Mg Jacobs 6V 4.5Ah 20H Sealed Lead-Acid Battery

Jacobs valve regulated sealed lead acid batteries are maintenance free, easy to handle, rugged and economical. They have the amazing characteristic of high discharge rate, wide operating temperature, long service life and deep discharge recovery.

Maintenance-Free Operation

 technology ensures efficient gas recombination up to 99% and freedom from electrolyte maintenance. During the expected float service life of Jacobs batteries, there is no need to check the specific gravity of the electrolyte or add water. 

Good Discharging Ability

Tight assembly technology ensures an excellent high-rate discharge performance. 

Long Service Life

A unique corrosion-resistant grid alloy ensures that the batteries have long service life. 

Low Self Discharge

Using high purity raw materials ensures that Jacobs batteries have less self-discharge.

Environmental & Non-polluting

Gas Recombination technology ensures the battery high seal reacting rate, which can prevent the acid fog from separating out. 

Safe & Reliable

Efficient venting system automatically release excess gas when the pressure rises above the normal level & reseals the valves when it returns to the normal rate, which can protect the battery from bursting.
