Lead–acid battery fundamentals
The common design of lead–acid battery has ''flat plates'', which are prepared by coating and processing the active-material on lead or lead–alloy current-collectors; see Section 3.4.1. One alternative form of positive plate has the active-material contained in tubes, each fitted with a coaxial current-collector; see Section 3.4.2 .
