	Deep Cycle Batteries of Flooded Designs
	Luminous Flooded Deep cycle batteries come in two variants

	Batteries which are required to discharge for considerable period of time and deliver a large part of t heir rated capacity in each of these discharges are prone to higher rate of corrosion of grids and shedding of active materials from plates. Hence normal flat plate batteries used in SLI applications are not suitable.

	Luminous Deep Cycle Flat Plate batteries have thick and heavy grid design with special alloys, which retard this oxidation/ corrosion and give them a longer life in deep cycle applications. The plate active material pasting and also the paste's mix along with special curing process hold the active material against shedding.

	The Luminous Tubular batteries even have a more robust design. The grids are replaced with heavy spines of special alloy, which do not corrode even after 7 to 10 years of operation. The active material is held inside polyester fiber tubes, which totally stop shedding under heavy and deep discharge conditions.

	Application
	These batteries are best suitable for high ambient temperature and partial state of charge usage, they are used in various applications like domestic inverters, off grid solar photo voltaic system, home lighting systems, alarm systems, signaling equipments and remote telecom units.

	The Key Advantages:
	Medium to very long service life - ranging from 2.5 - 4 years for Deep Cycle design and up to 7 - 10 years for ultra Deep Cycle Tubular design. Depending on depth of discharge, frequency of cycling and battery temperatures.

	Compact size with high specific energy. Accomplished by special design of plates containers and separators.

	Very low water topping up frequency. Special alloy plates cause LOW or NO water loss from battery.

	Better Design: Better Performance
	Thick flat pasted plates with selenium grids and automated vapour; curing process generates suitable proportion of binding crystals in the plates

	The Result
	Much longer cycle life that most of the flat plate batteries in the world. A cycle life of over 500 - 600 cycles under deep discharge conditions is delivered.

The tubular plate batteries are designed extremely strong and can withstand 1400 cycles of deep

discharge at 80% discharge levels in its life time

All the plate grids in flat plates and the spines in the Tubular plates are cast in automated high-pressure

machine with maximum 2.5% antimony alloy. Every plate and every cell element is carefully weighed

to achieve uniformity within a close tolerance level. Very low internal resistance is achieved by using

extra large inter cell connection which are tested 100% in the assembly line and also by high porosity

PE (Poly-Ethylene) separators. Tough and high tensile poly - ethylene pocket separators are used in

place of cheap PVC separators that are used by many others. This adds to reliability under abusive

conditions and stops failure from short circuits.

Key Advantages:

Up to 10 year of service life

Very-very low water loss

Very-very low self-discharge loss. Due to this, the battery can be stored in charged condition, for

very long time without getting discharged.

All batteries of same type will have very uniform internal resistance. Large numbers can be

connected in series or parallel without any danger of misbalance within the battery bank.

Very low internal resistance gives you high voltage on discharge and extra back up on load.

You get longer back up in a Luminous Digital Power Battery as compared with any other

battery of same capacity, much better value for money.

Ceramic vent plugs arrest evaporation loss of water.

The tubular batteries are used in the following applications: UPS systems where power

demand is for longer period, Inverters under same conditions, Solar PV systems, Telecom

applications - both Base stations and at Repeater stations, Backup systems in Power stations

and Sub stations and Switch yards, Railways signaling use, etc
