The CHARGEminders unique microprocessor circuitry works with your existing overnight charger s to prevent overcharging It also safely maintains the charge on your batteries indefinitely by converting your charger into a pulse trickle charger The gentle pulse trickle effect not only gives you a visual indicator but tests have proven it is actually better for your NiCd battery s life than conven tional trickle charging The CHARGEminder is simple to use since it just plugs into the wall outlet before your charger There is nothing else to buy and no soldering is required Simply plug it in and go For obtaining the maximum benefit from this product please read the following instructions very carefully I INSTRUCTIONS IMPORTANT NOTE DO NOT PLUG ANY SURGE PROTECTING STRIPS REGULAR POWER STRIPS WITH BREAKERS ARE Ok OR ANY OTHER TYPE OF DEVICE EXCEPT FOR OVERNIGHT NiCd BATTERY CHARGERS INTO THE AUTO TRICKLE ADAPTER Before operating the unit the CHARGEminder must be set to match the SPEED of the battery charger Pick the time in hours on the CHARGEminder that either exactly matches or is slightly lower than the time recommended by your chargers manufacturer INSURING COMPATIBILITY PLEASE READ The CHARGEminder IS COMPATIBLE with almost all inexpensive or dumb chargers To insure compatibility prior to use the following test must be made Note that this test does not require the use of the CHARGEminder STEP 1 Fully charge y
3. at the end will insure a full charge Push and hold the start button on the face of the unit for more than 3 seconds Continue to hold until the lights indicate the number of hours your charger is rated When you see the proper time selected immediately let go of the button NOTE For 3 5 and 7 hour timing there will only be one RED light on at a time When one light is on use the number ABOVE the RED light When the GREEN light on the right comes on use the number BELOW the RED light to indicate the number of hours STEP 3 Push Start to begin charging Once the CHARGEminder is set as shown above the CHARGEminders RED light will blink on and off to indicate it is in TRICKLE or maintenance charge Momen tarily push the start button to start a charge cycle Note that during the charge cycle the red light will stay on and not blink The RED light and the charger you have plugged in will remain ON for the pre selected number of hours It will then automatically go back to trickle until you push the start button again If for any reason you want to abort the charge timer and go back to trickle just momentarily push the start button and you will see the CHARGEminder s lights blinking again NOTE For battery safety reasons a prolonged power blackout will reset your CHARGEminder to the 3 hour setting Please verify the number of hours before you push the start button II FUSE REPLACEMENT If your charger does not work when connected
4. to the unit you may have exceeded the maximum 120 watt capacity and blown the fuse To check or replace the fuse you will need to UNPLUG THE UNIT and carefully remove the four screws on the box The fuse may be removed by gently pulling it away from its clips Be sure to replace with a 1 Amp Fast blowing fuse only Carefully reassemble the unit before plugging it into a power receptacle Il SPECIAL NOTES WHAT IF CHANGE MY MIND AND DON T WANT TO QUICK CHARGE MY BATTERIES To stop the charge timer and go back to trickle mode prematurely simply push the switch once again The charger will go back to trickle mode WHEN SHOULD I CHARGE MY BATTERIES When using chargers that fully charge your batteries in less than 12 hours or less DO NOT initiate a full charge period to a fully charged battery Best results are obtained by using your batteries until they just begin to die out before placing them back on charge or leave them on trickle as described below When using 16 hour or overnight chargers you may initiate a full charge period even if there is a residual charge in the battery Overnight chargers are much more forgiving to overcharging However do not initiate a full charge period to a fully charged overnight battery more than twice per week IF YOU ARE NOT IN A HURRY In most cases the trickle rate alone will fully charge your discharged batteries in about three to four days If you are not going to need your batteries charged right a
