How To Get A Higher Battery Capacity. C- and E- rates In describing batteries discharge current is often expressed as a C-rate in order to normalize against battery capacity which is often very different between batteries. A battery that appears to have a high capacity on a spec sheet may actually perform poorly if the current drain for the application is higher.
In reality however the way the battery is discharged has an impact on the actual battery life. With lithium-ion batteries the capacity diminishes slightly with each complete charge cycle. The mAh ratings will help provide you with a longer run time between recharges.
To obtain a reasonably good capacity reading manufacturers commonly rate alkaline and lead acid batteries at a very low 005C or a 20-hour discharge.
C- and E- rates In describing batteries discharge current is often expressed as a C-rate in order to normalize against battery capacity which is often very different between batteries. As you might remember from our article on Ohms law the power P of an electrical device is equal to voltage V multiplied by current I. Apple lithium-ion batteries are designed to hold at least 80 of their original capacity for a high number of charge cycles which varies depending on the product. The more amps you draw from a battery the more the.
