Hi @winterchew520,
Here’s a video that shows how to open the speaker so that access to the battery is possible. I suggest that you use a broader tool such as a paint scraper (old credit card?) rather than a screwdriver or other more pointed tools to pry off the cover as shown in the video, so as to lessen the cosmetic damage.
Here’s an image taken from the video that shows the battery. To make it easier, unplug the speaker connection from the motherboard and then undo the screws holding down the motherboard.
I can’t make it out from the video, but the battery information should be printed on the battery giving the dimensions of the battery, the capacity in mAH and the voltage and sometimes the actual part number.
Searching online for Huawei CM51 battery gives no results. You may have better luck by searching for the part number if there is one
If you can’t find an exact replacement battery by using the part number (if it is there), look for an equivalent battery by searching for (insert dimension “number”) (insert voltage value) (insert mAH value) LiPo battery. If there are none for the exact dimensions etc search for a similar but slightly smaller size (especially the depth, as it has to fit) but ensure that the voltage is the same value and hopefully that the mAH is the same or better.
e.g. if battery values are 305050 3.8V 700mAH and there are none available, look for a 254040 3.8V 700mAH and check results.
I do not know what the dimensions and the voltage values of the battery are in the speaker, although I have found out that the battery capacity is 700mAH The above is just an example of what to try when searching for a replacement
With the dimensions, usually it is shown as a 6 digit number. The convention is that the 1st 2 digits of the number is the height (or depth) in mm with a decimal point (which is not shown), the next 2 digits is the length in mm and the last two digits is the width in mm e.g. 254040 = 2.5mm H x 40mm L x 40mm W

I also have problem with my speaker CM-51. I just let it connected to the laptop thru Bluetooth. When i came back the speaker is already off and not charging and not turning on even if i already let it charged for couple of hours.

Do you solve the problem of CM51? I also have the same problem with my speaker after 2 minutes the red light will disappear.

This is a battery problem or the connector that fits into the speaker from the charger may not be making proper contact. I am trying to find a source to purchase the battery but cannot find one. Does anyone know.
