Advantages Disadvantages
Affordable Bulky size
More resistant to extremes in temperature or overcharging Usually heavy
Large current capacity Need to be upright to function well
A diverse range of sizes and specifications available Can get damaged by losing charge
Advantages Disadvantages
High cycle count when properly maintained Low specific energy when compared to other types of batteries
Can be charged ultra-fast Has “memory effect” and thus needs to be fully charged before use or it won’t charge to full capacity on subsequent charges
Excellent load performance Needs periodic full discharges
Can be stored while discharged with a long shelf life High capacity for self-discharge
Simple to store and transport because of their small size Has low cell voltage of 1.20V
Good performance at low temperatures Requires several cells if a high voltage is needed
A diverse range of sizes and specifications available Cadmium is toxic and hard to dispose of safely
