1) No needed to distilled water;
TMF battery use special Lead-Alloy for minimal fluid loss meaning that there is no need to replenish distilled water through the life of the battery.
2) Low rates of self-discharge;
Calcium-Silver alloy grids provide prompt turnover even after long periods of standing.
3) Mounted hydrometer(SOC indicator);
A mounted hydrometer allows you to check the status of the battery.
4) Strong charge acceptance;
The use of Calcium-Silver alloy grids and Tubular thin Plate (Ø6.6mm) means that TMF batteries have 20% improved charging ability compared to other batteries, even during intense heat or cold.
5) Long life; Special alloy grids prevent corrosion and extend the life of the battery.
