Therefore, if you connect the AC power cord to the outlet and in case the ring terminals or alligator clips aren’t plugged into the battery, probably the green and red lights will be seen.
I would advise you to rotate the terminal clips or wires, rubbing them on the terminals to ensure they are tightly held in place.

You should also want to ensure that the battery terminals are in good working condition, free from acid accumulation. Try to check if the wires are not correctly fixed and put them in place. It is as simple as that.Īnother reason that you are seeing a flashlight on your battery charger is that the connection between the charger and the battery is very poor. Handling such a situation is simple as you only have to expose the pack to the electricity for some hours before reinstalling the battery for charging. Of course, you will start to see a red light flashing immediately when you insert a battery on your battery pack that has been dormant for a while. The battery pack hasn’t been in service for a long period. You can change such a situation because of its nature, but you can place your battery on a stand that’s either one or two feet above the ground. If you are operating in winter or any cold environment, the battery charger light will blink red. The surrounding is too icy to charge your battery pack. There are several reasons that may force the charge light display differently. The battery charger CHARGE light blinks when charging your battery pack If it’s irritating, you are required to detach at least a single battery to let the light go off. You will continue to see the red light even after unplugging the charger. Detach the battery and give it another try to see whether it picked or responded to charging. I would advise you to leave the batter overnight on the charger while the red light continues to flash. Leaving it on the charging will help strengthen the cells, respond to charging and pick normal operations. You don’t have to worry about this 90-second flashing red light because it simply implies that the voltage of the battery is too low. Therefore in such situations, it’s advisable to allow the chemistry to stay on charging for a few minutes. This issue happens mostly when the battery is over drained, leaving it with no volts. On the other hand, you will start to see a flashing red light at an interval of 90 seconds immediately after connecting the charger. Draining the battery is one way of restoring ‘bad batteries’ and is the simplest way. In such a case, you are supposed to ensure the batteries are completely drained before trying to charge again.

Sometimes the battery might be having a full charge, but still, need charging. So, if you see such an indicator, just know that the battery might be full or bad. It is a clear indication that your chemistry requires a restoration, or else, it can’t be charged.
In case you insert the battery and you see the red light blinks at an interval of 5 seconds, the voltage of the battery is too high. Experts recommend various methods of restoring batteries that won’t be charged using a battery charger. This happens occasionally, whereby the charger displays a flashing red light that indicates bad batteries. Restoring bad batteries is what I can begin by as the meaning of blinking red light in my battery charger. Remove at least one of the batteries and the light will go off.Why am I seeing the flashing red light on my battery charger? The red light remains on when the charger is unplugged. Leave the batteries in the charger, while the light continues to blink red, for about 24 hours. If the light blinks red in about 90 seconds after battery insertion, then the battery voltage is too low. If charging is needed, briefly drain the batteries before trying again. This indicates that the battery already have a full charge. There are several ways to restore batteries that cannot be charged by the charger.If the light blinks red within five seconds after battery insertion, then the battery voltage is too high. Occasionally, the charger might show blinking red right to indicate bad batteries. Rescuing “bad batteries” indicated by a blinking red light. The charger has a built-in converter circuitry that will become warm during rapid charging. It is normal for the charger to become warm while rapid charging. This does not mean the batteries are charged faster than others or overcharged The two batteries will become warmer than the other batteries due to heat generated by a converter circuitry in the charger. It is normal for the two rear batteries to become warmer than the other banks.
