A spare/replacement battery is not only great to have in case of emergency – should your battery become damaged in any way – it’s also great for prolonging the use of your heat gun.If you’re taking on a long project, you can use the battery that comes with your tool whilst charging the other, ensuring it’s ready to be replaced when the first battery runs out – minimising downtime and maximising productivity.Compatible with 18V Cordless Heat Gun (3500085)SKU: 3500086
