Lead acid battery advantages & disadvantages
Although lead acid batteries are widely used because they have a number of distinct advantages, they also have several major disadvantages. All these need to be considered when deciding upon whether to use this technology or not.
Lead Acid Battery Advantages
1, Mature technology
2, Relatively cheap to manufacture and buy (they provide the lowest cost per unit capacity for rechargeable cells)
3, Large current capability
4, Can be made for a variety of applications
5, Tolerant to abuse
6, Tolerant of overcharging
7, Wide range of sizes and specifications available
8, Many producers worldwide
Lead Acid Battery Disadvantages
1, Fails after a few years use lifespan typically 300 - 500 cycles
2, Cannot always be used in a variety of orientations
3, Corrosive electrolyte (can cause burns to people and corrosion on metalwork)
4, Lead is not environmentally friendly
5, Acid needs disposing of with care
6, Not suitable for fast charging
7, Must be stored in charged state once electrolyte introduced
8, Typical charging efficiency only around 70%

Varieties of Lead Acid Batteries
Over the years battery manufacturers have introduced a range of additives such as Calcium, Antimony and Selenium to improve various battery performance parameters. For the same reason, different cell and battery constructions have been developed to optimise various aspects of battery performance.
Lead Calcium Batteries
Lead acid batteries with electrodes modified by the addition of Calcium providing the following advantages:
1, More resistant to corrosion, overcharging, gassing, water usage, and self-discharge, all of which shorten battery life.
2, Larger electrolyte reserve area above the plates.
3, Higher Cold Cranking Amp ratings.
4, Little or No maintenance.
Lead Antimony Batteries
Lead acid batteries with electrodes modified by the addition of Antimony providing the following advantages:
1, Improved mechanical strength of electrodes - important for EV and deep discharge applications
2, Reduced internal heat and water loss due to gassing, however the water loss is still greater than the equivalent loss in Lead Calcium batteries.
3, Longer service life than Calcium batteries.
4, Easier to recharge when completely discharged.
5, Lower cost.
Lead Antimony batteries have a higher self discharge rate of 2% to 10% per week compared with the 1% to 5% per month for Lead Calcium batteries.
