4200 and 4600 stick pack instructions

When you first receive your pack(s) you should charge them right away!

YOU MUST CLOSELY MONITOR THE PACKS WHILE CHARGING ON THE FIRST CHARGE! YOU SHOULD ALWAYS START THE FOLLOWING PROCEDURE IN A CLIMATE CONTROLLED ENVIRONMENT WITH THE BATTERY PACK AND CHARGER AT ROOM TEMPERATURE! (70-80 DEGREES F, 21-27 C)

First Charge: Charge the battery pack at 3 amps. If your charger has adjustable peak detection start by setting the peak detection value on your charger to .03 or 30 Millivolts. Higher charge rates/peak detection values on this cycle may cause the cells to vent which will shorten the life of the pack. Only use a charger specifically designed to charge Ni-Mh cells! If your charger does not have adjustable peak detection make sure that the temperature of the battery pack does not exceed the high limit (130F, 55C) outlined below. If the charger shuts off before the lower limit (115F, 46C) is reached the battery is not fully charged and will not perform as well as a fully charged pack.

If your charger does not shut off before the temperature of the middle two cells reaches 130 degrees F unplug the pack from the charger and consult the manufacturer! If your charger shuts off lower than 115 degrees F then increase the peak detection to the next higher value. Once your charger shuts off at a temperature between 115-130 degrees F you have selected the proper value.

After the first charge you can charge the pack at 4-5 amps.

For short term storage (less than a week). After use and before storage make sure there is at least a 10% charge in the pack. If you are unsure it is always a good idea to put 5-10 minutes of charge back into them.

For long term storage . If you do not plan on using this pack again for more than a month, you should fully charge it before putting it away. You should repeak the packs every 30 days to prevent dead cells*. After long term storage, the pack may false peak several times before taking a normal charge. You should expect some decrease in performance after long periods of inactivity.

*If Nimh cells are allowed to reach 0 volts they will suffer irreparable damage. Therefore it is imperative that you regularly check them and recharge them as necessary.
