             Cell Phone Battery Quick Charging Activation Plate Board for iPhone 4/5/6 7 8 Plus/X/XR/XS Max/Samsung Circuit Test Repair Tool

Usage: buckle the small board on the mobile phone battery to charge and activate the battery; buckle the small board, the battery light will be on, first adjust the power meter to 3V when charging (if it is directly adjusted to 5V, it will be protected) and then slow Slowly increase the voltage to 5V.

Rice noodle scene: This product uses the original battery contact holder, plug it into the power supply to check the phone startup current, use the current method to judge the phone failure, and buckle it on the phone motherboard for use.

Regarding the problem that the activated small board cannot be charged:

First of all, the voltage of the battery is between 3.7v-4.2v. Generally speaking, if the cell phone shows 50% of the battery, the battery voltage is still (4.2-3.6=0.6 0.6/2=0.3 4.2- 0.3=3.9) At this time, the battery voltage is still around 3.9.

Generally, if the battery needs to be activated, it is not used for a long time, or the voltage is lower than 3.6v, so the common charging tools can not be rushed in. At this time, the activation board is used to activate the battery. When activated, the voltage is generally 3.6v. Customers are usually used to using 4.2v to charge the battery. At this time, if the voltage is too large and cannot be charged, it will cause a short circuit or unchargeable display on the power supply. (Normal At this time, we need to use the constant current mode to charge, but many customers don’t know how to use constant current charging) so when we charge with a regulated power supply, the general voltage only needs to be adjusted to 3.7v to charge, (if not possible Just 3.6v) for a while, and then slowly rise (amplitude: 0.1v) if it still shows that the short circuit cannot be charged, then adjust back to the previous voltage and charge for a while, until it can rise to 4.2v.
