Lead acid batteries

Lead acid batteries are the best known of all rechargeable batteries. These are the cells used in automobiles worldwide as well as for small-scale energy storage in homes and offices. Advanced lead acid cells have been developed for utility storage applications, the largest being for a 10-MW plant in California.

Lead acid batteries operate at ambient temperature and use a liquid electrolyte. They are extremely heavy and have a poor energy density but neither of these is a major handicap for stationary applications. They are also cheap and can be recycled many times, though they should not be completely discharged as this can cause problems.
