Unlike the traditional wet batteries agm batteries only hold a small amount of acid which is entirely absorbed by the glass mat.
Gel cell deep cycle battery vs lead acid battery.
While the benefits of a gel battery are pretty hefty so is the price tag.
The gel cell battery excels in slow discharge rates.
They are deep cycle batteries which means that they can discharge more and still be recharged like new.
This article will focus on the differences between the main lead acid battery types used in the solar industry.
There are some agm batteries we sell that offer excellent 80 deep cycle abilities.
Notice the differences in bulk absorb and float charging agm flooded and gel deep cycle batteries.
Agm stands for absorbed glass mat which is a unique mat designed to trap the electrolyte between the plates inside the battery agm batteries are also known as sla batteries or vrla batteries.
When attempting to charge a gel battery with a lead acid charger you must ensure the peak charging voltage does not exceed 14 7 volts which would result in dried non conductive gel.

Today a gel battery will cost roughly 30 more than that of a wet lead acid battery with none of the headaches maintenance or charging issues.
Step 1 attach the lead acid battery charger to your gel cell battery connecting the red cable to the positive terminal and the black cable to the negative terminal.
Many people looking to switch from wet cell to gel batteries see this as the biggest drawback.
Flooded lead acid is still in use today particularly as an automotive starter battery and as a low cost deep cycle unit in the leisure industry.
As a result gel batteries are now more commonly used in floor scrubbers and floor sweepers.
For a 12v system they do not like 15 5 v.
Gel batteries are best used in very deep cycle.
The cons the price.
The electrolyte in a gel cell battery has a silica additive that causes it to set up or stiffen.
As higher volumes were produced for the gel batteries they rapidly reduced in price and increased in quality.
Every battery type has a different purpose and use case so let s go over the pros and cons of each.

Gel cell batteries are typically a bit more costly and do not offer the same power capacity as do the same physical size agm battery.
Sla stands for sealed lead acid vrla stands for valve regulated lead acid.
Gel cell batteries aren t that way.
As a rule do not equalize agm or gel batteries.
Please set your charger to the type of chemistry your battery is.
Skip to main content.
You ve got flooded lead acid and sealed lead acid batteries and the latter group can be broken down into agm absorbent glass mat and gel batteries.
Agm also became known as a type of sealed lead acid sla battery.
Agm had given greater flexibility to lead acid but it hadn t perfected all the flaws.
This is probably the most sensitive cell in terms of adverse reactions to over voltage charging.
