Batteries

Cordless tools 提供前所未有的便利和多功能性, but this is only possible thanks to the batteries powering them. All users should be familiar with the features and distinctions between different types of batteries. In fact, choosing a battery should be treated much like buying any other tool. 有几种主要的电池类型需要考虑, along with several metrics by which to evaluate them and help you select the right power source for the job.

需要了解的电池术语

安培小时(Ah)
通常缩写为“啊”, an ampere hour refers to the total charge a battery can deliver in one hour. The Ah rating lets you know how long the battery will last per charge. 例如,你可能会看到一个标有3的电池.0Ah rating. 当在连续绘制1的工具中使用时.0 amperes of current, the battery should last around three hours on a full charge. 只需将Ah值除以电流:3.0 / 1.0.
In general, you should match the Ah rating of your battery to the size of the project. For instance, a 1-3Ah battery is best used for small projects. Batteries with a higher charge capacity, such as 8-9Ah, are more appropriate for larger tasks.

Voltage (V)
Voltage determines the amount of power the battery can provide. 电压越高,电池就越强大. More powerful tools require batteries with higher voltages. You can find batteries in a range of voltages based on your needs: 4V batteries may be sufficient for light repair work with a small cordless screwdriver, 12V or 18V batteries for every day huosehold needs while cutting through thick lumber may require a chainsaw that uses a 60V battery.

电池类型

锂离子电池(锂)
Lithium-ion (often shortened to “li-ion”) batteries hold multiple advantages over NiCd and NiMH. They have the largest capacity of the three main battery types, usually exceeding 3.0Ah. They’re also much smaller and lighter than other batteries, 这样它们就不会给电动工具或其他设备带来重量. 锂离子电池没有记忆效应, so you can freely recharge them as needed without worrying about eroding the capacity. 不过,也有一些缺点需要记住. Li-ion batteries have the shortest cycle life at under 500 charges. 它们也是最贵的, so a lithium-ion battery may not be the right choice if you’re on a strict budget.

镍镉研究所
Nickel-cadmium batteries use nickel oxide hydroxide and metallic cadmium as electrodes. The main advantage of NiCd batteries is that they generally have the longest cycle life at approximately 1,000 charges. 但除了延长寿命, there are several downsides that make NiCd batteries less appealing. They have a comparatively low capacity (usually ranging from 1.2Ah to 2.而且容易受到记忆效应的影响. The memory effect occurs when a battery’s charging capacity diminishes over time because it is repeatedly recharged without being allowed to completely drain. As for more practical concerns, NiCd batteries are typically heavier and susceptible to overheating. They’re also harmful to the environment and must be disposed of properly.

镍氢(NiMH)
镍氢电池提供约2.2Ah to 3.0Ah capacity, around two to three times more than NiCd batteries. 它们对环境也更安全. 寿命约为600次, 镍氢电池的寿命没有镍镉电池长, but they should still provide lots of use if well-maintained. NiMH batteries are a good choice if you want solid performance but aren’t inclined to pay more for lithium-ion batteries. However, it should be noted that like NiCd batteries, NiMH are also susceptible to the memory effect.
