How Long Does One Battery Last?

alkaline battery do last

You are using a computer, and suddenly the wireless mouse won’t move, and you find that the battery in the mouse is dead. When you buy a battery, you must want to know how long the battery can be used in the mouse?

In addition to the mouse, home electronic door locks, smoke alarms, etc., when you change the battery, you must also want to know how long the battery can last? When will it be replaced next time?

This problem is actually very simple. Just test the battery, but usually it takes a certain amount of time to test. As an ordinary user, the test is actually quite difficult, so how can I know how long it can last?

Meanwhile it is typical to hear advertisements that promise batteries are strong enough to keep on working for a long time, well after other batteries have died. Of course, no one is going to say that their brand of battery runs out quickly!

So, Who can you trust? What do you need to know to make an informed decision regarding which flashlight batteries last the longest?

In this article, I will combine the IEC60086-2:2015 formulated by the International Electrotechnical Commission, regarding the time requirements for the application of dry batteries to different electrical appliances, and how long our batteries can actually be used. These data are theories derived under laboratory conditions. Value, but it is of great reference significance for us. We can refer to these data.

I listed several conventional models, such as zinc carbon battery R03/AAA and R6P/AA, as well as alkaline battery LR6/AA, LR14/C, LR20/D, 6LR61/9V, and analyze the data respectively, and then everyone can learn from them Understand how long the battery we bought can be used in the electrical appliance.

1, About R03/AAA:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Portable lighting 5.1Ω 4 min on, 56 min off for 8h/d 0.9 83 min
Toy 5.1Ω 1 h/d 0.8 79 min
Digital audio 50 mA 1 h on,11h off for 24h/d 0.9 7.1 h
Remote control 24 Ω 15 s/min,8h/d 1.0 7 h
Radio 75 Ω 4 h/d 0.9 23 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: R03/AAA in radio, it can last 23hours, if the radio is on for one hour per day, it means it can last 23days.

2, About R6P/AA:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Portable lighting (LED) 3.9 Ω 4 min/h,8h/d 0.9 145 min
Motor/Toy 3.9 Ω 1 h/d discharge 0.8 144 min
CD, digital audio, wireless gaming and accessories 100 mA 1 h/d discharge 0.9 7.7 h
Radio/Clock/Remote control 50mA 1 h/8h, 24h/d discharge 1.0 16.2 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: R6/AA in clock, it can last 16.2 hours, if the clock is on for one hour per day, it means it can last 16days.

3, About LR03/AAA:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Portable lighting 5.1Ω 4 min on, 56 min off for 8h/d 0.9 260 min
Toy 5.1Ω 1h/d 0.8 265 min
Digital audio 50mA 1h on,11h off for 24h/d 0.9 21.5 h
Remote control 24Ω 15s/min,8h/d 1.0 20.5 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: LR03/AAA in remote control, it can last 20.5hours, if the remote control is on for 5mins per day, it means it can last 246days.

4, About LR6/AA:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Digital still camera 1 500 mW  650 mW b 1.05 66 pulses
Portable Lighting (LED) 3.9 Ω 4 min on, 56 min off for 8h/d 0.9 425 min
Motor/Toy 3.9Ω 1h/d 0.8 7.9 h
Toy, non-motorized 250 mA 1h/d 0.9 7.9 h
CD, digital audio, wireless gaming and accessories 100 mA 1h/d 0.9 23.5 h
Radio/Clock/Remote control 50 mA 1h/8h, 24/d 1.0 47 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: LR6/AA in remote control, it can last 47hours, if the remote control is on for 10mins per day, it means it can last 282days.

5, About LR14/C:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Toy 3.9 Ω 1h/d 0.8 22 h
Portable lighting 3.9 Ω 4 min on, 11 min off for 8h/d 0.9 1300 m
Portable stereo Current drain 400 mA 2h/d 0.9 13.5 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: LR14/C in toy, it can last 22hours, if the toy is on for 1h per day, it means it can last 22days.

6, About LR20/D:

Appliance Simulate the resistance, discharge conditions and termination voltage of this appliance when it is working How long it lasts
resistance discharge conditions End voltage
Portable lighting 2.2 Ω 4 min on, 11 min off for 8h/d 0.9 830 m
Toy 2.2 Ω 1h/d 0.8 23 h
Portable stereo Current drain 600 mA 2 h /d 0.9 16.5 h

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: LR20/D in toy, it can last 23hours, if the toy is on for 1h per day, it means it can last 23days.

7, About 6LR61/9V:

1 s on, 3 599 s off for 24 h/d 7.5 23 days

Note: The time on the far right is the time that our MICROPOWER BRAND battery simulates the use of this appliance.

For example: 6LR61/9V in toy, it can last 18hours, if the toy is on for 1h per day, it means it can last 18days.

In this article, I only list a few commonly used battery types. We still use button batteries such as CR2032, CR2016, CR2025. If you don’t understand, please feel free to consult and exchange. I will put all the knowledge I know. introduce to you.
