SOLAR AND BACKUP BATTERIES FOR AUTOMATIC GATES
Cheating on the maths when working with solar will bring
your installation unstuck every time and selection of the wrong battery
will also bring frustration and tears. Car and truck batteries as well
as deep cycle batteries will simply have short lives. It has taken us
years of testing to arrive at this range and we suggest choosing
the correct model every time.
The batteries below are all 12 volt. Use two batteries in series for 24 volt systems. Batteries are rated by "amp hours" which simply means the larger the amp hours - the bigger the tank and therefore the longer the tank lasts without filling.

Solar install - Choosing between Sealed Lead Acid (SLA) and Lithium.
The question is it really worth the extra you pay for a Lithium battery. The first thing to understand that both SLA and Lithium batteries like most things in life are not all made the same and will not all perform the same. However if you look at a good quality SLA battery and a good quality Lithium battery you should expect the Lithium to be at least double the price of the SLA of the same capacity. So is it worth the extra?
A lot depends on your site and installation. There is a big difference between an installation in Outback Queensland and regional Tasmania. One site may be bathed in sunshine almost year round and the other may experience long periods without adequate sunlight. The Lithium battery might well be a very good choice for the Tasmanian site.
A SLA battery has a shorter life cycle to start with than a Lithium battery. The SLA also dislikes dropping to anywhere near half capacity and struggles to refresh shortening the life cycle. The Lithium battery can maintain full voltage until almost empty and happily recover back to full capacity many times over.
Short answer is Lithium is more resilient and will last longer. A good investment for difficult sites.
