How to reduce the cost of battery maintenance?

The most efficient way is to improve battery performance and to reduce the consumption

from float current! Let us take an example for two battery systems of 240V, 700W with

configuration of both conventional and HRL batteries with supposed same capacity:

Conclusion: Annual saving per battery set is 1348 kWh,

37.5% energy saved without any additional maintenance!


Designed for easy installation High rate performance

--- High energy density for compact
