How to Fix a Drill Battery That Won't Charge – Reasons, Fixing and Usage

The drills play a significant role in our day-to-day activities. Battery power some drills while some use electricity from a direct source. However, both serve the same purpose, but the ones powered by a battery are more effective in places without electricity.

Therefore, batteries used in drills must be practical and durable enough to serve their purpose. However, just like any other battery, the drill batteries sometimes fail to charge for various reasons.

We need to know how to fix these issues to avoid being stuck whenever we perform our tasks. I once had an electricity-powered drill that I used when mounting televisions on the walls, but there were power shortages at times.

Therefore, I had to buy a battery-powered drill to remain as the backup for the others. It works well and serves the same purpose. However, one day the battery stopped charging, and I knew nothing about it. I had to get help from experts to tackle the situation. Therefore, I will help you today to know how to tackle it.

Why won't a drill battery charge?

Most drills use lithium-ion batteries that are wondrous invention and lightweight as well as lo9ng lasting batteries. However, it is frustrating when the battery fails to recharge. You stick the charger into the charging slot, and boom, nothing happens.

The battery might fail to charge because you are using the wrong charger. Some chargers are recommended by the manufacturer that are effective for the drill battery. Also, using a faulty charger will mean that the battery will not charge.

Therefore, you must ensure that all parts of the charger are in good condition and that the charger you are using is recommended. The battery might also not be fully locking into the charger; thus, the two's contact is lost, meaning no power transmission.

You need to check if the backup battery is charging when placed on the same charger. If the backup battery is not charging, then the charger is faulty. However, if the battery is charging, then your battery might be dead.

Furthermore, copper shunts can be formed inside the battery's cells, leading to partial or total electric short. When you charge such a battery, it will not charge or become unstable, causing excessive release of heat or other anomalies.

How do you fix a drill battery that won't charge?

You cannot throw away a battery because it failed to charge. The battery might not even be the problem, but it will be expensive for you to replace batteries every time they stop charging. Therefore, I have detailed steps for you on how to fix this issue.

You will need the following tools:

• An AC adapter.

• A multimeter and the battery that isn't charging.
  

Procedure

• Cut off the end of the Ac adapter. You need to use an old adapter that you do not need anymore.

• Separate and remove the cover of each one up to about an inch long. The black wire is negative, while the striped or solid white wire is positive.
  

• Unscrew the cover holding the batteries together. Ryobi batteries have star-shaped screw heads.
  

• Other batteries have hidden screws under a piece of plastic. Pry the plastic cover off to get at the screw underneath.
  

• Pull the top cover off the battery.
  

• Remove the two plastic side pieces, then lift the battery pack out.
  

• You then set the multimeter to read volts. For a 12-volt battery, choose the 14 volts setting that will give you the most accurate reading.
  

• Attach the red clip to the +ve terminal and the black clip to the -ve terminal. Read the voltage displayed on the multimeter.
  

• Plug your Ac adapter into a socket and, using the wires, boost the battery. You just need to attach the black wire to the negative terminal and the white wire to the positive terminal. Do it on and off for about a minute.
  

• You should then test your voltage on your battery pack and ensure that it is higher than it was before boosting.
  

• Reassemble the plastic covers on the battery pack and set the battery on the charger to see if it will charge. If you get a red flashing light and the battery won't charge, repeat the procedure.
  

• Repeat the boosting and testing until the battery s recognized by the charger and get a green light.
  

However, before doing anything, ensure that your charger is working. At times, the charger might be faulty, and you end up doing the above procedure for nothing. Therefore, you should try another charger before doing anything.

If all the processes fail, then you need to consider the age of your battery. If it has lasted for an extended period, then you should replace it immediately.

How do you use a drill battery properly?

Like any other battery, a drill battery needs to be well taken care of for durability and effectiveness. With proper storage and care, you will be amazed by how effective these batteries can be. Therefore, here are the dos and don'ts to help you get the best out of a drill battery.

Keep the battery charged: ensure that the batteries are charged as soon as you notice a decrease in power. Most batteries last long when recharged at 70 percent capacity.

Use the battery regularly: keeping the battery idle for a long time will lose its ability to hold a charge. If you regularly use a tool, consider a plug-in version or plan to recharge the drill battery before working.

Keep the battery cool and dry: batteries last longer if they are kept dry and cool environment. You should not necessarily store the battery.

Please charge the battery completely: you must charge the battery to its full capacity before unplugging the charger. Most chargers have lights that show when the battery is fully charged.

Do not fully discharge the battery: draining the battery can permanently damage the battery and shorten its life. Recharge the battery as soon as your tools start to slow down. Do not deep drain the battery unless you are using a NiCd battery.

Do not overheat the battery: Heat is a dangerous factor to rechargeable batteries, and it can cause the battery to explode. Therefore, if the battery gets too hot, unplug it from the charger and leave it to cool down before recharging or using it.
