Maximum current draw from 12v sealed lead acid battery?

According to the data sheet, that battery can withstand quite high discharge currents. The Terminal Voltage (V) and Discharge Time curves go up to 3C, which for your battery is 24A*. But you may be very disappointed with how long the battery lasts. Even at 8A, the battery will be flat after half an hour.

Solved The charge and discharge current of a battery is

The charge and discharge current of a battery is measured in C-rate. It is defined as the current divided by the theoretical current under which the battery would deliver its nominal rated capacity (Ah or mAh) in one hour. For example, a battery rated at 1000 mAh provides 1000 mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C provides 500mA for two

What''s the C rating for NiMH batteries? [duplicate]

The "C" rating specifies the maximum safe continuous discharge rate of a pack. If you see 10C on your battery, it means it can be discharged at 10 times that pack''s capacity. This applies to all batteries. There is no difference between Li-ion and NiMH (or any other chemistry, for that matter). If you are not seeing the capacity or "C" factor

A timer should be the least - additionally looking at the current (it reduces notably when near full) or the temperature (it rises when near full, but maybe hard to detect at this little current) do work. Charging with the mentioned 8.4 V and 1/10C is said to take 12-15 h. If you choose the lower current, prolong the timer accordingly (~ 20 h).

6 FAQs about [7 2 Battery discharge current]

What is a 20 hour battery discharge rate?

This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C. 0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity.

Can a battery be fully discharged?

In many types of batteries, the battery cannot be fully discharged without causing serious, and often irreparable, damage to the battery. Manufacturers usually specify the depth of discharge (DOD) of a battery, which determines the fraction of power that can be withdrawn from it.

How long does a battery take to charge/discharge?

In your question, the capacity of the battery is 2.4 Ah, hence, C=2.4 (unitless). The vast majority of the batteries in the market will safely charge/discharge at a rate of less than 1C Amperes. In an ideal world (without losses), this would translate into a 1 hour charge/discharge process.

What is a good battery discharge rate?

Battery manufacturers rate capacity of their batteries at very low rates of discharge, as they last longer and get higher readings that way. This is known as the "hour" rate, for example 100Ahrs at 10 hours. If not specified, manufacturers commonly rate batteries at the 20-hour discharge rate or 0.05C.

How do you calculate battery charge and discharge rate?

Formula: Battery charge and discharge rate in amps = Battery capacity (Ah) × C-rate let's say you have a 100ah lead-acid battery. 100Ah lead-acid battery has a recommended charge and discharge rate of 5 amps let's say you have a 100ah lithium battery. 100Ah lithium-ion battery has a recommended charge and discharge rate of 50 amps

What does 0.05c mean in a battery?

0.05C is the so-called C-rate, used to measure charge and discharge current. A discharge of 1C draws a current equal to the rated capacity. For example, a battery rated at 1000mAh provides 1000mA for one hour if discharged at 1C rate. The same battery discharged at 0.5C provides 500mA for two hours.
