AGM Replacement Battery for Electric Fence, 12V 5Ah

Digital Battery Tester 6-20 V – reliable battery checks for fence energisers The digital battery tester lets you check the batteries of your electric fence energiser in seconds. It shows whether your fence battery still holds enough charge, helping you avoid weak fence voltage and keep livestock safely contained. The tester measures both the open circuit voltage and the voltage under load, revealing hidden charging issues that a simple glance at the battery can't show. Since it needs no internal battery of its own, it's always ready to use in the barn or out on pasture. After a short time, the tester switches off automatically to protect the battery being tested. Overview: Test range from 6 to 20 volts for common fence batteries Displays open circuit voltage and load voltage separately Detects weak or undercharged batteries early No internal battery required – ready to use instantly Automatic shut-off (display shows "OF") protects the tested battery Compact, handy design for everyday farm use Technical Data: Test range: 6 – 20 volts Colour: Black Dimensions: approx. 21.7 x 9 x 4.6 cm Weight: approx. 0.114 kg Country of origin: Germany Included: 1x Kerbl Digital Battery Tester 6-20 V FAQ: Does the tester need its own battery?No, the device works without an internal power source and is ready to use immediately. What does "OF" on the display mean?After a short measuring time, the tester switches off automatically and shows "OF" to protect the tested battery. Which batteries can I test with it?All common fence energiser batteries within the 6 to 20 volt range.

Solar power for your horse paddock: AKO Sun Power S 250 solar electric fence energiserThe AKO Sun Power S 250 is a compact solar electric fence energiser for horse paddocks, turnout areas and smaller fence systems without vegetation. The fixed 3 W solar panel keeps the 12 V AGM battery with 5 Ah charged, so you do not need a socket on the pasture. Energiser, battery and panel form one unit that you set up directly by the fence or attach to a post.An integrated charge control with microcontroller monitors the battery and keeps the fence live even through longer rainy spells, with a full battery for up to 2 weeks without sun. If the battery voltage drops below 11,2 V, the deep discharge protection kicks in and the red LED flashes. Using the supplied 230 V power supply you can recharge the battery when needed or keep it on maintenance charge over the winter.Overview:Horses stay safely in the paddock: under load there are still 2.800 V on the fence, around 2.500 V is considered the minimum for horsesUp to 3 km of fence without vegetation, still around 0,7 km with medium vegetation, so cut back grass and branches regularlyCheck the voltage at the end of the fence from time to time with a fence tester, so you notice early when vegetation or an insulator drains currentEasy mounting: the guide channel in the housing takes the post, so the energiser sits firmly on the fenceWith the on/off switch you can work on the fence without current, with no need to disconnect cablesShort electric pulses are unpleasant but harmless; put up the enclosed warning sign clearly visible along public pathsTechnical data:Battery: AGM battery 12 V, 5 AhSolar panel: 12 V, 3 W, fixedMax. voltage: 10.500 VVoltage at 500 ohms (under load): 2.800 VMax. stored energy: 0,40 JMax. output energy (pulse on the fence): 0,25 JTheoretical fence length: 6 kmMax. fence length without vegetation: 3 kmMax. fence length with medium vegetation: 0,7 kmPower consumption: 10 to 22 mADeep discharge protection below 11,2 V battery voltageLEDs: green (operation), blue (solar mode), red (battery warning)Integrated lightning protectionOn/off switchEarth rods required: 1x 1 mWarranty: 5 years on the energiser, 6 months on the batteryUse: horse paddocks and small fence systems without vegetationMade in GermanyScope of delivery:1x AKO Sun Power S 250 solar energiser with fixed solar panel 12 V, 3 W1x AGM battery 12 V, 5 Ah1x Power supply 230 V1x Connection cable for fence and earth1x Earth rod1x Warning signQuestions & answers:Is the S 250 also enough for sheep, goats or cattle in winter coat?Probably not. For animals with dense coats or wool at least 4.000 V should be on the fence, while the S 250 delivers 2.800 V under load. For these animals you are better off with a stronger energiser with more joules.What do the 0,40 joules tell me, and is that enough?The 0,40 J is the energy the energiser stores for every pulse, and 0,25 J of that reaches the fence as a shock. This pulse energy determines how clearly the animals feel the fence and how well it copes with vegetation, the voltage alone says little about it. For short, clear horse fences that is plenty, for long or heavily overgrown fences an energiser with more joules is the better choice.How many earth rods do I need and where do I put them?For the S 250 one earth rod with a length of 1 m is enough, which you drive fully into moist ground, at a distance from buildings. If the ground is dry or sandy, set additional rods at least 3 m apart and connect them to each other. Weak earthing is one of the most common causes of too little shock strength on the fence.

Mobile grazing without mains power: Agrarzone S 25 solar electric fence energiserThe Agrarzone S 25 is a solar electric fence energiser for small, mobile paddocks without vegetation. The 3 W solar panel automatically recharges the 12 V AGM battery (4 Ah) in daylight, so you do not need a mains connection on the pasture. This lets you reliably fence in cattle, horses and dogs on rotational pastures, paddocks or in the garden.Thanks to intelligent battery management, the energiser keeps working in bad weather, for up to 2 weeks with no sun at all. The deep discharge protection switches off below 11,2 V and so protects the battery. With the supplied 230 V power supply you can easily recharge the battery in winter or after longer storage. The S 25 is not designed for electric netting.Overview:Enough voltage for cattle and horses: under load there are still 2.800 V on the fenceNo mains connection needed, solar panel and battery power the fence right on the pastureFence length up to 3 km without vegetation, up to 0,7 km with medium vegetationSpot problems straight away: LEDs for operation, solar charging and battery levelEconomical to run, in standby the energiser draws only approx. 0,2 mAShort electric pulses: unpleasant but harmless; put up a warning sign along public pathsTechnical data:Battery: AGM battery 12 V, 4 AhSolar panel: 12 V, 3 WMax. voltage: 10.500 VVoltage at 500 ohms (under load): 2.800 VMax. stored energy: 0,40 JMax. output energy (pulse on the fence): 0,25 JTheoretical fence length: 6 kmMax. fence length without vegetation: 3 kmMax. fence length with medium vegetation: 0,7 kmPower consumption: 10 to 22 mAStandby current: approx. 0,2 mAIntegrated lightning protectionEarth rods required: 1x 1 mSuitable for: cattle, horse, dogScope of delivery:1x Agrarzone S 25 solar electric fence energiser1x Solar panel 12 V, 3 W1x AGM battery 12 V, 4 Ah1x Fence connection cable1x Earth cable1x Earth rod1x Power adapter 230 V1x Operating instructionsQuestions & answers:Is the voltage enough for horses and cattle?Yes, for small paddocks without vegetation. Under load the S 25 still delivers 2.800 V, and at least around 2.500 V is recommended. Check the voltage regularly with a fence tester, because vegetation on the fence makes it drop.How long does the energiser run in bad weather?With a full battery, up to 2 weeks with no sun at all. Vegetation on the fence increases power consumption and shortens this time. In winter you simply recharge the battery using the supplied power supply.How do I earth the energiser correctly?For the S 25 one earth rod with a length of 1 m is enough. Drive it as fully as possible into moist ground, away from buildings. In dry ground, additional earth rods spaced at least 3 m apart and connected to each other will help.
