I have an Energizer Model CHDC7 battery charger for AA/AAA batteries.
I'm not sure how to use it. Specifically, when batteries are inserted and plugged in, it displays flashing green lights over all...
Nickel-Metal Hydride (NiMH) batteries are usually charged in pairs in consumer chargers. The CHDC7 can charge two or four batteries at a time. Their position in the charger is important (see the link at the end of this note). Each battery has a separate pair of green LEDs. There are no other LEDs on this charger. The LEDs light up to show the state of charge. Flashing means it is charging. Solid means it has reached that level of charge (ie, 1 LED = half charged, 2 LEDs = fully charged). The batteries will get warm but not uncomfortably so. After some practice you will be able to tell if they are getting too hot (which may signal a worn-out battery which should then be replaced). Like all rechargeable batteries, NiMH batteries have a finite life (measured in number of times they've been discharged and recharged). IMHO, they should also be used and charged in matched pairs. I mark them when I take them out of the box and keep them paired in use and in charging for maximum life. Yes, the devices that use 3 batteries are a pain to deal with. LOL. All details can be found on this Energiser data sheet: http://data.energizer.com/PDFs/chdc7_instructions_english.pdf
P.S. The CHDC7 remains open for charging. Closing it for storage is optional but minimizes the space it takes up.
