6.12: Battery characteristics
The battery cycle life for a rechargeable battery is defined as the number of charge/recharge cycles a secondary battery can perform before its capacity falls to 80% of what it originally was. This is typically between 500 and 1200 cycles. The battery shelf life is the time a battery can be stored inactive before its capacity falls to 80%.

In subtractive polarity, the voltage (V c) between the primary side (V a) and the secondary side (V b) will be the difference of both high voltage and the low voltage, i.e. we will get V c = V a – V b. In subtractive polarity, if V c = V a – V b, it is a step-down transformer and if V c = V b – V a, it is a step-up transformer.. We use additive polarity for small-scale distribution ...
