4V, 400mA Battery (Rechargeable Battery)

4 Volt batteries are maintenance free and Spill proof because of this 4 Volt rechargeable battery can mount on any position trouble-free safe operation. 4 Volt batteries are mostly used in led torches, emergency lighting battery, battery backup units, security equipments, fire and burglar alarms battery and flashlights in Sri Lanka. Most sealed 4 Volt batteries generate gases during charging these gases are recombined in oxygen cycle to avoid the process of adding electrolyte. Under normal operating conditions 4 Volt batteries are durable & shock resists. Sealed 4 Volt batteries now a days comes with Low self-discharge rate, this allows a fully charged battery to last for longer periods of time before charging is required. The usual discharge rate is 3.3% per month. Most battery’s are effected by exposure to heat, by storing the battery at lower temperatures will further extend shelf life. Normally a 4 Volt rechargeable sealed lead acid battery can be discharged between -40°C to +60°C (-40°F to +140°F). Charging temperatures ranging from -20°C to +50°C (4°F to +122°F). 4 Volt batteries are utilized in a wide variety of applications including, Consumer Electronics, Electric Vehicles, Engine Starters, Golf Carts, Hunting, Lawn and Garden Tools, Medical Mobility, Motorcycles, Power sports, Portable Tools, Solar, Toys and Hobby, Access Control Devices, Emergency Lighting, Security and more. To charge the battery you don’t need an external charger if you have a device. If you don’t have a device and charging with a battery charger first Attach the battery cable clamps, the red wire goes in to the “+” terminal of the battery and the black wire goes in to the “-“ terminal of the battery. Charging at a higher rate can damage your battery and may be dangerous. Lead-acid battery chargers continue to charge until you turn them off. Made with absorbent Glass Mat (AGM) technology for Low discharge rates performance.4 Volt battery is commonly used for emergency spotlights and flashlights. General 4 Ah batteries can be used as replacement battery for most electronics.
