Gem Batteries has launched a wide range of tubular batteries to offer its customers with reliable, consistent and low maintenance power for meeting different types of energy requirements. These batteries can be subjected to heavy-duty and are capable of supporting rural and power deficit areas conveniently. Gem has specifically developed its range of tubular batteries keeping in mind the increasing demand in high-tech and smart batteries.

2. Tubular Monobloc Heat Sealed
Polypropylene Batteries
GEM Tubular Batteries are manufactured with Heat Sealed Polypropylene Co Polymer Monobloc casing material.
Tubular positive plates are made of highly corrosion-resistant special lead alloy and Pasted Negative Plates with
high discharge performance to ensure cycling capabilities and also reduce topping-up frequency. Individual cells
are fitted with Micro Porous aqua-trap ceramic vent plugs with sealed float, which prevent acid mist coming out from
the cells to make it convenient for living room ambience.

Tubular Plate Monobloc Heat
Sealed Polypropylene Batteries
GEM Tubular Plate Batteries are specially designed for inverter applications and are made with ultra-thick charged plates for long life & performance. They
are user-friendly batteries with quick initial charging capability, very low internal resistance, and have a steady voltage profile during short & long duration
discharges. The sealed float and ceramic filter plugs help easy maintenance of electrolyte level and ensure no fume emissions. These batteries have a great
charge acceptance and retention properties even in arduous working conditions.
Initial Filling and Charging Instructions
•
•
•
•
•
Fill battery grade sulphuric acid in all the cells up to the required levels
Filling Specific Gravity: 1.220 +- 0.005 at 27°C
Fully Charged Gravity: 1.250 +- 0.005 at 27°C; adjust final working gravity in all the cells
Charge the batteries with constant current as indicated in the table, after 2 hrs. of soaking period, until the top of charge voltage reach 16.20
Volts per battery
Conditions of fully charged:
a) 3 consecutive hourly readings of specific gravity and voltage become constant b) Top of charge voltage will be around 16.2 V – 16.5 V
c) All cells should be gas-free d) Minimum Ah has been given
