Can't charge anymore the battery

Hello,

I’ve just bought the Xiaimo QiCycle bike, and I was so happy of my purchase.

I’ve ride it to my work for a few time before winter, and I put it in the garage waiting for better days.

The sun comes finaly earlier, and when i tried to charge the battery, nothing works…


I noticed that once connected to the charger, the green led of the charger did not turn red (charging indicator), while the indicator of the bike tells me that it is completely discharged

This green led stay to green, and do not charge the battery:(

Could you tell me what to do to find out if the problem is with the charger or the battery?

Thanks a lot for your responses !

thanks for your response, but it does not answer to my question...

Could you tell me the right state of the charger led when the charger is connected to AC/DC input, but disconnected from the battery ?

Not connected to the battery, this led should be green, red, or turned off ?

Update (03/07/2019)

I managed to recharge part of the battery (60%) by doing the following:

1. connect the charger to the battery

2. connect the charger to the power supply

3. wait for the sound click of the charger

4. unplug the charger from the power supply

5. Repeat steps 2, 3, 4 several times until the red LED starts to appear.

Maybe it will work for you Andrew

Can't seem to get that to work for me. I also bought a new charger and it also doesn't charge the battery :(

When you are doing steps above, are you pulling out the cable from the wall and plugging it back in each time?

I’ve just recieved my new charger sent for free by Geekbuying.

And…

My two batteries are now fully charged !!!! YES !

So this is the answer i was looking for :

In good working use, you have to first plug the charger to the battery, and then plug the charger to the power supply.

  1. Then the led lights to green.
  2. After a few seconds, the charger detects that the battery is not fully charged, and the light turns red (permanent, not blinking).
  3. When the battery is fully charged, the led turns green permanent.

My broken charger make a little sound, like an electrical relay which close or can’t close at the moment it should turn to red (step 2). But the charger is not demountable, so i can’t do anything…

A new charger is not so expensive and you could find one on Ali express

The 220v wire has a type of plug very common in CEE on charger side (like a radio), so even if you find only a UK version of the charger, you’ll easily find a french version of the plug

In fact, Carmello Castellano in his comment on 7 march had given the answer… Thank you !

It should be green until it is plugged into the battery and then it should turn red.

thanks a lot for your response !!!

So if the charger don't turn to red blinking, can i wrap up that the charger is out of order, or rather the battery iteself ?

による

I have the same problem. I've ordered a new battery AND charger so ill be able to let you know which had a problem, at least for me.

による

hello, i'm so sorry for you... Where did you find a new battery and charger ? Could you tell us where you have ordered your bike ? Did the after sale service make you a proposition ?

For me it is GeekBuying, and they tell me to resend the entire bike... :(

They finally offered me a new battery to 118 €, I think I will accepted in comparison with the shipping cost to return the entire bike ... I called a Xiaomi's shop in Paris, and they have confirmed that no spare parts were available in France, and that they were not even sure that this bike would be one day distributed in France ...

If you receive your new battery and charger, i'm still interested to know where the problem came from

I bought from catch.com.au and they also want me to return the whole bike :( so I ended up buying new battery and charger from AliExpress. The battery has not arrived yet. But the charger did, and it still does not charge the battery. So I can confirm it is the battery itself that is faulty. (at least for me)

When it is charging properly, the light will just turn red (it will not blink).
