Why does the battery drain so much when I leave it in the camera?

Introduction Why does the battery drain so much when I leave it in the camera? This is called stopping energy consumption. Typically, cameras are turned off to consume power. A good camera draws a few microamps when it's off, so you can plug in enough.

Why does the battery drain so much when I leave it in the camera?

This is called stopping to consume energy. Typically, cameras are turned off to consume power.

A good camera draws a few microamps when turned off. If you feed it enough, it will take 2-3 years to run out of power.

But a bad camera draws a few milliamps when turned off, 1 milliamp per hour, 24 milliamps per day, and a lithium battery of about 1,000 milliamps will run out of power eventually. about a month. Put it back in the camera, it will be too discharged. It is difficult to activate lithium batteries when they are over-discharged. Some people say that if the camera is not used for a long time, the battery cannot be charged. If it is a lithium battery camera, unfortunately you will need to purchase a new battery. If it is nickel metal hydride, it may equalmust be activated.

Some cameras turn off and consume power for several hours. So it's not that the shutdown consumes power, but that the circuit is faulty and needs to be repaired. A 1000 mAh battery discharges in 2 hours and the current is around 500 mAh per hour. The operating current is therefore higher than turning on the screen for navigation, which means it does not turn off and therefore is not broken. ?

As for the amount of power consumed when the camera is off, that actually has nothing to do with the SLR or the card itself. This has something to do with the price of card machines which now cost €300. 400 yuan. Is the price cheap? Naturally, the components are not up to date, including the precision specifications of the components, so it's no wonder it's good.

Compared with 600MA 14500 lithium iron phosphate battery and r batteryechargeable AA nickel-metal hydride 2300MA, which one has the longest endurance when used in digital cameras?

The battery given to you when purchasing the camera is for testing purposes. This is a disposable battery and cannot be recharged.

If you do not use your camera often, you can purchase alkaline batteries (such as Nanfu brand alkaline batteries). You can take 4 or 50 photos. The cost is slightly higher.

If you use your camera frequently, you should purchase NiMH rechargeable batteries. The national brands Speedmaster and Pivot are both good. Pinsheng 2500mah 4pcs + charger costs around 100-120 yuan. Once 2 batteries are fully charged, you can take over 200 photos.

Canon offers original chargers, which can be purchased in Canon stores. But the price is very high, it is not necessarytry to buy originals. With this type of charger, you also need to remove the battery and install it on the charger to charge it, and it cannot be "charged directly by connecting the camera to power".

In fact, this type of AA battery (AA battery) also has its own advantages: the capacity of this type of lithium battery cannot yet be very large (lithium batteries generally used in cameras have a capacity of around 1000mah). Rechargeable AA nickel-metal hydride batteries can reach 2,500 mAh; Once the lithium battery runs out during shooting, it will be difficult for you to recharge it until you return to your place of residence. be anxious! If you run out of nickel-metal hydride batteries, you can purchase alkaline batteries for emergency use. Alkaline batteries like Nanfu can be easily purchased at the most popular scenic spotsules of China.

Recommend 1000-2000 yuan camera, lithium battery, wide angle, telephoto and macro camera

The number of battery cycles at lithium iron phosphate is more than 2500, and the number of cycles of the nickel-metal hydride battery is more than 2500. About 500 times, and there is memory effect, in terms of service life, lithium iron phosphate is much longer than nickel metal hydride. From the capacity you wrote, 2300 is more than 600, which means a standby time for the two batteries you mentioned, nickel metal hydride is more than. Lithium iron phosphate, charge per day If you discharge it once, the nickel metal hydride battery lasts 500 days, which is 1 year and 135 days. Lithium iron phosphate battery lasts 2500 days, almost 7 years. , the lithium iron phosphate battery should be longer thanthe nickel battery. Hydrogen is expensive, think about it for yourself
