SPARE BATTERY 6V/4AH FOR S10/S16/S20 GALLAGHER 2M1847

Locate the battery compartment on your S10, S16, or S20 Gallagher energiser and slide out the old 6V/4AH battery. Insert the new battery ensuring the positive and negative terminals match the connector — forced connections will damage both battery and unit. Slide the battery holder back into place and test the energiser on a known fence to confirm it's working before relying on it for stock control. Tips: Check your battery terminals for corrosion or loose connections before assuming the battery is dead — a poor connection wastes money and leaves you with a dead fence when you need it most. Store spare batteries in a cool, dry place away from direct sun, as heat kills battery life faster than anything else. During winter months, check your battery more frequently as cold weather reduces battery output by up to 30 percent.
