why does higher current mean lower discharge capacity

Yes, twice the current discharge means half the time to battery depletion in the ideal case. The capacity (at least to a first order) is the same in both cases. A battery''s

A practical understanding of lead acid batteries

This is a charger that charges the battery with a maximum current of 0.8A. As it can take a very long time to charge a larger capacity battery with a tricklecharger, you need a regular charger, that can supply a decent

6 FAQs about [Battery discharge current will become smaller]

How does current affect battery discharge time?

The current flowing out of the battery during the discharging process determines how quickly the battery will be depleted. A higher current means a faster discharge time, while a lower current means a slower discharge time.

How does discharging a lithium-ion battery affect its lifespan?

When discharging a lithium-ion battery, the discharging current, or the amount of electrical energy drawn from the battery, is an important factor to consider. Higher discharging current results in a faster discharge time, but it can also cause battery damage and shorten its lifespan.

What happens if a battery is discharged constant power?

Keep the discharge power unchanged, because the voltage of the battery continues to drop during the discharge process, so the current in the constant power discharge continues to rise. Due to the constant power discharge, the time coordinate axis is easily converted into the energy (the product of power and time) coordinate axis.

Why does the internal resistance of a battery increase with discharge current?

The internal resistance of the battery increases with the increase of the discharge current of the battery, which is mainly because the large discharge current increases the polarization trend of the battery, and the larger the discharge current, the more obvious the polarization trend, as shown in Figure 2.

What affects the change of battery discharge voltage?

The change of the battery discharge voltage is related to the discharge system, that is, the change of the discharge curve is also affected by the discharge system, including: discharge current, discharge temperature, discharge termination voltage; intermittent or continuous discharge.

What happens if a battery discharge rate is high?

The discharge capacity at 4C was 71.59% lower than the standard capacity provided by the battery manufacturer. When the discharge rate was high, the ohmic internal resistance, polarization internal resistance and total internal resistance all decreased with the increase of the discharge rate.
