Tubular Batteries

Gem Tubular Batteries are manufactured with Heat Sealed Polypropylene Co Polymer Monoblaccasing 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.

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.

• 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:
  • 3 consecutive hourly readings of specific gravity and voltage become constant
  • Top of charge voltage will be around 16.2 V – 16.5 V
  • All cells should be gas-free d) Minimum Ah has been given

• Extremely high purity, corrosion-resistant proprietary Spine alloy ensures longer life.

• Extremely superfine void-free grain structure ensures corrosion resistance and high operational life.

• World-class spine manufacturing process using state-of-the-art ZIBO pressure die-casting machines.

• Extra-strong, flexible oxidation-resistant gauntlet for higher performance and extremely long cycle life.

• Highly puncture-resistant DARAMIC-USA separator minimizes the possibility of internal short circuits.

• Equally spread positive active material for better functioning and very low top-up

• Extra-strong, flexible, oxidation-resistant Gauntlet

• Highly puncture-resistant DARAMIC-USA separator to prevent short-circuits Better and quick charge acceptance

• Design-cycle life of over 1250 cycles at 80% Depth of Discharge (DOD)*
