As a photographer in today’s digital camera world, knowing the state of charge of your batteries is essential and while most cameras provide a fairly good indication of the state of charge of your battery, it’s never all that accurate. Additionally, spare batteries that you carry with you can be hit or miss as far as charge goes, if you haven’t had them on a charger for a while. Sadly, the majority of chargers don’t provide an actual voltage readout, merely showing a light when the battery is charging/charged. This isn’t always a good thing.
