BU-808a: How to Awaken a Sleeping Li-ion

Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. Slipping into sleep mode can happen when storing a Li-ion pack in a discharged state for any length of time as self-discharge would gradually deplete the remaining charge.

Should you fully discharge a Li-Ion battery on first use?

So to prevent this, the charging circuitry will intentionally brick the battery (prevent you from ever recharging it) if it determines the charge level is too low. If you discharge the battery and leave it sitting, the gradual self-discharge can drop the battery''s charge level past this threshold, resulting in a permanently bricked battery.

6 FAQs about [Is it bad to fully discharge a lithium ion battery]

What happens if a lithium ion battery is fully discharged?

When a lithium-ion battery is completely discharged, it can no longer provide power to a device. A fully discharged battery will have a voltage of 0 volts and will not be able to hold a charge. If you try to charge a fully discharged battery, it will not be able to accept the charge and will eventually die. How to Discharge a 12V Battery?

Should a lithium ion battery be fully discharged before recharging?

Full eruptions should be avoided because they put additional strain on the battery. Studies have shown that a lithium-ion battery regularly discharged to 50% before recharging will have a longer lifespan and may retain up to 1,500-2,500 cycles, compared to just 500-1,000 processes if regularly fully discharged.

Is it dangerous to charge a deeply discharged lithium battery?

Yes, it is dangerous to attempt to charge a deeply discharged Lithium battery. Most Lithium charger ICs measure each cell's voltage when charging begins and if the voltage is below a minimum of 2.5V to 3.0V it attempts a charge at a very low current . If the voltage does not rise then the charger IC stops charging and alerts an alarm.

Can a Li-ion battery be discharged deeply?

No, it is not OK to have a Li-Ion deeply discharged at all. Here is why: When discharged below its safe low voltage (exact number different between manufacturers) some of the copper in the anode copper current collector (a part of the battery) can dissolve into the electrolyte.

What should you know when working with lithium ion batteries?

One of the most important things to know when working with lithium ion batteries is how to properly discharge them. If you don’t discharge the battery correctly, it can cause serious damage to the battery and even lead to a fire. Here’s how to properly discharge a lithium-ion battery:

Are lithium ion batteries dangerous?

Rapid discharge can indeed be harmful if it leads to excessive heat buildup. However, lithium-ion batteries are designed to handle certain levels of immediate dismissal without damage. For instance, electric vehicles, which use large lithium-ion battery packs, can accelerate, requiring high discharge rates.
