The Best Solar Battery Maintainers –Boosting and Preserving Your Batteries with Solar Power

Using a solar battery charger or a solar battery maintainer is one of the easiest ways to keep a battery topped up and prevent it from becoming fully drained.

Solar battery maintainers connect directly to a battery with battery leads, or in the case of boats, cars, and RVs, they can also charge the battery through a 12V cigarette lighter outlet inside the vehicle. Unlike traditional battery maintainers, which must be plugged into an AC wall outlet, solar battery maintainers use solar technology to boost and trickle charge batteries with clean solar energy.

For those that spend time in remote areas, such as off-road enthusiasts, RV adventurists, and campers, having the ability to charge your battery using electricity that is generated from sunlight can be incredibly valuable. They are extremely helpful in emergency situations, as well as being practical products for preserving the lifespan of solar your battery. If you are running a full off-grid solar power system, a solar battery maintainer can also be used to keep your battery bank fully charged, which will ensure you always have access to a reliable source of power.

To help you choose the right solar battery maintainer for your needs, we are going to go over some of the best products on the market today. We will also explain why solar battery maintainers are so useful and what features you should take into consideration before you purchase one. We will also recommend some high-quality deep cycle solar batteries you can use if you are unsure where to start with solar power.

What are the Benefits of a Solar Battery Maintainer?

If you are wondering if it is worth investing in a solar battery maintainer, consider the following benefits: 

  • They Can Prevent Your Battery from Dying – If you are relying on a battery to start your vehicle, it almost goes without saying how important it is to prevent that battery from dying while you are in a remote location that lacks access to grid power. Solar battery maintainers use solar panels to generate electricity from sunlight, which means they do not rely on a grid network to charge your batteries.

  You can avoid emergency situations by connecting a solar battery maintainer    to your vehicle’s battery. This is particularly important if you draw power from    your vehicle’s battery to charge and power electronics and appliances, as is      often the case with boat and RV batteries.

  • They are Completely Free to Operate – Unlike traditional battery maintainers and chargers that use electricity that is drawn from the grid, solar battery maintainers use clean solar energy, which costs you nothing and does not contribute to your carbon footprint.
  • They are Versatile Devices – You can keep a solar battery maintainer in your RV, boat, or camper van to ensure your battery is charged while you are away from the grid, or you can use one to keep the battery bank of your off-grid solar power system fully charged. Any device that relies on a battery can be charged using a solar battery maintainer, which means it is a versatile device that you will be able to get plenty of use out of.

What to Look for in a Solar Battery Maintainer

The following are some of the key features you should look out for if you are in the market for a new solar battery maintainer:

Charging Capabilities:

The key to a good solar battery maintainer is the ability to charge batteries in a variety of ways. You should have the option to connect the maintainer directly to the battery using standard battery leads, or directly into a 12V outlet inside the vehicle. The best solar battery maintainers and chargers will also feature a variety of other charging ports, so you can use them to charge portable electronic devices. These solar chargers and maintainers almost act as emissions-free solar generators that can be used to charge any number of electronic devices, not just vehicle batteries and power banks.

Safety Features:

The best solar battery maintainers have integrated safety features that protect your battery. Overcharge protection, automatic shutoffs, and temperature controls will all keep you safe and protect your batteries from unnecessary degradation.

Sturdy Construction:

There are plenty of poorly-made solar maintainers on the market today, so it is important to choose one that is made to a high standard. A high-quality solar battery maintainer will be built from durable materials, so it can actually withstand regular use, even in harsh conditions. If you are planning to use a solar battery maintainer with your boat or RV, choosing a waterproof model will also help extend the device’s lifespan.

The Best Solar Battery Maintainers

Now that you understand what they are used for and what sort of features you should look out for, we can go over some of the best solar battery maintainers on the market today.

  1. MaxOak Bluetti EB240 Solar Generator 

The EB240 is one of the best-selling solar generators on the market for a number of reasons. It has its own built-in battery that has a storage capacity of 2,400Wh/1,000W, which makes it the perfect option for those that are looking for an all-in-one device.

It can connect directly to a battery to act as a battery maintainer or charger. A built-in MPPT charge controller allows you to connect the unit directly to solar panels, so it can act as a portable solar generator. Dual AC power outlets are capable of supplying 1,000W of continuous power and a 1,200W surge protector protects any connected batteries or electronic devices.

A DC 12V output port is ideal for those that are looking for a battery maintainer they can connect through their vehicle’s cigarette lighter outlet. In terms of the unit’s other charging capabilities, a PD Type-C output port and four USB outlets mean you can use the device to take a significant power burden off of your vehicle’s battery.

  1. EcoFlow - Delta 1,300wh Portable Solar Charger and Generator

Another multi-use solar battery maintainer is the EcoFlow Delta, which also offers a high-capacity internal battery, a 1,800W pure sine inverter, and a variety of charging ports.

What we liked the most about this unit is its impressive one-year shelf life, which means it can be left charged for emergency situations, or taken on lengthy trips as a source of backup power. An LED display screen provides charge input and output information, so you can quickly check the status of any battery you are using it to trickle charge.

Like the previous unit, it also features a variety of charging ports, including AC outlets, UBS ports, and a 12V power outlet.

Other Popular Solar Battery Maintainers:

Given that there are now so many solar battery maintainers on the market, it can be confusing knowing where to start. While we would always recommend the two solar generators highlighted above, it is worth explaining some of the other options.

The Ego Nexus Portable Power Station is one of the more popular items on the market and we recently offered our Ego Nexus Complete Review, which is a worthwhile read if you are considering this product.

You will also find a wide variety of miniature solar maintainers that can be mounted with suction cups through Amazon and other retailers. While these products are very budget-friendly, they rarely generate enough electricity to properly maintain the charge of a high-capacity battery.

Instead, we would recommend going with one of the larger solar generator units and pairing it with a foldable or flexible solar panel that you can lay out when you need to charge your unit’s internal battery.

Deep Cycle Solar Batteries

If you want to get the most out of solar power, you should always pair your solar panels with a reliable and high-capacity deep cycle solar battery. These batteries can withstand the repeated charging and discharging that occurs with solar power, which means they will be less dependent on a battery maintainer to stay charged.

We encourage you to take a look at our Deep Cycle Solar Battery Collection, as we carry a wide variety of sizes and voltages from some of the best manufacturers in the industry.

For those that are looking for an affordable option, we would highly recommend the BattleBorn 100Ah 12V LiFeP04 Deep Cycle Battery. This compact battery is compatible with a variety of systems, including marine, RV, van, and off-grid. It has an impressive life expectancy of nearly 5,000 cycles and is safe enough to be installed indoors. Given that it also is capable of holding a full charge for up to one year, without the need of a trickle charger or battery maintainer, it is an excellent option for those that cannot afford to purchase a solar maintainer at the current time.

So, Do You Need a Solar Battery Maintainer?

While they can be extremely beneficial, especially during long stays in remote locations, they are not exactly necessary. We would recommend avoiding small solar battery maintainers that feature integrated solar panels, as they usually struggle to generate enough electricity to actually keep your batteries charged.

Instead, choose a solar generator that has battery maintainer capabilities. You should treat the purchase as more of a versatile investment that you will use for a wide variety of applications.
