对象存放 和 数组存放

Some people swear by storing their batteries in the refrigerator to extend the lifespan of the battery and keep them fresh (apologies for the obvious food-storage joke). But does it actually help? Is there any legitimate reason for putting your batteries in cold storage?

有些人发誓将电池存放在冰箱中，以延长电池的使用寿命并保持电池新鲜(对明显的食物储存玩笑道歉)。 但这真的有帮助吗？ 是否有正当理由将电池冷藏？

Dear How-To Geek,

亲爱的How-To Geek，

I was looking for a little battery storage box on Amazon today with the goal of keeping my discharged rechargeable batteries in one box and the freshly charged batteries in another. While looking at the battery storage boxes I noticed a bunch of them (like this Dial AA Battery Storage Box) were labeled “Suitable for refrigerator storage”. What the heck? Why would you put your batteries in the refrigerator?  I search online for a definitive answer, but it seems like every other web site contradicts the one before it. What’s the deal? Should I be putting my batteries in the refrigerator or not?

我今天在亚马逊上寻找一个小的电池存放盒，目的是将已放电的可充电电池放在一个盒子中，将新充电的电池放在另一个盒子中。 在查看电池储藏盒时，我注意到其中一堆(如“ AA拨号转盘”电池储藏盒 )标有“适用于冰箱储藏”的标签。 有没有搞错？ 你为什么要把电池放在冰箱里？ 我在网上搜索了一个确定的答案，但似乎其他每个网站都与之前的网站相矛盾。 这是怎么回事？ 我应该将电池放入冰箱吗？

Sincerely,

真诚的

Battery Confused

电池混乱

You certainly have the right to be puzzled by the topic and then confused by the search results you found; there is a ton of misinformation mixed in with outdated information floating around. The five second summary on the subject is that some batteries, in some situations, actually do benefit from refrigeration. But practically speaking, most of the time nobody should be putting their batteries in the fridge. Let’s dig into the subject a little to see when it would be appropriate.

您当然有权对主题感到困惑，然后对发现的搜索结果感到困惑； 大量错误信息与过时的信息混在一起。 关于该主题的五秒钟摘要是，在某些情况下，某些电池确实确实受益于制冷。 但实际上，大多数情况下，没有人应该将电池放在冰箱中。 让我们深入研究该主题，以了解何时合适。

First, let’s look at why people are even putting their batteries in the refrigerator. The underlying principle (which is actually scientifically sound) is that the colder temperature slows the rate of energy discharge. Every battery has a rate of self-discharge, the rate at which it loses a percent of its stored energy while just sitting there doing nothing (e.g. in the package, tossed in the junk drawer, etc.)

首先，让我们看看为什么人们甚至将电池放入冰箱。 基本原理(实际上在科学上是合理的)是较低的温度会降低能量释放的速度。 每个电池都有一个自放电率，即坐在那里什么也不做时(例如，放在包装中，扔进垃圾箱等)时，电池会损失一部分存储的能量。

This self-discharge occurs because of what are known as “side reactions”, chemical reactions that occur within the battery even when there is no load applied to it. There is no way to avoid self-discharge, but improvements in battery design and manufacturing have significantly reduced how much energy is lost during storage. Here’s how much common battery types typically discharge per month at room temperature (around 65F-80F).

这种自放电的发生是由于所谓的“副React”，即即使未施加任何负载，也会在电池内发生化学React。 无法避免自放电，但是电池设计和制造的改进已大大减少了存储过程中损失的能量。 以下是在室温(大约65F-80F)下每个月通常会放电多少种普通电池。

• Alkaline Batteries: These are your most common disposable batteries: the kind you buy, use until they’re discharged, and then dispose of them. They’re quite shelf-stable and typically lose 1% or less of their charge per month.

  碱性电池：这些是您最常见的一次性电池：您购买，使用直至放电后再处理的那种电池。 它们非常稳定，通常每月会损失1％或更少的费用。

• Lithium-ion Batteries: Found in laptops, high-end portable power tools, and mobile electronics, lithium-ion batteries have a discharge rate of around 5% per month.

  锂离子电池：在笔记本电脑，高端便携式电动工具和移动电子产品中都有发现，锂离子电池每月的放电率约为5％。

• Nickel-Cadmium (NiCa) Batteries: Although not widely used today, nickel-cadmium batteries were the first widely adopted rechargeable battery. You can still find them on some portable power tools and in other applications, but few consumers are buying them today for light home rechargeable use. The discharge rate on nickel-cadmium batteries is typically around 10% per month.

  镍镉(NiCa)电池：镍镉电池虽然今天没有被广泛使用， 但却是第一个被广泛采用的可充电电池。 您仍然可以在某些便携式电动工具和其他应用程序中找到它们，但如今很少有消费者购买它们以用于轻便的家用可充电设备。 镍镉电池的放电率通常约为每月10％。

• Nickel Metal Hydride (NiHM) Batteries: Nickel metal hydride batteries largely replaced NiCa batteries for consumer use (especially in the small battery market). Early NiHM batteries had a rather high rate of discharge and could lose up to 30% of their charge per month. Low self-discharge (LSD) NiHM batteries were introduced in 2005 and have a discharge rate around 1.25% per month, which is on par with the low discharge rate of disposable alkaline batteries.

  镍氢(NiHM)电池：镍氢电池在很大程度上取代了供消费者使用的NiCa电池(尤其是在小型电池市场中)。 早期的NiHM电池放电率很高，每月可能会损失多达30％的电量。 低自放电(LSD)NiHM电池于2005年推出，每月放电率约为1.25％，与一次性碱性电池的低放电率相当。

Looking at the discharge rates, it makes sense that in some applications some people would want to put batteries in the fridge. If you were a photographer that needed to store a bunch of early generation NiHM batteries for your flashes, for example, it might have made sense to charge them all at once, put them in the fridge, and then throw them in your gear bag the morning of a big event.

从放电率来看，在某些应用中有些人可能希望将电池放入冰箱。 例如，如果您是一位摄影师，需要为闪光灯存储一堆早期的NiHM电池，则可以一次全部充电，将它们放入冰箱，然后将其放入装备包中，这可能是有意义的。大事件的早晨。

Practically speaking, however, there’s next to no reason to put your batteries in the fridge. Whatever gains you might get in shelf-life using the technique would be offset by potential problems. Micro condensation on and inside the battery can damage it and cause corrosion. Extremely low temperatures (such as a very chilly portion of the fridge or placing them in a freezer as some people erroneously advise) can further damage the batteries. Even if you don’t outright damage the battery, you have to wait for the battery to warm up to use it and keep it from gathering condensation if the room is humid.

但是，实际上，几乎没有理由将电池放在冰箱中。 使用该技术可以使您在保质期内获得任何收益，但都会被潜在的问题所抵消。 电池内部和内部的微小凝露会损坏电池并引起腐蚀。 极低的温度(例如，冰箱中很冷的部分或某些人错误地建议将其放在冰柜中)会进一步损坏电池。 即使您没有彻底损坏电池，也必须等待电池变热才能使用它，并在房间潮湿的情况下防止电池凝结。

In essence, you’re risking ruining your batteries to squeeze a few months of storage out of them and, further, the batteries that benefit most from cold storage are rechargeable and could have just been recharged prior to your intended use. To seal our stance on leaving your batteries at room temperature, the manufacturers themselves officially recommend against it. So, buy your battery storage box, but keep it in a cool, dry, and non-refrigerated location.

从本质上讲，您冒着毁坏电池的危险，将电池从中抽出几个月，此外，从冷藏中受益最大的电池是可充电的，可能在您打算使用之前就已经充电了。 为了密封我们的立场，将电池置于室温下，制造商自己正式建议 不要这样做。 因此，请购买电池储藏盒，但要将其保存在阴凉，干燥且非冷藏的地方。
