6 FAQs about [How to wake up a sleeping lithium ion battery]
How to wake up a sleeping LiFePO4 battery?
There are several ways to wake up a sleeping LiFePO4 battery. From connecting the battery to a charge from a solar panel, to warming up the battery and even connecting your sleeping battery in parallel to another LiFePO4 battery. The steps below are the safer and easier way to wake a sleeping lithium battery.
Can you wake up a lithium ion battery?
As long as you still have a bit of juice in the battery you should be able to wake it up. The easiest way (by far) to wake your lithium-ion battery up after it has gone into sleep mode is to use a battery charger that includes a BOOST or WAKE UP feature built right in.
Why do lithium ion batteries enter sleep mode?
Lithium-ion batteries enter sleep mode due to self-discharge or over-discharge. Self-discharge occurs when the battery is left unused for an extended period, causing the battery voltage to drop below a certain threshold. Over-discharge, on the other hand, occurs when the battery is discharged beyond its recommended voltage range.
Can a sleeping Li-ion battery be boosted?
The voltage of a sleeping Li-ion is not visible, thus boosting must be done with caution. Li-ion batteries are more delicate than other systems, and reversing the voltage might result in irreparable damage. Charging and discharging:
Can a lithium battery charger wake a sleeping battery?
Most lithium battery chargers can’t wake a sleeping lithium battery. But some smart lithium chargers, such as the Victron Blue Smart IP65 Charger, will ‘force feed’ a sleeping battery a low current until it wakes up. Once it’s awake, they’ll resume normal charging. 2. Lithium Battery Jump Starter
How to charge a sleeping LiFePO4 battery?
It’s a catch 22. The solution is the method described above: jump the sleeping LiFePO4 battery with another battery or power source of identical nominal voltage until it wakes up. At that point, it will start reading a voltage in its normal voltage range, and your lithium battery charger should start charging it like normal.
