Tip: This article's comparative evaluation is: simple comparison evaluation, no detailed professional comparison, only subjective comparison of individual use experience.
leadIn the undergraduate period, in a boring engineering mathematics class, the teacher's boring explanations and tedious course content made the landlord drowsy and unable to stand up. After listening to a small section, I picked up the bag and left afterwards. I went straight to the subway station and went to a photographic equipment store that I had long been looking for. I bought the Metz 52AF-1, a flash memo that I had done for a long time. Cool. Why buy this flash? Because it is not an easy task to achieve a high-speed synchronization between the flash and the Pentax cameras, the Metz 52AF-1 is one of the solutions. Here we don't think about the flash. We need to talk about it later.
ExteriorSpeaking of a small episode above, is to lead today's protagonist: rechargeable battery. After buying the flash, since the flash needs to release high power instantaneously, the battery used must also be unusual. Simple to do some homework, try to buy first to say, then place a white love wife, 1900mAh Eneloop. Since then into the pit of the Eneloop battery.
Since then, I have bought 8 black love wives and I am curious to buy 8 white green standard AmazonBasics rechargeable batteries for comparison (the legendary white green leaf label is Eneloop OEM). Black love wife and white AmazonBasics are shown below.
Please don't mind the large blue color in the picture, because the battery storage box you bought is blue, and the picture is cold. I hope to give you a bit of coolness in the hot summer days. In fact, the battery has a lot of students, and I mainly talk about their differences and use of feelings.
ComparedFirst of all, their respective parameters are:
Eneloop black models: nominal minimum capacity of 2450mAh, total about 500 charge cycles. Low self-discharge.
Eneloop White: The nominal minimum capacity is 1900mAh, total about 2100 charge cycles. Low self-discharge.
AmazonBasics white model: The nominal minimum capacity is 1900mAh, total about 1000 charge cycles. Low self-discharge.
From the nominal data above, the two white models have the same capacity, but AmazonBasics has a shorter life. The details of the three models are similar. As shown below:
On the use of feelings: black love wife is no doubt, the life of the boss, the capacity of 2450 is not blowing, and the gap between the two white is very obvious. These batteries are mainly used for the Xbox handle in daily life. There are slight differences in the use of the two whites. The white love wife feels a little better than the white Amazon Basics, and the charge time of the former is slightly longer after use, but the difference is not large.
Therefore, from such handles, if you are concerned about life, then buy high-capacity models, the price is higher. If you think that white models are enough, then white models, as to love your wife or AmazonBasics, the latter is definitely more cost-effective, less 1000 times the nominal cycle life can also be ignored, to be a simple calculation to know that 1000 times The cycle can also be used for many years. If you like to love your wife, what else would you say, buy it?
However, the use of another aspect, such as the most typical one, is used on the camera's external flash.
Many people say that the camera flash has a high power consumption, and it is definitely more suitable for a black love wife. actually not. The instantaneous power of the flash is very high, reaching tens of thousands of watts, but it only completes the flash action within a few ten-thousandths of a second. Therefore, it is important that the battery's ability to instantaneously output high energy and return speed is very important. This requires low internal resistance of the battery. This is the strength of the white love wife. There will be obvious feelings in actual use. Under the external working status, if you take pictures quickly and continuously, the black love wife and AmazonBasics obviously can't keep up with the speed of the flash because of the large internal resistance. When the flash is continuous, the flash does not appear. The probability of a bit is much higher. There is no detailed data statistics here, just use subjective feelings and welcome exchanges.
Purchase suggestionHere's a summary of the purchase recommendations: If there is no requirement on the speed of the internal resistance, hope to buy long-term high-capacity models, black love wife or black AmazonBasics (although I did not buy this); if there is not much demand for battery life, Think 1900 capacity is enough, then buy white AmazonBasics, the most cost-effective, and white love wife gap, but very small. If you just like to love your wife, buy it. As for the cycle life, I don’t think it’s too tangled up and I don’t need to charge every day. 500 cycles are enough for many years.
If you need fast internal resistance, such as a flash, then love your wife. If you don't have enough capacity, buy a few more.
About chargerThese batteries are best not to use silly enough, you can consider multi-functional charger, such as the following Nitecore D4 charger, playing flashlight, all know this brand is still very famous.
The charger can charge a variety of battery types independently, with screen display charge status, charge time, voltage and current battery type and many other parameters.
Since four channels are independent, so it does this:
Still like this:
It can be perfectly charged, regardless of its model, battery type or charging position, it can be mixed and independently charged. The red battery is 18650 and is used in the flashlight below:
The charger also supports trickle charging, but it does not support such functions as discharging and measuring power, and I have no need for such use. If you have a variety of models of rechargeable batteries, especially those similar to the 18650, this type of charger is very practical. The price is not high, one hundred yuan will be able to get.
This time, we will come here and we will meet again next time.
Inductors serve as indispensable components in electronic circuits, effectively managing current flow and filtering out unwanted frequencies.
