Charging Drill Batteries

Charging new Drill batteries can be frustrating. Most people have been told that they should charge their new battery before using it. Some of you already know that trying to charge the battery first does not always work. Depending on how long the battery has been sitting on the shelf is directly related to how much energy is left in the battery pack. Batteries are not shipped fully charged, but they do get an initial charge from the factory to energize the cells and test the integrity of the pack. If you receive a new or recently built battery pack, your charger may not recognize that the battery needs to be charged.

Drill Battery Charger

Some chargers, sample the voltage of a battery pack to determine weather or not the pack needs charging and if it see the voltage where it should be like in the case of a freshly manufactured battery pack, it will not start to charge. The charger believes the battery is already at full charge and does nothing or it may light up momentarily and the stop. What is needed is to put the pack into the drill and run it down a little and then try putting it back into the charger. If the charger still will not charge the battery, then you may have a defective charger, but try this first.

Also,the main reason that Drill batteries go bad is they're run down too low before recharging.  This will not be the case with a brand new battery.  Brand new batteries, right out of the box can be used until you experience a slowing of the drill at which time you should place it on the charger.  If you run a battery down continuously over a prolonged period of time , your can cause a polarity reversal in some cells, which is why they fail to recharge to their operating voltage over time.

DEWALT DW9116 7.2-Volt to 18-Volt Pod Style 1 Hour Battery Charger Overview

This is an amazing little charger that literally breathes new life into your failing DeWalt batteries. It revitalizes everything from 9.6 volts through the big 18-volters, but what's so great about this charger is that not only can it be used as a standard quick charger, but if you leave a worn-down battery in for four to 10 hours, the charger conditions the battery with a tune-up mode, and at completion, it automatically converts to trickle charge, so you'll never damage a battery by leaving it in the charger too long. Diagnostics with LED indicators give you the battery status at a glance: charged, charging, power line problem, replace pack, and battery too hot or too cold. It's got a small footprint, which is always a plus, and the price is look-twice-and-rub-your-eyes cheap.
