TUBULAR BATTERIES: Extra power High Reliability
"SAKTHI" stationary Tubular Battery has been designed and developed for applications requiring high reliability related to diverse conditions of charge and discharge cycles.

The tubular positive plates and the pasted negative plates ensure extended life over float / trickle charge. Capable of withstanding deep discharges. "SAKTHI" battery requires minimum maintenance adequately provided by special vent plug either with ceramic or aqua trap recombination types available on option.

The battery can be kept on float cyclic or boost / trickle charges.

Since our Batteries are used for Solar application, all the care has been taken to improve the quality of our “Tubular Batteries”, by using special Antimony-Selenium alloyed Lead, virgin Oxide, High quality Polyester Tubular Bags (PT Bags) and excellent processing techniques. We have used special purpose Ceramic Vent Plug / Float vent plug to improve topping interval.

FEATURES

Containers
Hard rubber cell jars / Monobloc containers conforming to IS 1146-1981 resist tough beating normally encountered in service life
Tubular Positive Plates
High oxidation and acid resistant gauntlets, specially designed to envelope spines of the positive grids and hold the active material in position without hampering the free movement of acid, guarantee high performance at all loads.
Negative Plates
The pasted type negative plates are of sturdy construction. The active material is a blend of oxide, special additives and expanders which helps the battery to perform better and ensures its longer life. As a result, a high ampere-hour efficiency of more than 90% and a watt-hour efficiency of over 80% are achieved
Grid
The special grid alloy resists anodic corrosion, reduces water loss and ensures long service life of the battery with low maintenance.
Separators
The micro porous separators are made of high quality sintered PVC conforming to IS 6071-1986.
Vent Plug
The flame retardant ceramic vent plugs prevent the evaporation of water from the cell. The porous structure traps escaping acid vapor but allows the gases to go out.
Electrolyte
The battery should be filled with pure battery grade sulphuric acid with specific gravity of 1.220 +/- 0.005 at 270C confirming to IS: 266. When fully charged, the specific gravity should rise to 1.250 +/- 0.005 at 270C. Care should be taken to maintain the same specific gravity during the service life of the battery



MAINTENANCE

Keep the battery cover and terminals clean & dry. Apply petroleum jelly on the terminals to avoid corrosion. The surrounding area should also be kept clean & dry.
All electrical connections should be tight to avoid heating up and prevent short circuit.
Care should be taken not to short circuit the cells while using tools such as spanner.
After use, charge the battery promptly. If the battery is left in a discharged state, the plates would tend to sulphate.
During charging, do not allow the temperature of the electrolyte to rise above 540 C. Interrupt the charging to cool the electrolyte.
As a safety measure, ensure good ventilation in the battery room to remove the explosive hydrogen gas. Do not bring open flame or lighted cigarette, etc near the battery as otherwise; it could lead to an explosion.
When many batteries are connected in series or parallel, after a few months, equalization charge may be required to rectify any in-equality among the cells that may develop during service life.
