Applies to lead-acid batteries of the enclosed, pure lead positive, pasted plate type, designed specifically for floating service in a stationary mode. These batteries are designed to yield service lives as follows: (a) For 10-hour rate batteries - approximately 15 years. (b) For 1-hour rate batteries - not yet verified by experience in the field. However, it is anticipated that adherence to the relevant parameters of this Standard should ensure service lives equivalent to the 10-hour rate design. This specification includes requirements for batteries of the above types incorporating cells of either the 10-hour rate or 1-hour rate design and their accessories, but does not apply to Plante, tubular-positive plate or lead-calcium type batteries, or to those batteries designed for planning routine cycling.
