Deep-Cycle Lead-Acid Batteries for Solar
There are two main types of lead-acid batteries available, flooded lead-acid batteries and sealed lead-acid batteries. Both batteries use the same basic chemical principles to produce electricity. Each battery has a positive lead dioxide plate (cathode), a negatively charged lead plate (anode), and a mixture of sulfuric acid and water called an electrolyte.
When the plates are placed in the electrolyte mixture and connected to wires from a solar panel system, they can produce electricity. While both flooded and sealed deep-cycle batteries use lead plates and an electrolyte to produce a current, their designs differ significantly.
Sealed Lead-Acid Batteries
As their name implies, sealed lead-acid (SLA) batteries don’t require topping off the water regularly so they can remain permanently sealed. Instead of replenishing the water supply, SLA batteries have one of two ways to contain their liquid.
The first design is to include separators made from fiberglass between the positive and negative plates. The other strategy is to convert the liquid into a gel. With either method, the batteries will release hydrogen gas during discharges, so you'll still need to keep them in a well-ventilated area, even if storing them on their sides is an option.
Absorbent Glass Mat (AGM) Batteries
When fiberglass is used to absorb the electrolyte and prevent it from leaking or evaporating, it's called an absorbent glass mat (AGM) battery. The fiberglass acts sort of like a sponge and keeps the electrolyte close to the positive and negative plates. This allows AGM batteries to have a deep discharge while still providing the sulfate to mix back together with the hydrogen. This process is what lowers the amount of hydrogen gas released during discharges.
AGM batteries can discharge hundreds of times at up to 80% capacity and usually last around five years when used with a home energy system. While their low maintenance and easier storage make them appealing, they cost up to two times more than their counterparts as the design is more complex and requires more materials.
Gel Batteries
The other type of sealed lead-acid battery is a solar gel battery. AGM and gel batteries come with the same conveniences but operate differently. The silica gel in deep-cycle gel batteries suspends the sulfuric acid, giving the battery greater stability. It also has a lower rate of self-discharge over a long time.
In addition, gel batteries release the least amount of hydrogen gas when they discharge, meaning ventilation isn't as much of a priority. Solar gel batteries also function better at higher temperatures than their competitors, making them wise for warmer climates. However, the gel can run into issues in colder climates, something to keep in mind if you plan on storing your batteries in a basement or garage during wintertime.
Because deep-cycle gel batteries can easily overcharge, you need to observe them rather closely to ensure a longer lifespan. It’s essential you connect these devices to the appropriate battery charger. A deep-cycle gel battery charger can monitor voltage and prevent it from going over the limit that solar gel batteries can handle. Without the proper gel cell battery charger, you may end up disappointed in your gel batteries' performance.
