Hotline P525 Buzzard Energiser (12v)

The Hotline P525 Buzzard 12v Energiser is a powerful 2.4 joule unit recommended for use on long boundary fencing applications where it is not possible to use a 220v mains electricity unit. On long distances of fencing or permanent fences several earth stakes may be required for effective operation.


It is a very powerful battery fencer with two levels of output so the fencer should be initially set to high to allow the animals time to respect the fence, thereafter it can be set to low.

Can power up to 20 sheep nets or 8 poultry nets, or up to 25km of galvanised wire.

Although a 12v 85Amp/hr Leisure Battery will operate the unit very well, if using on long runs of fencing on high power most of the time we recommend a rechargeable battery of a least 100amp/hr. Battery will need recharging every 2-4 weeks.

There is a 2 year warranty on all Hotline energisers. This energiser will be despatched directly from Hotline so please allow a few extra days for delivery.

This 85 amp/hr, re-chargeable 12v Leisure Battery comes with a built-in charge level indicator and carry handle. It also has double terminals so it can take a trickle charge whilst being used. Heavt Duty battery for leisure and marine use.

For use with any 12v Electric Fence Battery Energiser e.g. Hotline Hobby Energiser, Hotline Gemini, Gallagher BatteryMaster, Wolseley Midge etc.

We always recommend the use of leisure-type batteries with electric fencing. They are designed to be discharged and then re-charged whereas car batteries are not. This battery should have a life of 200 cycles so will last quite a number of years.

Although a charge will last approx 6 weeks we do recommend that they are recharged every 2 weeks or so to keep the battery in best condition. This battery has a depth of discharge of 70% and we have found that if allowed to discharge fully it could damage the plates and it will be very hard to get it to take a full charge properly again. Also, we do recommend with this battery that at least a 7 amp battery charger be used if possible.
