The Top 5 Solar Batteries For Home Energy Storage

There is no point having solar panels in your home if you don’t have the best batteries to store power for use when the sun goes down is there?

A solar battery needs to have the durability and strength to provide the power that you need for a long period of time. If your solar battery lets you down then you will be in trouble so you need solar batteries that you can depend upon.

We decided that we would help you by testing a number of solar batteries and then create our top 5 list so that you can be sure of purchasing the right one. We review all five batteries here for your convenience.

The solar batteries that appear here deserve to be as they were the best from our tests in terms of price and performance. We have provided you with the important information that you need to make the right choice.

Best Solar Battery

There were a number of solar batteries tested and we have really chosen the best five for you here.

We rejected a lot on performance and some because of their high price (you do not always get what you pay for).

So here are the five that made it to our best solar battery list:

Vmaxtanks Vmaxslr125 AGM Deep Cycle 12v 125ah SLA rechargeable Battery review

When you are looking for a solar battery you need to consider one that is safe to use in your home. The Vmaxslr125 is a very good choice for this. This is a high performance solar battery with a very long life span. It uses deep cycle technology which is just right for solar battery storage.Vmaxtanks Vmaxslr125 AGM

The Vmaxslr125m has an expected lifespan of 8-10 years. This lifespan assumes that the battery will be used constantly, being charged and maintained just as it should be. If the battery is left dormant and inactive for a long period of time then the overall lifespan is likely to be reduced.

The Vmaxslr125 is a very well made and durable solar battery. Primarily for indoor use, this battery can be used external as its design will withstand even the most extreme of weather conditions.

You can literally use the Vmaxslr125 in any position thanks to the techniques used for sealing in its construction. It is guaranteed to be leak proof and the battery is non hazardous which is why it has been approved for maritime, surface and air transport of the military.

This battery has an AGM (Absorbed Glass Matt) electrolyte suspension system. What this does is assist in the total absorption as well as the containment of the electrolyte. This battery does not contain any silica gel.

You will not be required to add any water to the Vmaxslr125 for the checking of the specific gravity throughout the float service life. The self discharge rate is low at around 1-2% of the rated capacity each month. This is measured at room temperature.

The performance of the Vmaxslr125 is very impressive. The design of the battery ensures an ultra low resistant which means that it is 99% efficient. It has a high power density due to the technology used in assembly.

The Vmaxslr125 weighs 75 pounds and has dimensions of 12.9 inches long by 8.7 inches in height and 6.8 inches wide. It is pretty much a solar battery beast. It is heavier than a lot of the other batteries available but once it is in place this is not a problem.

This is a high quality, high performance and long lasting battery that is well worth the money and our top recommendation.

Pros of the Vmaxslr125

These are summaries from real customer reviews:

  • “Very good performance” – there were a number of positive comments about how well the Vmaxslr125 performed even when placed under considerable loads.
  • “This battery is high quality” – a lot of customers thought that the quality of the Vmaxslr125 was excellent. People purchased more than one of these batteries for their applications because they were so impressed.
  • “Completely safe for indoor use” – the customers that used this battery for indoor use were very complimentary about how safe it was.

Cons of the Vmaxslr125

These are summaries from real customer reviews:

  • “The battery was defective” – one customer reported that the battery didn’t work at all after receiving it. This was an isolated incident and the customer has full warranty coverage.
  • “Didn’t hold a charge after a while” – this again was the experience of one customer. Nobody else experienced this problem so not considered to be a big issue.
  • “Battery is very heavy” – this is an interesting comment. This is a well constructed and has a very long lifespan. Of course it is heavy!

Vmaxtanks VMAX SLR155 AGM 12v 155ah review

If you are looking for even more power from a high quality, long life solar battery, then look no further than the VMAX SLR155.Vmaxtanks VMAX SLR155

These batteries can be used on 12 volt, 24 volt or 48 volt systems.

Like most VMAX batteries the plates are military grade custom and these high quality plates will deliver an incredibly high lifespan of 10 – 12 years when used in float mode. As with all solar batteries if there are prolonged periods of inactivity or the battery is used incorrectly then the lifespan will be reduced.

These batteries are idea for solar panel storage but they can also be used with wind turbines and other inverters. The maximum charging current that the VMAX SLR155 can handle is 35 amps and the charging voltage is recommended at 14.7 volts.

Before you buy this battery you can use a battery calculator to assess how many batteries you need for your specific application. This will take into account both AC and DC requirements. The VMAX SLR155 weighs over 90 pounds and it is 13.5 inches long, 11.3 inches high and 6.8 inches wide.

You can use the VMAX SLR155 safely both indoors and outdoors and because of its totally leak proof design you can store these batteries at any angle. The battery is completely maintenance free and you will never have to deal with gases or dangerous fumes. It uses non hazardous materials as well.

The VMAX SLR155 has a fast recharge rate and like other VMAX batteries uses an AGM (Absorbed Glass Matt) electrolyte suspension system. This improves the efficiency of the battery overall.

This is the perfect solar battery where high power output is required. It is more expensive than some of the others in our list but you certainly get a lot of battery for your money.

Pros of the VMAX SLR155

These are summaries from real customer reviews:

  • “No other solar battery comes close” – there were many customer comments about how well the VMAX SLR155 performed and many stated that it was an “exceptional” product which met all of their requirements.
  • “The quality is amazing” – several customer reviews commented on the high quality build of the VMAX SLR155.
  • “Very high power from this battery” – the power output of this battery was something that almost all of the customers were happy about. There were examples provided of how a single battery was powering several appliances with ease.

Cons of the VMAX SLR155

These are summaries from real customer reviews:

  • “Didn’t work well for some golf cart applications” – one customer was disappointed with the VMAX SLR155 when used on a specific golf cart system. Although this battery can be used in certain golf carts it is primarily a solar battery so this was not considered to be a big problem.
  • “Only worked for two months” – another customer found that the battery stopped working after only two months. You should expect that the odd battery in a batch will be defective which is why there is a full 12 month warranty.
  • “It is very heavy” – yes it is! This is a solidly built battery designed to last a long time.

NPP 12V 150 Amp NPG12 150Ah Rechargeable Gel Deep Cycle Battery review

The NPG12 150Ah is different to the first two batteries that we have reviewed as it is a gel battery rather than using lead / acid technology. Many people believe that gel technology is better than lead / acid as it holds charge better and should last longer.NPP 12V 150 Amp NPG12 150Ah

This battery has a high quality construction and the case is made of an ABS plastic which is strong and non conductive.

Summary

We hope that you found all of the information that you need in our top 5 solar battery review.

We strongly believe that the 5 solar batteries that made it to our list are the best in terms of performance and price.

If you want quality and performance then the Vmaxtanks Vmaxslr125 AGM Deep Cycle 12v 125ah take some beating.

If a gel solar battery is a preference for you then go for the NPP 12V 150 Amp NPG12 150Ah Rechargeable Gel Deep Cycle solar battery.
