Step 2: Remove the old battery:
First, take the battery out of its position and you will find two cables (red and black cables) connected to the circuit board. (Please remember the connecting points.) Please use the welding tool to fuse these two cables and you can remove the old battery.
(Do you want your own welding tool? We recommend you a BEST US-standard plug with $8.36, SKU: 23001165.Click the link below and get it now.)

Use the welding tool to weld the red cable of the new battery to the point on the MP4 circuit board. Weld the black cable with the same way. And then the indicator of the MP4 is on, which proves the replacement is successful.

Step 4: Cover the housing:
After replacement, put the battery on the previous position and cover the rear cover. Screw on the screws.
