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:

| 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 |
