iPhone battery activator with LCD

Use this unit to test / fast charge, and re-activate iPhone batteries that have gone dead due to very low charge (below safety limit)
Works with iPhone 4, 4s, 5, 5s, 5c, 6, 6 plus batteries, Uses USB or DC Bench Suppy for power.
Connect the battery, note when the battery voltage is lower than 2.5V, digital display will not be displayed due to lack of power supply. 2.5V or higher will then give the normal display.
The voltage display to adjust the sound output voltage (service power supply), the higher the voltage, the greater the current, when the table on the right shows battery voltage is lower than or equal to 3V, please repair the power supply output voltage regulation for the 3.5V
The following trickle charge mode with charge one to two minutes, after turning on the power cord, the right table displays the current charge voltage.
If the battery voltage of 3.6V above the display, you can use directly above 4V charge, will repair the power supply voltage increase, left digital table shows the current charge current digital table on the right shows the current charge voltage.
For a quick charge, please note that at the same time to increase the voltage of the left current display, the maximum should not exceed 2A (2000MA), otherwise it will be automatically protected.

Instructions for use:
In order to better protect the battery and battery protection board, the product design limiting 2A, when (the current exceeds 2A) operation errors, such as accidentally access high voltage, fast charge to activate the test fixture of high current loads Protection play a role, it will automatically disconnect the power supply, thus avoiding damage to the battery (battery protection board burn damage batteries)
After a user finds an error and disconnect the power supply, only one to two minutes of cooling time, speed sufficient to activate the test fixture to resume normal operation.
When you need to leave for a long time, please adjust the charging voltage of 4.6V or less, the battery is fully charged, fast charge and activation test fixture will stop output charge current to prevent overcharging the battery charge up.
