A 12 volt deep cycle solar battery is a great way to get solar power and store it for later use. They are used in solar panels, RVs, boats, golf carts and other similar applications for standby or daily power needs.

Type, Capacity & Depth of Discharge:

The best deep cycle batteries come in various types, including Flooded Lead Acid (FLA), Gel Cell, Absorbed Glass Mat (AGM) and Lithium-Ion batteries. Each type has its own strengths and weaknesses, so it is important to choose the right one for your particular application.


In order to ensure the best storage capacity for your solar battery bank, make sure you understand the ‘Ah’ rating on each model. Then, pay close attention to the recommended Depth of Discharge, which will affect how long your battery lasts.

The Pros and Cons of Lead-Acid vs Lithium-Ion Deep Cycle Batteries:

If you want to ensure the longevity of your 12 volt deep cycle solar battery, it is important to find one that comes with a warranty. Some come with a warranty that lasts for a year or longer, while others offer up to 10 years.
