I’m not going to beat around the bush and waste your time if you are looking for high quality but affordable 100ah deep cycle battery than this article is exactly what you are looking for.

There are hundreds if not thousands of different 12v batteries to choose from available on the market right now and choosing the right one can be a challenge.

I’ve tried 4 different 12v 100ah batteries made by different companies and all were garbage that is why you need to be very careful when shopping for a 12v 100ah battery.

So Which 100ah Deep Cycle Battery Do I Recommend?

Well, the only battery that I highly recommend is the Mighty Max Battery for Solar Wind DEEP Cycle.

You are going to be amazed by the reviews since a lot of people are also highly recommending it which means it really does the job even though it quite cheap.

How long can it really last?

Well, that depends…

Some people use it to power their RV’s, some people use it when going for long camping trips and some use it just to power their refrigerators when there is an electricity shortage such as load shedding so it really depends on what you are using it for. 

Can you mix this battery with a non-deep cycle battery?

No, don’t… batteries do not mix.

I wouldn’t mix this battery with a non-deep cycle. It will be a disaster because it is recommended to only pair batteries with the same chemistry.

Caution: Please do not ever use the 100AH battery in the place of a 113AH battery because you are going to be very disappointed… 

Don’t ever mix chemistries. If the original one is a lead-acid, please don’t replace it with a NiCad or Lithium battery because you are going to be very disappointed.

There is no such thing as a perfect deep cycle battery, this battery is also not perfect but it affordable and it worked way better than I expected. 

What kind of hardware do you need to connect to the post of the 12V 100AH Battery?

The controller should shut down automatically when the battery is fully charged so there is really nothing to worry about.

Also, you can see this video for a better understanding of the charging process.

What is the Depth of discharge?

Well, I’ve heard that you should never go deeper than 60% because that will decrease the life span of your battery.

If you want your battery to last you for a few years to come then don’t go deeper than the recommended 60%.

How long can this last?

To be honest, I’m not sure because I just bought it two months ago, but the battery is well made even though I haven’t used it long enough to speak on its longevity.

It is really worth the money?

I personally believe so even though I’ve only have been using it for only two months.

 I’ve recommended this battery to about two of my best friends and they both told me that they loved it… if it works for me and both my friends than it should also work for you too.
