Battery Security Force SF 1240 Review

It works fine, there were no long shutdowns, therefore, it coped perfectly with a shutdown for 1 hour, a discharge of 10%, a Proterm KLOM boiler with a semi-turbo extension is connected, a KN boiler

It is very difficult to write reviews about rechargeable batteries, since they fully show all their advantages and disadvantages only during long-term operation in various operating modes.
