Lead-acid batteries are rechargeable batteries found in cars, trucks, boats, forklifts, and UPS systems. Each battery contains several kilograms of recoverable lead plus sulphuric acid, which makes them both valuable and hazardous. In New Zealand, recycling lead-acid batteries is regulated — they must be transported upright, in leak-proof containers, and cannot be disposed of in general waste. The lead plates, terminals, and grids inside are smelted down and recast into new batteries and other lead products. At endless metals in Auckland, we accept car and truck batteries and pay competitive rates. Never attempt to break open a battery yourself — the acid is corrosive and the lead dust is toxic.
