SMF BATTERIES (SEALED MAINTENANCE FREE BATTERIES) – GEL TYPE

Maintenance Free & High Performance
"SAKTHI" maintenance - free rechargeable battery incorporates most recent advances made in the lead acid storage battery technology. Combining the excellent qualities of traditional lead-acid batteries and dry cells, the battery has been specially designed to provide superior performance and longer life with high efficiency. It can be used in series or parallel to give a wide choice of voltage and capacity.

FEATURES

"SAKTHI" Battery is rugged in construction. With the containers made of high impact polystyrene / ABS depending upon its capacity. The battery offers superior resistance to heat, shock and vibration.

The positive and negative grids made of special lead alloy, lead to long and maintenance free operation.
The gel type electrolyte supported with fiber-glass separators ensures leak-proof operation.
The specially designed venting system permits the maintenance of optimum internal pressure in the battery.
The completely sealed battery with dual cover construction provides leak-proof and spill-proof performance.
The output terminals are either tag type, screw type or pillar type depending upon the capacity of the battery.



HIGHLIGHTS

Maintenance - Free
There is no need to add distilled water during its service life.
Long Cyclic Life
The cycle life of the battery is excellent.
Cycle Use
100% dept of discharge-approx. 160 cycle
50% depth of discharge-approx. 300 cycle
30% depth of discharge-approx. 700 cycle
Stand by use
Two years
The battery is designed for both cyclic / boost and float application and high or low rate of discharge.
Low Self-discharge The internal losses are so low that a charged battery can be stored up to 2 months without frequent charge.

Mounting Position It not only provides flexibility in mounting position but also operates reliably in any position.
Convenient Because there is no gassing, the battery can be placed inside the control panel. It is easy to handle, safe and pollution-free. The battery which is free from corrosion of the terminals does not require a separate battery room.
Ready-to-use The battery is supplied in fully charged condition and can be put to use immediately.
Economical The battery gives high power per unit of weight and volume.
