Valve Regulated (Sealed) Construction.
The battery is of the Gel ( gelled electrolyte technology), valve regulated (sealed) VRLA rechargeable type. The acid is immobilised in a specially formulated mixture of gelling agent and sulphuric acid electrolyte. All the acid is absorbed in this manner and it provides a safe non-spillable Battery.
Gas Recombination System.
The gasses generated in the normal charge/discharge use of a rechargeable battery are internally recombined during normal operating parameters. In fact, in normal operational use, more than 99% of the gases generated are recombined.
Maintenance
The battery has been designed and built such that no addition of electrolyte is needed during the life of the battery. There is no requirement to add water or take time consuming specific gravity readings.
Battery Life - Float Service
The SEC TLG battery is suitable for float (standby) service with life of 10 years at 20 oC
Battery Life - Cycle Service.
The battery is designed for 400 to 2800 charge/discharge cycles, actual quantity
will depend on the depth of discharge. (see cycling curve)
Safety Valve
If excess pressure builds up within the battery, the safety valve automatically opens releasing the gas at 1-3 p.s.i then automatically closes. Fitted with optional Mini-Catalyst to enhance the gas recombination, reduce cell dry-out, lower float current, minimize thermal runaway, positive plate corrosion and negative plate polarization. The valve does not allow the ingress of oxygen which is harmful to the efficient operation and life of the battery.
Temperature Range for Normal Operation
The battery has a wide operating temperature range. However for maximum life and safety, continuous operation over 45 Deg C is not recommended for any VRLA battery.
Grid Design and Paste Formulation.
Our partner battery company has optimized the grid design and paste formulation to maximize the operating and storage life of the battery. This optimized design provides the following advantages:- Excellent recovery from deep discharge or over discharge. Low self discharge to ensure maximum storage time when not in use. Excellent cycling capability. Adequate safety margins in tough operating conditions.
Use In any Position.
The TLG battery is designed to use in horizontal and vertical positions. These features make the batteries suitable for renewable energy deep cycle applications.
Battery Types *12TLG 60, *12TLG 90 and *12TLG 110 have a central manifold gassing systems,which incorporates a sintered PP flame-arrestor membrane so that they can be used in enclosed cabinets, and any gases vented and dispersed safely to the outside environment.
With the V-0 cover and case material batteries available to meet BS 6290 Part 4.
Constant Voltage Charging.
It is recommended to use Constant Voltage method of charging for Valve Regulated lead acid (VRLA)
batteries. Charging voltages must be regularly checked and to optimize the battery performance it is necessary to ensure that the voltage is kept within the following limits.
Float Service 2.25 ??1% Volts Per Cell at 20/25 Deg C.
Cycle Service 2.35 ??1%Volts Per Cell at 20/25 Deg C.
Temperature Effects
Temperature affects the battery in a number of different ways. The battery will operate in extreme temperature ranges from below Zero to over 40 Deg C. However the Valve Regulated (VRLA) Battery nominal capacity, and optimum performance are based on operating temperature of 20 Deg C. Above this temperature the Battery capacity will increase slightly, however the life will decrease at the higher temperature. When designing your battery system the different discharge and recharge performance at different temperature should be taken into account. Please contact us for prices and size. AH range from 10AH-280AH : Volt Range from 6Volts-12volts Electric Scooter replacement battery packs are available at very competitive prices.
