Universal tubular batteries are robust and proven tubular plate technology batteries, ideal for use in all standby, deep cycling and shallow cycling applications that require high levels of reliability. They are designed and manufactured according to relevant standards.

Tubular Batteries are assembled with tubular positive and pasted negative plates made of a special alloy. They are provided with transparent sealed float indicators and Micro Porous Aqua Trap vent plugs, which allow generated gases to escape and traps water particles, returning the major portion to the electrolyte. This reduces the frequency of topping up. With extra electrolyte head and proper voltage control, the frequency of topping up will be once a year. For the available series of Tubular Batteries please refer the types.

• Unieco Series of tubular batteries are rated at C20 capacity
