N40(32C24) JIS SMF CAR Battery

BRAVA SMF Batteries feature lead calcium expanded grids (Lead Calcium Technology) for improved resistance to corrosion, overcharging, gassing, water usage, self discharge and thermal runaway, all of which limit battery life in conventional lead acid batteries. The range includes batteries to suit cranking / starting (traditional automotive), high cycle, dual purpose starting / deep cycle and deep cycle applications.

SMF BATTERY FOR CAR

  • Increased battery shelf life – Compared to conventional batteries, up to 12 months shelf life without charging due to the use of calcium / calcium grids.
  • Polypropylene case – Reinforced design is precisely tailored to support the battery elements to withstand road shock and vibration. This strong durable material combines light weight with high impact strength.
  • Heat sealed covers – Helps prevent electrolyte contamination and increase case strength.
  • Low resistance envelope separators – Encapsulated negative plates help to prevent shorting / treeing between negative and positive plates as well as aid vibration durability.
  • Factory-sealed – Makes these batteries maintenance free.
  • Liquid-gas separator area – Returns liquid to reservoir for longer life.

FAQ

1. How to extend the life of a SMF battery?

In order to increase the life of battery, it is necessary to monitor the battery performance constantly. Here are some tips to optimize the battery performance.
1. The SMF battery should be placed in well ventilated area to avoid high temperature environment. With each 10 degree rise in air temperature, the float life reduces to half. If the battery is installed in equipment, it is necessary to isolate it from heat generating components like transformer.
2. In order to prevent deep discharge, it is necessary to set the cut off voltage to 11.5 volts in 12 volt battery and 4.5 in 6 volt battery.
3. It is necessary to prevent no load battery drain. The additional components of the equipment such as sensors, displays and indicators consume power in the no load condition. So if the equipment is not provided with automatic charging, this power loss leads to deep discharge.
4. Boost cum float charging is suitable for SMF battery. If the power failure is frequent, the battery should be charged immediately to acquire full charge before the next power failure.
5. If there is any problem such as low backup time, battery heating, low terminal voltage even after continuous charging develops, the battery should be attended immediately.
6. If the equipment is not using for long time, it should be charged once in every week. If the battery is allowed to charge and discharge frequently, its life can be extended to 3-5 years.

2. What’s the SMF Battery?

Sealed Maintenance Free batteries are widely used where minimal maintenance and space requirements are the main considerations. In UPS systems, it is used because of its maintenance free and eco friendly features. SMF batteries do not require water and acid top up and are totally maintenance free. There is no water loss during the charge- discharge cycle and the battery works on the oxygen recombination principle. SMF battery is also called as Valve Regulated Lead Acid or VRLA battery.
