Customers are always happier when they get their phone back and the battery isn't dead or has a good charge so they can test it or are able to use it immediately after the repair. The Kaisi will activate these batteries when you push the Battery Activation button which can bring back to life what was thought to be a dead or bad battery.Īnother feature is the ability to simply charge batteries so if you have an iPhone that has a low battery you can charge the battery while repairing the phone. Most phones won't recognize or charge a battery once the protection circuit has been triggered so the battery needs to be activated or boosted using a slow charge to raise the voltage above 3 volts in this example. This means that if the protection circuit is triggered at 3 volts then if the battery sits for too long or is drained below 3 volts the battery voltage at the connector will read zero volts. Lithium Ion batteries in cell phones have protection circuits that are triggered when the battery goes below a preset voltage which is usually between 2.2 to 3 volts depending on the battery manufacturer.
The first thing we'll address is it's ability to activate dormant or sleeping batteries.
