Sealed Lead Acid Batteries

We are manufacturing a wide range of VRLA Batteries in mono blocks and in modular designs. Moreover you can avail rechargeable Sealed Lead Acid Batteries and sealed lead acid batteries at very economical prices. SES batteries are carefully designed with precision electrochemistry & pure lead-tin alloy. SES batteries are easy to maintain, have a low self-discharge rate and are less expensive than other rechargeable batteries. Our back breaking efforts and customer support is encouraging us to pursue zero defect product through flawless manufacturing process. We are the heading sealed lead acid batteries manufacturer located in India. In addition, we are one of the genuine sealed lead acid battery suppliers based in India.

CONSTRUCTION

Plates (Electrodes)
Plate construction is the key to producing a good battery. Recognizing this, we utilizes the latest technology and equipment to cast lead tin alloy grids free of antimony. An adequate amount of tin in the grid alloy imparts strength to the plate and guarantees durability even in extensive cycle
service. Lead oxide paste is added to the grid to form the electrically active material. In the charged state, the negative plate paste is pure lead and that of the positive lead dioxide. Both of these are in a porous form to optimize surface area and thereby maximize capacity.

Separators
Separators are made of woven glass fiber cloth with high heat and oxidation resistance. The material further offers superior electrolyte absorption and retaining ability, as well as excellent ion conductivity.

Electrolyte
Immobilized dilute sulphuric acid : H2SO4.

Container
Case material is either ABS, a high-impact proof plastic resin, styrene, or a polypropylenepolyethylene copolymer with resistance to chemicals and flammability.

Terminals
Depending on the model, batteries come either with Faston type terminals made of tin plated brass, post type terminals of the same composition with threaded nut and bolt hardware, or heavy duty flag terminals made of lead alloy. A special epoxy is used as sealing material surrounding the terminals.

Relief Valve
In case of excessive gas pressure build-up inside the battery (usually caused by abnormal charging) the relief valve will open and relieve the pressure. The one-way valve not only ensures that no air gets into the battery where the oxygen would react with the plates causing internal discharge, but also represents an important safety device in the event of excessive overcharge. Vent release pressure is between 4-6 psi; the seal ring material is neoprene rubber.

Case Sealing
Depending on model, the case sealing is tongue and groove with polyurethane, epoxy, or heat seal.

Innovative Features
Long Life In Float And Cyclic Applications
In both float and cyclic applications, SES's sealed lead batteries have proven long life

Impressive Low-temperature Performance
SES batteries offer excellent performance in high and low-temperature environments.

Long Storage Life
Low self-discharge rates mean SES's sealed SMF batteries can be stored for long periods of time compared to conventional batteries.

Dependable Use In Any Application

High Rate Charge/Discharge
Low internal resistance allows a high rate of charge and discharge.

Excellent Mechanical And Vibrational Characteristics
ABS Rectangular Construction & Epoxy Sealing Ensures Inherently Stronger Configuration.

Flexibility Of Design
SES's 2-volt modules allow a wide variety of configurations. the mono-block is conveniently preassemble and features mounting holes for easy mono-block batteries can be charged with either constant current or constant voltage charging.

Chargers for Lead Acid Batteries
Lead Acid batteries have an economical price and a long lifetime. They are a good alternative for mobile power if the very low power density and the resulting high weight have no relevance.

Lead acid batteries can be charged with different charging characteristics. It is important that the maximum charging current is never more than the battery specification. Overcharging of the battery is just as bad as an insufficient charge as both have a serious impact on the lifetime of the battery. Therefore, the charging technology chosen has a major influence on the rechargeable lead acid battery life and durability.

SES has chargers with IV and IVOV characteristics in its lead acid standard charger range.

IV Charging Technology
This technology charges the rechargeable lead acid battery with a limited current. The current decreases slowly during the last charging phase up to the end charge voltage. The charger can be left connected to the battery during charging.

IVOV Charging Technology
During charging with the IVOV technology the battery first will be charged with a regulated charging current (cycle mode) until its voltage reaches a pre-defined value (2.45 V per cell). After the current has decreased to a defined lower value the charging voltage will be reduced to 2.3 V per cell to avoid damaging by gassing (floating mode).

In comparison to the IV technology the charging with the IVOV characteristic achieves a considerably shorter charging time.

While the charger is in operation it can be left connected to the battery. Due to an implemented hysteresis, function of the charging operation restarts when the battery voltage falls below a predefined value.
