WebAs a simple guideline, a battery on a portable device having a capacity of 100% typically provides a runtime of ten hours, 80% is eight hours and 70% seven. The service life of a battery is specified in number of cycles. Lithium- and nickel-based batteries deliver between 300 and 500 full discharge/charge cycles before the capacity drops below 80%.
