How to Replace a 14.4 Volt Coleman Drill Battery
How to Replace a 14.4 Volt Coleman Drill Battery
Coleman cordless drills use 12-, 14.4- or 18-volt rechargeable batteries to power them. With correct usage, the Bosch drill battery packs have a lifespan of approximately two years. Once the batteries die, they must be replaced with a Coleman battery pack using the same voltage as the old battery. For example, replace a 14.4-volt battery with only a 14.4-volt battery. After the battery pack is replaced, it must be fully charged to be used.
Unplug the Coleman drill from the power source by removing the plug from the outlet. Disconnect the charging cord from the Coleman drill by pulling the cord from outlet, located on the backside of the drill. Never change the battery while the drill is plugged into a power source.
Lay the drill flat on a table. Push the release buttons on both sides of the battery pack inward. The battery pack is located below the Coleman drill handle.
Pull the battery pack downward for to remove it from the Coleman drill.
Position the battery so it is aligned with the battery handle. The back side of the battery will say 14.4V on it. The back of the battery will be pointed toward the back of the cordless drill. Slide the new battery pack upward to insert it. Once properly inserted, the battery will lock into place. If not properly inserted, it will not lock into place and will fall out.
Plug the charging cord back into the charging outlet on the Coleman drill. Plug the opposite end of the charging cord into an electrical outlet. The battery will begin charging.
How to Rebuild a Dewalt 14.4V Battery
The DeWalt 14.4-volt battery is one of a large range of batteries designed for that company's line of more than 200 cordless power tools. It is made from 12 nickel cadmium (NiCad) cells, each producing 1.2 volts to enable the battery to produce 14.4 volts once wired in. If you find your battery doesn't hold its charge, it's less expensive to rebuild it rather than buy a replacement
Remove the 14.4-volt DeWalt battery from the power tool and place it on a workbench.
Remove the battery cover using a Phillips head screwdriver to unscrew the six screws. That number may vary depending on the type of battery.
Use a small screwdriver to pry out each of the12 NiCad cells from their battery compartment. Some are soldered as this provides a better connection and helps stop the cells from shorting. If they're soldered, heat a soldering iron and touch a soldered cell terminal with the soldering iron until the solder melts. Remove the soldering iron and quickly pry the cell away from the connection before the solder hardens. You must do this on all 12 cells.
Place the 12 NiCad cells in a clear plastic bag so they are visible. Dispose of the cells in a battery recycling unit and not in your regular trash.
Insert the replacement NiCad cells into the battery compartment. Either push them in place or, if the old ones were soldered, heat a soldering iron. Touch each cell terminal with the soldering iron and solder. Allow a small amount of solder to melt, then remove the soldering iron and solder and let the solder solidify and cool. Repeat that process on each cell terminal.
Let the battery pack cool. Replace the battery cover but don't tighten the screws with excess force.
Put your battery on charge for an hour to ensure that all the cells are fully charged.
Insert the battery into your power tool.
