Tubular batteries use positive tubular plates with low antimony alloy to reduce frequency of topping-up intervals. Negative plates are of pasted grid type with lead calcium alloy.
Their separators are made of high quality micro porous material. Micro Porous aqua-trap Ceramic Vent Plugs for individual cell-prevent acid mist coming out from the cells making it convenient for living room ambience.
Main Applications
- Solar powered systems
- Uninterrupted power supplies
- Telecommunication system
- Communication networks
- Emergency lighting systems
- Fire & Security Equipment
- Process control systems
