Best Batteries for Wind Generator Buying Guide

Wind generator, as well known is unstable but efficient. Well, for you to ensure you get the ideal power supply you need and keep your battery or batteries in check is by buying the ideal one. To do so, you need to consider the factor I have highlighted here before you make your buying decision.

1) Battery Type

The ideal batteries for wind generator charging are the deep cycle batteries. Why? These batteries use chemical reactions inside them to develop voltage, which is then used to power a load. They’re designed for frequent discharge and recharge. It’s precisely what you need for the wind generator.

Unlike those conventional car batteries which provide electrical energy in bursts and in a short time, the deep cycle type provides steady power over a long time.

There are two types of deep cycle batteries which you need now to consider. You can either use an Absorbed Glass Mat battery (AGM) or the GEL Cell. The two are highly resistant to deep discharges, and they are fully sealed. They are also maintenance-free, making them suitable for remote areas and safe to handle.

The AGM battery features a special absorbed glass mat designed to wink electrolyte inside between the battery plates. They also contain enough fluid to keep the rug wet for the electrolyte. That means when broken no liquid spills and require zero maintenance.

The GEL cell batteries, on the other hand, contain silica gel where the battery electrolyte suspends in. It’s a thick paste which allows the electrons to flow through the plates and cannot spill/leak.

Here consider your budget and preference and the rest of the features.

Amp Hour Rate

While buying the best batteries for wind generators, you have to consider the time it will take the battery to need recharging. If you’re looking for long hour power supply or high-end purposes, then I suggest you buy a cell with a high Amp-Hour rating.


The volt capacity will tell you how much power the battery provides. Similar to the amp-hour rate, you do need a battery with enough energy, especially if you will be using it for the high-end applications. For this type of tasks, you will need a higher volt rating. Since wind is unreliable, I advise you to go with the high volt capacity.

Charge Time

Next, know the time it takes to be fully charged. If you need a frequent or continuous use battery, the best battery is with the lowest charging time. That allows you to use the battery faster when it’s down. Check the info on the battery specs before buying.

Size and Weight

It might not be necessary for some consumers, but weight and size is also a factor to consider. That’s if you will be moving it now and then. Movability will depend on the overall weight of the battery. A smaller battery will be much easier to move.

Frequently Asked Questions (FAQs)

What’s the life expectancy of an AGM battery?

The service life expectancy or life span is between 6-15 years depending on usage and exposure to harsh conditions.

Can I use my AGM battery with a solar panel?

Yes, if it’s designed to work with a solar charging system. You have to make sure of that before you connect it.


Each battery in this list is high-capacity, top-performing, and ideal for charging using a wind generator. I have carefully considered every aspect required by a wind generator battery.

So, nothing, and I mean nothing can stop you from buying the best battery for your wind turbine. If still having some problem selecting a model, pick any battery and proceed to purchase. Good Luck!
