FEATURES

Your RadioShack Ni-Cdand Nickel Metal Hydride Rechargeable Battery Pulse Charger lets you quickly charge five different sizes of standardnickel-cadmium(Ni-Cd)ornickel-metalhydride(Ni-MH)batteries.

The charger’s four battery chambers let you charge up to four batteries of the same size and type — AAA, AA, C, or D

— at the same time, while the connector inside the charger lets you also charge one 9V battery.

Your charger has these features:

Intelligent Discharge System (IDS) — automatically discharges and conditions cells to a suitable level before recharging, to ensure maximum charging capacity.

Microprocessor Controlled Charging

— automatically detects the battery type and monitors the charging process to ensure the right amount of current is supplied.

Soft-StartCharging— gradually increases charging current when batteries start charging to avoid heat build-up that can reduce battery life.

Fuzzy Logic Intelligent Charging Current Control — automatically senses when a battery is fully charged and switches first to top-off, then tricklecharge, to prevent overcharging.

Red LED Indicator — shows 9V battery charging status.

Liquid Crystal Display — shows AAA, AA, C, or D-size battery charging status.

WARNING: To reduce the risk of fire or shock hazard, do not expose this product to rain or moisture.

If the battery is unsuitable for charging, appears on the display. Do not attempt to charge a bad battery. At the end of a nickelcadmium ornickel-metalhydride battery’s useful life, it must be recycled or disposed of properly. Contact your local, county, or state hazardous waste management authorities for information on recycling or disposal programs in your area. Some options that might be available are: municipal curbside collection,drop-offboxes at retailers such as your local RadioShack store (nickelcadmium only), recycling collection centers, andmail-backprograms.

The checking process drains current from batteries. Therefore, repeatedly checking the same batteries decreases their voltage.

3.To check another battery, repeat Steps 1 and 2. To charge the battery, see “Charging AA/AAA/C/D Batteries.”

CHARGING AA/AAA/C/D BATTERIES

This graph shows the estimated typical fast-chargingtime for different sizes of batteries. Note that charging times increase when more than one battery is charged.

Caution: All batteries loaded into the charger’s chambers must be of the same size and type.

2.Close the cover. disappears.

First, the charger checks the batteries’ condition. Then, if the batteries are more than 60% discharged, the charger’s Intelligent Discharge System (IDS) automatically and completely discharges them. The numeric symbol shows the batteries’ voltage, the bars in the amount-of-charge symbol scan down, and the black triangle in the IDS icon flashes to indicate that the charger is discharging the batteries.

Note: To stop the discharging cycle, you can press DISCHARGE. The charger begins softstart charging. However, repeatedly doing this can reduce the batteries’ maximum capacity.

If the batteries are less than 60% discharged, the charger starts softstart charging, gradually increasing the charging current to the batteries. The bars in the amount-of-chargesymbol scan inward and the black bar in thesoft-startsymbol icon flashes.

Next, the charger begins fast charging. flashes, and the charger charges the batteries up to80–90%

of full capacity. The bars inside the amount-of-chargesymbol scan upward.

The charger then enters the top-offcharging mode to top off the remaining10–20%of battery capacity.andand the top bar inside theamount-of-chargesymbol flash.

Finally, the charger enters the trickle charging mode, providing a very low current to keep the batteries at their fullest until you open the cover. andcontinue to flash andappears. All bars in theamount-of-charge symbol appear.

3.Open the cover and remove the batteries.

4.Unplug the adapter from the AC outlet.

Warning: To prevent damage to your charger and risk of electric shock, always unplug the AC adapter from the AC outlet before you plug it into or unplug it from the charger.

Cautions:

After you unplug the adapter from the AC outlet, wait at least 3 seconds before you plug it into the AC outlet again.

Be sure to remove all batteries before you unplug the adapter to prevent battery leakage that will damage the charger.

23-410.fmPage 8 Friday, August 6, 1999 2:54 PM

Note: The charger can activate or revitalize some chemically dormant batteries. If you have new batteries (or batteries that have not been used for a long time) that cannot be fully charged (charged to more than 60% of battery capacity) singly, recharge them three or four at a time, then discharge them completely through normal use. Repeat this process five times. Then, if the batteries will still not fully charge singly, this means you will always have to charge them three or four at a time.

CHARGING A 9V

BATTERY

Refer to the graph on Page 6 for charging times.

1.After connecting power to the charger, simply push the terminals of the 9V battery onto the connectors inside the charger, matching the polarity symbols marked next to the connectors. The charger begins charging the battery and the 9V charging indicator flashes.

8

Notes:

The cover does not need to be closed to charge the 9V battery.

You can charge up to 4 AA or AAA batteries, or 2 C or D batteries at the same time as you charge a 9V battery.

2.When charging is complete, the 9V charging indicator lights steadily. Remove the battery.

Note: If other batteries are still charging after the 9V battery is fully charged, the 9V charging indicator continues to flash until the other batteries are fully charged.

3.Unplug the adapter from the AC outlet.

Warning: To prevent damage to your charger and risk of electric shock, always unplug the AC adapter from the AC outlet before you unplug it from the charger.

Cautions:

After you unplug the adapter from the AC outlet, wait at least 3 seconds before you plug it into the AC outlet again.

Be sure to remove all batteries before you unplug the adapter to prevent battery leakage that will damage the charger.
