What Is A Gel Cell Deep Cycle Battery

Continuous overcharging or undercharging is the worst thing for an sla battery.

What is a gel cell deep cycle battery.

A deep cycle battery is a battery designed to be regularly deeply discharged using most of its capacity. They are deep cycle batteries which means that they can discharge more and still be recharged like new. Check the battery terminals for corrosion and or battery deformation. A gel battery design is typically a modification of the standard lead acid automotive or marine battery.

Many gel batteries also use one way valves in place of open vents which help the normal internal gasses to recombine back into water in the battery. Gel cell batteries aren t that way. Many people looking to switch from wet cell to gel batteries see this as the biggest drawback. Of course a higher cycle life doesn t come for free.

For example discharging a gel battery at 30 gives you about 2 600 cycles compared with only 1 200 cycles with agm batteries. 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. While the benefits of a gel battery are pretty hefty so is the price tag. Disconnect the charger after the battery has been fully charged.

The cons the price. Battery chargers with gel profile will have information either on the unit or in the manual about gel compatibility. Storing in a discharged state will kill the battery. In fact if you discharge a gel battery to 90 it will give 700 cycles which is more cycles than an agm battery discharged at only 50.

The battery is well suited to different uses ranging from boats scooter and even wheelchairs. And contrasted with starter or cranking automotive batteries designed to deliver only a small part of their capacity in a short high current burst for cranking the engine. Gel batteries are best used in very deep cycle application and may last a bit longer in hot weather applications. A deformed battery or corrosion on the terminals is subject to failure.

This article will focus on the differences between the main lead acid battery types used in the solar industry. If the incorrect battery charger is used on a gel cell battery poor performance and premature failure is certain. The term is traditionally mainly used for lead acid batteries in the same form factor as automotive batteries. Every battery type has a different purpose and use case so let s go over the pros and cons of each.

The universal ub121000 45978 agm battery is a high end deep cycle battery with crank ratings of up 13 8v. The battery also has a power of 100ah which is very impressive and ensures that the battery lasts for a long period. Since gel batteries never spill they are sometimes referred to as non spillable batteries dry cell batteries or maintenance free gel batteries.
