Take away the M18 battery and look at charge meter. There’s a button on the pack you push. It tells you how many bars is remaining, so you quickly know if you should of changed it or not.
Then you hook it up to charge. The process couldn’t be easier. You prepare charger for use. The setup is simple.
Understanding Indicator Lights
I use either my normal Milwaukee M18 charger for this and that’s fine too but the Rapid Charger seem to do a good job as well.
Slide the battery into place on the charger unit. Ensure it’s seated well as you’ll need a good connection for the charging to begin. Once clicked, process starts.
Once you slide the battery onto the charger, the red LED instantly begins blinking to show that the battery is receiving power. You can then just sit back and watch as the light pulses until your pack are full.
It takes about 30 minutes for a small cell like a 2.0 Ah to charge. In terms of charging time, it’s roughly an hour for the 5.0 Ah unit.
Since you would expect bigger packs to require more time to charge, you’d be right. It takes about 90 minutes for the 8.0 Ah high output. That’s not too bad for a pack that big but it’s the slowest.
When it’s done flashing red, you wait until it goes solid green. If the green light is steady then the pack are completely charged. The green light means it is done, and off we go again.
The indicator is checked on the 5.0 Ah pack again. It’s solid green. Yep, it’s finished. It is consistent from model to moddern; you know what to look for.
Also keep an eye out for other lights. Indicators show when a battery has been hot or cold. Particular indicator lights will also shows fault conditions.
It’s nice because then you don’t have to guess at what’s going on; you can see it and fix it before there is problem.
It saves you some time when you know exactly what every light signifies
The system is easy to understand and uses simple colors so you don’t have to worry about being in the wrong color.
Charging is red, done is green. If there’s an issue, it will alert you to that as well.
That’s great for controlling power of your tools.
After checking the button, they put sequence in.
Then comes the introduction to the charger.
You check the indicator on the 5.0 Ah pack again. The solid green confirms it is done. You know exactly what to look for because consistency exist across different models.
Insertion
You watch out for other lights as well. The charger displays alerts for hot or cold batteries, and fault conditions triggers specific indicators. These warnings help you identify issues early, so you do not need to guess what is wrong.
Check the timing on the 8.0 Ah. Check. Green light verified. I am introducing the others. Skip IMG3 since the 2.0 and 5.0 Ah timings were already mentioned above. Seeing the orange light again would not add any new information.
