In this case, with a 100 μm lead plating, the calculated weight of the titanium-based grid is 3.04 g. In contrast, the mass of the …
Lead-Acid Batteries | Capaciton 2024
The biggest difference between these batteries is the cell design and the amount of lead and other materials used. The fewer cycles a battery is designed for the cheaper the production cost – from a user perspective a 700 cycle battery should of course be less than half the price compared to a 1,500 cycle battery.
