Ryobi Battery Won’t Charge – Fix

The Ryobi battery may not charge for various reasons. Here we are going to look into some reasons why the battery might not charge and try to solve the issues.

The Ryobi battery can get in sleep mode. This can happen if the juice inside the battery is used up. So, the power level becomes empty and the battery goes into a hibernation state. You can fix this problem with ‘mini charges. This you can do by putting the battery on the charger for a few seconds and then removing it, even before the light on the charger flasher. You should do this for 30 minutes. You will then see that the battery is reviving automatically. Another way to fix this problem is to connect the battery to a power source, like a DC power source or another battery. Just makes sure that the contacts are connected properly; that is positive with positive and negative with negative. Leave the battery like that for 5 to 10 minutes. You can also get a multimeter to check the voltage of the battery. Your charger should have a voltage of 18 or higher. Then you must check the battery. The voltage should rise when you ‘mini charge’ the battery. 

The charging temperature can be a problem. So, you must check the temperature. The ideal charging temperature for the Ryobi lithium battery is 410F to 1130F. So, if you should try to charge the battery at this temperature by taking it to a warmer or cooler place. 

You must check the terminals and see if the contacts on the charger and the battery are in a good state. If it’s dirty or rusted then the charge won’t pass through and that’s probably the reason why the battery isn’t charging. If dirt has built up then you must use a wipe or wire brush to get rid of the dirt. If rust has formed then you should use sandpaper to scrub the area.

If all these attempts fail then you must take go to a repair store to fix it. The Ryobi batteries usually have a 3 years warranty. So, if you incur any problem during this period, the manufacturer will replace the battery with a new one.

Ryobi Battery Charger Not Lighting Up

Sometimes you may notice that there is no light on the charger when you plug it in. Sometimes you may notice the green light flashing only for a few seconds and then turning off. One reason for it can be due to bad contact. You must check whether the battery fits into the slot of the charger properly. Then use a multiplier to check the voltage. You can try another battery and see if the charger works this time. The battery charger may not light up if the battery goes into sleep mode. So, you can check the voltage, take the charger to a different power source, and check. Sometimes, even if the light is not on, the battery may be charging. If you can’t fix the issue then you should take it to a repair shop.

Jump Start Ryobi Battery

Your battery may get overcharged. In such a case the charging circuit of the battery may prevent the battery from further charging. If you want to recover the battery, you need to ‘jump-start’ the battery. This can be done by using another battery that is in good condition. You should connect the good battery with the problematic one for only a few seconds. The bad battery will get charged temporarily.  You must first remove the outer casing of the battery pack to get hold of the individual batteries. You should then check the positive and negative terminals of the battery pack. By using a multimeter you can check the voltage of the battery. At this stage, it will be very low. Then use a good battery and connect it with the bad one making sure that the positive is connected to the positive and the negative to the negative. You must connect directly to the batteries. Leave the batteries connected like that for 20 to 30 minutes. Now if you check the battery using a multimeter you will notice that the voltage has increased. Now once you are done you should reassemble the battery pack and use the charger. The battery must now be charging properly. So, next time if you see that your battery is not charging properly, you can jump start the battery using another good battery. 

To keep the Ryobi batteries in good condition you must maintain the batteries properly. You should charge the battery at the correct room temperature. The battery must be stored in a place that is not too hot or too cold. You must check the batteries regularly to see if anything is wrong. Keeping the batteries idle for a long time may result in damage. Even if you are no longer using the battery you should charge the battery every four to six weeks. This way the battery will be in its best condition. Make sure you don’t overcharge the battery. Always remove it from the charger once you have charged the battery. The Ryobi batteries can get hot quickly. So, it is recommended that before you charge the battery, put it in a cool place. That way the battery won’t become too hot after charging. So, the risk of the battery getting damaged will be reduced. Any minor problems with the battery can be fixed easily, but for more serious problems you must take it to a repair shop.
