A. BG 985 Battery Terminal Protectors are corrosion-protection pads or rings fitted to battery terminals to prevent the white/green sulphate corrosion that builds up around battery posts and degrades electrical connection.
A. Clean the battery posts and terminal clamps. Fit a protector pad over each battery post before refitting the terminal clamp. The protector saturates with corrosion-inhibiting compound and protects the connection from atmospheric attack.
A. BG Battery Terminal Protectors are typically replaced at battery replacement or after several years of service. Effectiveness declines as the corrosion-inhibitor saturates — periodic inspection during service is good practice.
A. They significantly reduce terminal corrosion under normal conditions. Severe corrosion can indicate other issues (overcharging, faulty alternator regulator, electrolyte leak, gassing battery) — investigate the underlying cause rather than relying solely on protectors.
A. BG Battery Terminal Protectors are general lead-acid battery protection — suitable for car, commercial vehicle, marine, motorcycle and stationary lead-acid battery installations using standard post-type terminals.
A. Yes — Battery Terminal Protectors are non-conductive and fit both positive and negative posts. Fit one protector per battery post for full corrosion protection.
A. Every product comes with a different guarantee and warranty. Warranty details are shown in the product's tech specs or datasheet where available.
