The battery is charged with small amount of AC voltage or DC voltage. So if you want to charge your battery with AC source then should follow these steps. The battery is charged with small amount of ...

The following automatic battery-charger design is created with a circuit that could qualify as the simplest window comparator ever built around a single transistor (see the figure). It starts charging ...

Batteries and energy cells lose their capacity as they age. If a cell or battery’s capacity is too low, your equipment may also soon stop working. You can use the circuit in Figure 1 to measure a ...

Apple's battery guide describes lithium-ion batteries as "consumable components" that naturally lose capacity over time. To ...

[Chris] was unhappy with the battery performance of his Rovio. It seems that he’s not alone, so he set out to reverse engineer the battery charging circuit to see if there was a fix. Boy is there, ...
