Sony AC-VQ850D Charger Buyers Guide

Sony AC-VQ850D Charger obviously come in a range of shapes and sizes to match the variety of rechargeable batteries available.

However, certain types of rechargeable battery, NiCad ("Nickel Cadmium") batteries, for example, need proper care and conditioning before use. Conditioning, in this sense, means fully charging and discharging batteries for a few cycles and advanced charger allow this to be achieved with a minimum of fuss. Failure to discharge batteries fully can result in a so-called "memory effect," whereby a battery "remembers" the level to which it was discharged previously and cannot be discharged below that level on subsequent occasions.

Rechargeable batteries should never, repeat never, be charged for longer than recommended by the manufacturer; there is a serious risk of fire, or even explosion if they are. Some charger therefore include a microprocessor, which detects when batteries are fully charged and automatically switches off the Sony AC-VQ850D Charger when they are. This is an extremely useful feature because it means that you can plug in your Sony AC-VQ850D battery charger somewhere out of sight and effectively forget about it until you need to use the battery again.
