Energizer battery chargers have a big light on top that shows green and red lights flashing in different ways. If you aren’t sure what those flashing lights mean most of the time, don’t worry.
I’ll talk more about the Energizer battery charger today, especially the meaning of the lights on it. These can sometimes signal problems, so it’s important to know about them to avoid any damage.
The Meaning of Different Energizer Battery Charger Lights
- Energizer Charger Displaying Solid Green
When the cells inside an Energizer charger are at 100% of their battery capacity, the light will shine a bright, solid green. There won’t be any changes in the pattern.
That means the solid green light signals that your batteries are done charging. It’s going to keep shining like in the picture below until you take the batteries out of the charger.
- Energizer Charger Displaying Solid Red
Solid red might seem like danger, but don’t worry; it’s not (at least not in this case). This is the light you’ll see most often, as it’s the one that pops up whenever you put batteries inside.
That’s because the solid red light on Energizer chargers signals regular charging. Here’s a picture of what this particular light looks like.
Your batteries inside aren’t at 100% yet, and the light is staying solid red to just let you know they’re powering up. It’s best not to take the batteries out while this light is still there.
- Energizer Charger Blinking Red
This time, red DOES mean there’s a problem. If you ever see your Energizer charger blinking red over and over again, it’s probably a good idea to take all the cells out of it.
That’s because the red flashing light signals a dead battery, or one that’s incompatible with the Energizer charger. Here’s what that’ll look like on the charger when it happens.
Your Energizer charger won’t send any power to the batteries when this particular light is displayed. That’s because the batteries aren’t safe to charge, and you should remove them.
This usually happens when you try to charge cells that are completely dead and can’t hold power anymore, or try to charge two different types of batteries in one go.
Like trying to charge an AA and AAA battery together, for example. That’s not a good idea due to the differences in power requirements, so the charger won’t work to protect from issues.
You’ll stop seeing this light and it’ll shift back to solid red once you put two similar batteries inside, or take out any dead ones.
- One More Thing to Keep In Mind
That’s all the lights there are on an Energizer battery charger! But, while I’m on the subject of potential problems, there is one more I’d like to discuss so newer users know about it.
Energizer chargers have 4 slots for 4 different cells. These slots actually work as a pair. To make it clearer, the two slots on the left are for one set of batteries, and the two slots on the right are for one set.
The two batteries you put on the left side will charge together, and the two batteries you put on the right side will charge together. Check out the image down here so that it’s easier to understand.
As you can see above, when charging two cells, you have to put them in slot 1 and 2 (or 3 and 4). If you put them in slot 1 and 3, or 2 and 4, the charger won’t work because it doesn’t recognize a pair.
