Electric fencers zinc air-saline batteries are SUITABLE FOR low and medium consumption energisers.
The usage period is in the range of 1 to 7 months.
You can connect the battery, then disconnect it and connect again after few months (because of low self-discharging).
ZINC AIR BATTERIES use atmospheric oxygen to produce electrochemical energy. Since one active material lies outside of the cell, the majority of the cell‘s volume contains the other actice component (zinc), so zinc air batteries have very high energy density. Using a reactant from the air saves on space, reducing the size and weight of the battery.
ZINC AIR-ALKALINE BATTERY
Higher discharge current (50mA or 150Ω).
Higher and constant voltage (8V).

Operating time: 2 years.
ZINC AIR-SALINE BATTERY
Lower discharge current (25mA or 300Ω).
Average voltage: 6V.
Energy density (150Wh/kg).
Operating time: 3 years (lower shelf-discharging).
