6 FAQs about [Batteries with low current and long discharge]

What is discharge current in a lithium ion battery?

The discharge current is the amount of current drawn from the battery during use, measured in amperes (A). Li-ion cells can handle different discharge rates, but drawing a high current for extended periods can generate heat and reduce the battery’s lifespan.

What happens if a battery is deeply discharged?

“If a battery does become deeply discharged, special care must be taken during the subsequent recharge. With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke.

What is discharge voltage in a Li-ion battery?

The discharge voltage is the voltage level at which the cell operates while providing power. For li-ion cells, the typical voltage range during discharge is from 3.0 to 4.2 volts. It’s crucial to avoid letting the voltage drop below 3.0 volts, as over-discharging can lead to irreversible damage and significantly reduce the battery’s capacity.

How long does a battery last if fully discharged?

If battery if fully discharged, it will reach full charge after 50 hours (2 full days). However, if the battery is just partially discharged, it will reach the “full-charged” state much sooner. Would it get charged to its full capacity, say from 12 V to 12.7 V after a long duration? Would it go permanently bad in the process?

What if a battery charger is low voltage?

With the aid of very low current, an attempt must be made to rebuild the basic voltage so that charging can then resume normally from 3 V,” says Heydecke. Users must therefore ensure that suitable chargers are used and to avoid damaging the devices and batteries.

How long does a lead battery last?

Most lead batteries will be OK at 14.5 V for a few hours (but make sure you read-up for more information on your specific battery type). If you limit the voltage to, let's say, 13.6 V, then the battery may last a long time. Like several years. This is just a quick answer.
