I bought a set of 4 lightly used 6aH makita batteries from ebay. Right of the bat, one of the batteries looked different from the others. I used it in a grinder for the first time and died doing some heavy cutting and I could not revive it.

After taking it apart, I knew for sure it was fake. It had knock off cells for 2500maH in a 6aH case! This is what to look out for.

What I noticed on the counterfeit:

1. Dimensions are slightly larger than a true makita

2. The BMS plug is orange instead of yellow

3. It did have the tamper plug with t10 security bolts

4. The letters on the side were all white with no silver

5. It had a red sticker under the tab, but looks different than an original

6. The Press tab doesnt have the indents like an original

7. Sticker on the back doesn't have the airplane in the corner

8. Sticker text is "LITHIUMION" instead of "LITHIUM ION"

9. Fonts are slightly wider

10. Lighter in weight than a true battery

11. You can see through the holes of the battery and see the cheap bms and it green in color. On a true makita battery, I think its white and you can see the waterproofing silicone they use.

There could be more, that I am missing.

For those wondering, it was 20k OTD.
