Another person mentioned that the charger would turn and off, especially if you jiggle the battery. The problem is that the connection fingers are a bit crusty and it wasn't working well, I also had the same problem.Here is the fix: I found that a bit of DeoxIT cleaned out the crud on the connection. Just get a small bottle of DeoxIT and dip the brush with the DeoxIT on to the connector, then put the battery in the charger and remove the battery and put it back into the charger - do this several times (10 times?)It should have a good connection now.My guess is that some the shipping was very slow over the ocean - causing some of the salty air to get into some packages. Other than that, it works fine for me.Here is the link to DeoxIT:https://www.amazon.com/D100L-16BX-DeoxIT-D100L-Mini-Brush-Applicator/dp/B07F8ZX2GD/ref=sr_1_4?crid=3DGJTOWER2VFD&keywords=DeoxIT&qid=1707178445&sprefix=deoxit%2Caps%2C158&sr=8-4

When I received the charger, the charging lights were flickering. I should've returned it at that point but it still charged the battery. After using it about 20 times it stopped working. It won’t charge my battery anymore.
