Solar Battery Maintainers

Best Solar Battery Maintainers

Modern humans are getting surrounded by gadgets of all kinds and some of them are now using solar power to get things going (unless you don’t mind polluting the environment further and initiate human extinction). Now, in order to keep them in good shape, we need to make sure that the batteries of these solar-powered devices are taken care of. We need to keep these batteries in good humor and which is why we need to use a battery maintainer.

Solar battery controllers help people maintain the health of the battery by putting a stop to issues like flat discharge or general discharge. These solar battery chargers and controllers do produce some amount of energy and that power trickles into these batteries. These solar trickle chargers don’t charge the batteries in that sense rather what they do is generate a small amount of electricity to make up for the power that gets discharged by the battery automatically. But you need quality solar trickle battery chargers to get things done and which is why we have compiled a list of some of the best solar battery maintainers available in the market. Take a look and choose the ones that suit your needs –

How Do Solar Battery controller Work?

Solar maintainers can convert solar energy into electrical energy but in a small amount and then this energy gets supplied to the battery to make up for the energy that gets lost during the usual discharge process. Solar battery maintainers help to avoid overcharging by cutting off the power supply to the battery and thus help to extend the lifespan of the battery. Solar battery maintainers also help to keep the flat battery alive by passing more power to it. Basically, it is a clever device whose main objective is to extend the lifespan of the battery.

Benefits of Solar Battery Maintainers

There are several benefits of using solar battery maintainers and some of them are listed below –

Different Usages

Solar battery maintainers work with different types of batteries. Be it a lawnmower battery, motorcycle battery, or RV battery, Solar battery maintainers can help them all.

Conserves Energy

Solar battery maintainers help you live off-grid. You don’t have to rely on the grid anymore, as these Solar battery maintainers are powerful enough to keep your battery fully charged even during overcast conditions.

Optimum Battery Performance

As the name suggests, Solar battery maintainers help to keep your battery in good shape as they don’t allow the battery to go flat. They help the batteries to last long and to offer optimal performance under extreme circumstances.

Types of Solar Battery Maintainers

Bracket Mounted Solar Battery Maintainer

As the name suggests, these solar battery maintainers are mounted on a bracket. The bracket adds to its flexibility and adjustability. The bracket allows you to change the direction of the solar panels to get the maximum amount of sunlight possible.

Suction Cups Solar Battery Maintainer

These solar battery maintainers have got suction cups attached to them and this feature allows you to place the solar panels wherever you wish. You can place the solar panels on the windshield, on the boat, or any other convenient spot for that matter. Suction Cups Solar Battery Maintainers are truly versatile.

Power Outputs

When it comes to power output, you will have multiple options to choose from. The higher the power output, the better it is but there is a catch. The higher the power put, the costlier the solar battery maintainer is. Power output between 7.5 watts and 20 watts is more than enough for most of us unless you are using some alien super-technology that consumes a lot of energy. The higher the watts, the faster the battery will get charged.

Solar Battery Maintainer Buying Guide  

1. Charging Capabilities

Most battery maintainers give you the choice of charging directly to the battery with battery leads or directly into the cigarette lighter outlet in your car, truck, or SUV with a cigarette lighter plug. You should also be able to charge even when there is no sun. As long as you have light, even when it is overcast, the solar charger/maintainer should be able to generate power. The UV light from sunlight comes through clouds, so this is all you need. Although you can’t charge at night, you should be able to charge during the day even if it is cloudy.

2. Auto Shutoff

This a crucial feature and the absence of which can lead to a lot of troubles and pains. Most solar battery maintainers that we have reviewed here have got shut-down diodes built into them. Now, you might be wondering what the heck is a shut-down diode. Well, allow me to break it down in simple English. It is basically a kill switch that stops the flow of power into the battery as soon as the battery levels reach full capacity. This is a nifty little feature that eliminates any possibility of causing any damage to the battery or the solar battery maintainer.  

3. Shape

Solar Battery maintainers available in two different shapes – rectangular and square. You need to select the one that fits the space better or you can just select one that has got a better aesthetic appeal.

4. Construction

Solar battery maintainers should be made from premium quality materials otherwise, they will not last long. A good quality solar battery maintainer should have an ABS plastic frame and it should have a high-grade glass panel otherwise, it will not be able to stand the test of time.

5. Mounting

When it comes to mounting, you have several options in hand. You have got a standard stand, suction cup, and a bracket. Choose the one that suits your needs. If you are planning to move the Solar Battery maintainers every now and then, you will be better off with a battery maintainer with suction cups on. However, if you are looking for something semi-permanent, you will do just fine with a Solar Battery maintainer with a bracket

6. Size

Solar Battery maintainers are available in varied sizes. These include the small-sized ones that measure 8 x 10 inches or 20 x 25 centimeters and the large-sized ones that measure 16 x 11 inches or 28 x 41 centimeters. Small Solar battery maintainers are given preference over larger ones as they can be moved around easily and effortlessly.

7. Spark Proof

Ordinary Solar Battery maintainers tend to produce sparks whenever you try to attach them to the batteries. These sparks though harmless can lead to serious explosion or fire and therefore, it makes sense to opt for those Solar Battery maintainers models that don’t generate current unless and until the connection is fully done.
