Duracell battery chargers can help you get the most out of your rechargeable batteries, but you need to use them properly in order to do so. Some Duracell charger models come equipped with a stock car adaptor as well as the normal AC wall adaptor, but if you've never used a Duracell charger before, it can be a bit confusing. Fortunately, with the right instructions, you can keep those digital gadgets powered without having to constantly buy new batteries.
Put the Duracell NiMH batteries into each of the charging slots of the charger. Be sure only to use the correct size and type of batteries that the manual specifies for your particular charger.
Plug the AC cable into an available wall outlet and then into the 12 V jack on top of the charger itself. You can also choose to use the car charger instead, but only use the one that was supplied originally. You will see that the charger indicator light has turned red, meaning that the batteries are being currently charged.
Watch to see if the red indicator light begins to blink. This means that there is a problem with the batteries taking their charge. It may mean that the batteries are operating abnormally, or that there's an abnormal temperature reading. Either way, the batteries will most likely need to be replaced. If you happen to have a second charger, it may be a good idea to try to charge those batteries in the backup before throwing them out.
Wait for the indicator light to turn green, then remove the batteries and AC cable from the wall or car outlet. Your batteries will now be fully charged.
Batteries that have been sitting for an extended period of time may require two or three charging attempts in order to get optimal results.
