As the name suggests these batteries are called as Valve Regulated Lead Acid Batteries. These batteries are predominately used for UPS applications both in stand by use and cyclic use.

Rocket's Superior Gas recombination technology ensures that more than 90% of the electrolyte is reused resulting into very low water loss and confirms its maintenance free operation. (dimensions & wattage chart)

After receiving a charged battery connect it to the ups(load) system at the earliest.if the battery is kept in idle condition for more than one month , give a full charge and then only connect to the ups/inverter(load) system.
For best results the battery is to be operated at below 40°c.continued operation at high temperature will shorten battery life.
Over charging of battery is indicated by the high excessive temperatures and frequent topping up suitably adjust the charger voltage settings.
Under charging of battery is shown by the progressive decrease of specific gravity suitably adjust the charger voltage settings.
Topping up of cells should be done once in 4 months. Add d.m. Water to bring up to the float mark level at regular intervals to avoid exposure of plates.
If the battery expected to operate continuously in cold climate,(i.e., average ambient temp. Through out the year is less than 15 °c) the sp.gr. Of initial filling battery grade acid used shall be 1.280+/- 0.005 at 27 deg.c

.

2v cells designed to suit the system configuration requirement.
Low antimonial alloy grids for achieving low topping up frequency of minimum once a year.
Provided with transparent sealed level indicators to indicate the topping up requirement
Provided with micro porous ceramic vent plugs to minimize topping up frequency.

.

Specially mixed corrosion resistant alloy for spines & grids
Tubular gauntlets of high brushing strength with high performance for positive plates
Specially made cross ribbed P.E. Separator Envelopes
Electrolyte volume per AH is very much higher than ordinary Tubular batteries.
Almost maintenance free battery
Tower type design requires less floor space
Specially designed vent plugs to trap water loss
