Various factors in comparing batteries include their energy storage, specific energy capacity, responsiveness, power bandwidth, operating environment, efficiency and installation. Some types of batteries offer better shock and vibration tolerance, lower operating cost and maintenance demands like cleaning the corrosion build-up on terminals, service life, temperature extremes and charge time.
Also, consider the battery’s mode of disposal. Nickel-cadmium and lead acid batteries contain hazardous materials, so avoid disposing of them in landfills. Nickel-metal-hydrate and lithium batteries are not harmful to the environment, and thus can be disposed of alongside other regular household waste. Lead- nickel and lithium-base batteries, meanwhile, require frequent recharging to replace power lost.
