Electric fence batteries should never be standard 'car batteries' as they are not designed to be constantly charged and discharged; they will die very quickly...
This 105Ah sealed deep cycle electric fence battery is significantly larger and longer lasting than the standard Hotline 33Ah and 75Ah batteries, which extends the time between charges. When using, for example, the Hotline HLC120 energiser, you can expect about 14-days life from a 75Ah battery, but about 21-days from the 105Ah battery. The 105Ah Numax fence battery is fully sealed, maintenance-free and guaranteed for 3-years and is one of the best batteries available for heavy duty applications such as electric fencing.
NOTE: All batteries, regardless of type, have a longer service life if they are not fully discharged every time they are used. Therefore, we recommend that you try to change / recharge your electric fence batteries before they run out completely. For example, if your battery will work with your energiser for 10-days, we would suggest changing it over or recharging it after 7. You could also connect a solar panel to the battery to help maintain it and extend the life between recharges.
