargers are specifically designed to charge both gel and lead-acid batteries, so you have to be careful about that. This example specifies why it’s essential to check your options before buying one thoroughly.

Equalizing Feature

This one is a valuable feature to consider because it is advantageous in making the battery last for an extended period. A charger with an equalizing feature does a great job of stabilizing the battery’s charge, which can help prevent damage brought about by the sulfation effect.

Since an equalizing feature is precious, a deep cycle charger designed with this capability is more expensive. Nonetheless, it’s unreasonable to have second thoughts about investing in one.


Unquestionably, we all prefer to invest in a deep cycle battery charger that is built to last. After all, who would want to spend more on frequent replacements? Due to this, it’s just right that you thoroughly inspect the entire construction of the battery charger you’re buying to ensure extended battery life.

Comparing several customer reviews is a good way of finding more about the option you’re considering. Reading product reviews lets you better assess if the product you’re planning to buy meets your requirements. By reading some customer feedback, you can uncover more about a deep cycle battery charger’s features, capacity, and performance.

Do Deep Cycle Batteries Need a Special Charger


Yes. Deep cycle batteries sometimes suffer from severely low charge levels that obstruct running RVs, electronics, or boats. Due to this, charging the battery backup requires a special charger that can help restore the appropriate voltage of the battery.

When Should You Charge a Deep Cycle Battery

Deep cycle batteries are more likely to discharge roughly 45 to 75 percent of their capacity, but this will, of course, primarily depend on the device’s manufacturer. You can examine the battery’s charge status by using amp-hour meters, hydrometers, or voltage indicating digital monitors.

It’s critical to recharge the battery when they specify a 50 percent charge; however, be sure not to allow them to get below 20 percent to ensure extended service life.

What Amp Should You Charge a Deep Cycle Battery

It’s essential to note that a 2-amp charge rate is purposely for small batteries like the ones we used on snowmobiles, motorcycles, and lawn garden tractors. Therefore, if you intend to charge a larger battery, it will require a longer time, and the battery might discharge at a higher rate than what a 2-amp can supply.

For this reason, we strongly recommend you to charge deep cycle batteries at a greater charge rate, such as six amps or beyond. For all that, it helps to check the specifications of your battery first to ensure the appropriate charge rate.

Is It Better to Slow Charge or Fast Charge a Deep Cycle Battery

Slow charging deep cycle batteries is more recommended than fast charging. The reason for this is because the slow charging method won’t cause any adverse effects on the plates or cells of your battery.

Can You Overcharge a Deep Cycle Battery

As much as possible, you should not overcharge your deep cycle battery. Overcharging your battery can be dangerous and damaging. The three main problems that can emerge from battery overcharging include temperature damage, increased fluid consumption, and corrosion.


Ultimately, before you can end up buying the best deep cycle battery charger, you have to thoroughly review the vital features that a reliable and functional charger must possess. Fortunately, deciding on the must-have features and functions of a battery charger shouldn’t be much of a concern if you have enough knowledge of what to look for.

Hopefully, by going through the product reviews and buying tips shared in this article, you can intelligently decide the most suitable option for your requirements. With plenty of reliable and technically advanced choices available today, for sure, you can get the right match for your camper, RV, electronics, or boat.
