when the battery has cooled.

Allow batteries to cool before placing into a product to be used.

I cannot change modes.

Within 8 seconds of installing a battery, press and hold the MODE button for 5-10 seconds to change modes.

Why does my display flash a number?

Your station will flash when first plugged in. If it continues to flash your a/c cord may be defective.

What type of batteries can I charge?

NiMH (Nickel Metal Hydride) or NiCd (Nickel Cadium) rechargeable batteries only may be used in this product. Charging other types of batteries may result in failure of the charger.

My battery reads “Null”.

This charger requires at least .9v in the battery in order to charge it. If the battery is depleted below that point, you will not be able to charge it on this battery charger.

Batteries will self-discharge if left unused. If unused for 30-60 days they may completely deplete of power after long storage.

NiMh batteries should be stored fully charged and recharged every 30 days to keep in peak capacity.

NiCd batteries should be stored fully discharged. Do not “store” batteries in the charger.

How do you charge the smaller AAA battery?

Just place it in the smaller tabs in the charger.

You may want to invest in a small charger/holder that will bring the battery back above .9v when attached for 20-30 seconds. The battery can then be charged in our charger.

Why do my new batteries not show full capacity?

Due to storage and shipping times, you should charge your batteries fresh out of the package. All rechargeable batteries need to be used in a product “under load”, then charged, used, charged, at least 5 times or more to reach full capacity. Batteries sitting in storage may lose some charge over time.

It is not recommended to “condition” batteries until after they have been charged and used 10 times.

As you use your batteries they will gain greater capacity and last longer. It is common for your batteries to run down quickly at first.

Storing batteries

Store between 40 and 80 degrees F. Do not refrigerate.
