Servotech SERVBAK STB-400+ (40Ah/12VDC) Tubular Solar Battery for Home 60 Months Warranty Flooded Solar Battery  (12 V)

The positive plate support in Ceil Tubular Batteries is cast at high pressure (100 Bar) on an imported HADI machine, ensuring void-free structure and consistent grain orientation, aswell as protecting the plate support from anodic corrosion. As a result, improved reliability and longer life are assured. Ceil Tubular plates have a low antimony concentration, which minimises the frequency of filling up and makes the battery low maintenance. This also keeps the float charging current low, lowering the overall energy required to keep the battery charged during standby float.
