Buying Guide


After the reviews, we bring a guide for you so you can buy an effective solar deep cycle battery. You want to power up expensive items with the battery so it has to have exclusive features and quality. We collected these guidelines from experts, so you should consider them for your advantage.

Storage Capacity

Deep cycle battery comes with 100Ah up to 200Ah capacity and you can choose the one you need. Remember, that the high-capacity battery is useful if it is leak-proof.

Battery Type

It comes in two categories depending on the technology and material. Like, a lithium-ion battery or lead-acid and AGM battery. With lead-acid, you have to face some installation limitations as described above.

Whereas you are free to install a lithium-ion battery in any position. Those who can’t handle heavy batteries should get a lightweight lithium-ion battery.  At the same time, the SLA battery has its own benefits according to reviews.

Minimum Maintenance

Choose a battery with minimum or zero maintenance, so you can use it for longer. Both types of batteries are maintenance-free as their manufacturers claim.

Multiple Applications

If you have many solar gadgets to power up, better have a multipurpose deep cycle battery. Like, it should be compatible with vehicles, equipment, appliances, other than just solar panels.

Protections

You should also consider the kind of protection available with the battery. A lithium- ion battery prevents the over-discharge, overcharge, short circuit, and over current due to a built-in BMS, Battery Management System. Such protections make batteries safer and more reliable.

Fast Charging

The battery should take less time to recharge which only a few brands offer. So, better look at the specs to see the charging time or get this info from other users. Fast recharging saves time, and it is ideal for outdoor use, like for camper trailers, etc.

Installation Position

It involves certain tools for attachment that depend on its type as well. You can’t install a lead-acid battery upside down. But, the lithium-ion battery is flexible in terms of installation. Most products come with a manual guide with installation instructions so check it before buying.  A professional installer would be a great help in this case, especially, if you get it from the battery provider.

Battery Price

Prices vary depending on the battery features, quality, and type. What you should buy entirely depends on your personal choice and budget. But, a deep cycle battery is not so expensive and most customers can afford it. Sometimes the battery replacement costs you shipping charges, so do consider this factor.

Warranty Time

Some brands offer a one-year warranty whereas some claim that you can use it for 10 years. A genuine source is always more reliable in this case. A battery with a long service life is more economical because you don’t have to replace it often.

Conclusion

The above products are effective and help several users run their solar panels, vehicles, equipment, gadgets, and appliances. You can take benefit from a solar deep cycle battery if you buy it from a good company as poor batteries have discharge issues. Both lead-acid and lithium-ion batteries are effective depending on how you use them.

You should ask experts to find which type of battery is suitable for your panel or device. The main purpose is to store solar power, but if your purpose is just to have a standby power backup tool, both types will work.

The top companies offer a one-year warranty which is quite satisfactory. Most brands offer affordable batteries, besides, they need little or no maintenance that also saves money. On top of all, you save electricity by using solar batteries which is a big advantage.
