Ni-CD: Memory effect with small capacity
Ni-MH: Memory effect Small capacity large
Lithium ion: No memory effect body thin capacity, due to different electrode materials, electromotive force is 3.6V, 3.7V two kinds. Lithium battery performance is the best of the existing types of batteries, small size, light weight, large capacity. Widely used in digital cameras, notebook computers, mobile phones and other electronic products.
Lead storage: electromotive force of about 12V, lead-acid battery can be used repeatedly charge, electrolyte is sulfuric acid solution, internal resistance is very small, widely used in automobiles, motorcycles.
Lithium iron: Electric power is more adequate, safer and lighter, the main direction of future electric vehicle development.
Generally, the same type of rechargeable batteries, the larger the volume, the larger the weight is also large.
