Factory 12v deep cycle gel battery Energy Power Deep Cycle Lead Acid Battery for solar panel

1.What is a deep cycle lead-acid battery?
A deep cycle battery is a lead acid battery designed to provide sustained power over a long period and run reliably until it is 80% discharged or more, at which point it needs to be recharged.

2.What is the meaning of deep cycle?

A deep cycle battery is a battery that is designed to produce steady power output over an extended period of time, discharging the battery significantly, at which point it must be recharged to complete the cycle.

3.What's a Deep Cycle Battery?
The deep cycle battery is designed to supply steady power over an extended period — like those commonly used in marine vehicles. It’s why this battery is sometimes called a marine battery.

4.How are deep cycle and starter batteries different?

In lead acid batteries, the main difference between a deep cycle and a starter battery is structural. Deep cycle batteries have thicker plates with more dense active material and thicker separators. The thicker battery plates resist corrosion through extended charging cycles.

5.What Are The Types of Deep Cycle Batteries?
The deep cycle function is applied to both lithium and lead acid battery technologies.

>Main Features

 

1. Maintenance free sealed lead acid battery

 

   As it is valve-regulated sealed lead acid battery.sealed and glass mat is used .acid is trapped inside. so refilling is not needed and is

 

  leak proof.

 

2. Low self discharge

 

  The self –discharge rate for FOBERRIA Sealed Lead Acid Battery is about 2-3% per month at room .temperature compared with 20-30%

 

  for other common battery systems.

 

3. Longer service life

 

  Used thick and massive calcium grate ensure that FOBERRIA battery has a longer service life over 10years.

 

4. High discharge rate 

 

  Since the internal resistance is low .the battery can provide high rate of discharge.
