How Many Amps Does A 9V Lithium Ion Battery Have? Understanding Current
If a smoke detector draws 0.5 amps, a 600 mAh 9V lithium-ion battery can power it for about 1.2 hours. However, if a device requires 2 amps, the same battery may only last for about 0.3 hours, illustrating the trade-off between current demand and battery life. Factors that influence the output include temperature, battery age, and discharge rate.

Discover how many amperes a 9V battery delivers, its capacity, discharge rate, and much more. Get all the details on current, types, lifespan, and alternatives.
9V Battery Current Range
For standard 9V batteries, this information is not always available, but these batteries are not designed to deliver high load. This datasheet shows a discharge rate of 150mA continuous, at this rate the battery would be done in about 8 hours. Given this is a high end battery, I would not get over 100mA discharge rate for a standard 9V battery.

For example, if the battery started out a 4.0 V, then decreased over 1.9 hours to 2.7 V when you considered it empty, the capacity is 1.9 hours times the discharge current. If
What is the max current output of a standard 9 volt battery?
No one seems to be talking about peak or max current values because nobody chooses a 9v battery to push a ton of current. It looks like when you get to even the 500ma mark, the internal resistance gets in the way so badly that your battery is basically failing. That way you maintain a steady low current draw, which the 9v is comfortable
What is the max current I could draw from a 9V battery?
As to maximum current, it all depends on chemistry, how long you want to draw current, how much money you have to spend, etc. As a simple rule, I would suggest you use AH/20 as a useful yardstick.

6 FAQs about [9V battery discharge current]
How long does a 9v battery take to charge?
For standard 9V batteries, this information is not always available, but these batteries are not designed to deliver high load. This datasheet shows a discharge rate of 150mA continuous, at this rate the battery would be done in about 8 hours. Given this is a high end battery, I would not get over 100mA discharge rate for a standard 9V battery.
Can a 9v battery output 0.6V?
After all, it is a 9v battery and output at 0.6v is likely to be irrelevant for any application that specifies a 9v battery. Also the actual durations over which each voltage can be exceeded with a few current levels that would be typical for applications that specify 9v batteries.R
How much current can a 9v battery deliver?
The range of current that can be delivered by a 9-V battery depends on its chemistry and quality of manufacturing (and design target). For example, a freshly made "Zeus 9V alkaline battery" can deliver 2.5 A of current (9.5V with 3.9 Ω load for 0.3s): With voltage drop of just 0.1 V, this make the battery ESR of 0.1/2.5 = 0.04 Ω.
How do you know if a 9v battery is 2500 mAh?
Some datasheet will give you a value in Amp, other will give you a value in C, like "2.5C" which refers to the battery Amp Capacity in A or mA. If the battery is 2500mAh, 2C would mean 5Amp, 0.5C would mean 1.25Amp. For standard 9V batteries, this information is not always available, but these batteries are not designed to deliver high load.
How much power can a 9v battery draw?
I can draw about 5ma out of my wimpy 9v battery and I think your super-duper 9v battery can do no better. If you are talking about a PP3 style battery, the alkaline version has a capacity of around 600mAH. So for any sensible lifespan you are looking at a useful maximum of around 30mA.
Can a 9 volt battery be discharged at 100 Ma?
Here are the discharge curves at 100 mA. I have thrown in a Panasonic Super Heavy Duty carbon-zinc battery, it obviously was never meant to be discharged at 100 mA. The first thing to realize is that 9 volt batteries were never designed to operate at 500 mA. This test was for a special project.
