Gem Tall Tubular Batteries
The Legendary GEM Tubular reliability now comes maintenance free from the state of the art manufacturing line. GEM launches new Powersafe XHD series with unique GEL technology mainly for UPS application. These batteries are designed with tubular positive plate and GEL Electrolyte.
Tubular Positive plates, well established for partial state of charge operation make Powersafe XHD series a durable battery for deep cycling application even in heavy power cut areas. The GEL electrolyte makes it compact and maintenance free with no topping up for life. Powersafe XHD is a VRLA backed by Tubular strength
GEM Tubular Plate 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
-
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
