Which Batteries Perform Best?
You probably have AA batteries scattered around your house. You use them for your remote controls, your grandkids’ toys and many other everyday items. Face it, you can’t live without batteries, but somehow we always seem to run out of them.
But before you buy AA batteries, you need to know a few things. First, there are two types of batteries: alkaline and lithium. More to the point, not all batteries are a good value. Does paying more mean you’ll get a better, longer lasting battery?
No, not according to Consumer Reports. They tested 15 brands of AA batteries, including Amazon-branded batteries and Costco’s Kirkland batteries.
The prestigious magazine found that some lower cost batteries are just as good or nearly as good as the most expensive brands. In fact, you’ll be shocked by how you don’t need to break the bank for high-quality batteries that will keep your Christmas presents humming for weeks or months.
Note: Consumer Reports tested batteries in two ways: They used the batteries until they died in toys for one hour a day and in flashlights for four minutes every eight hours.
Alkaline vs. Lithium
First things first. You’ve probably noticed that generally speaking, lithium batteries are expensive.
You might be tempted to buy them, thinking that if they cost more they probably last longer. As it turns out, Consumer Reports suggests using lithium batteries sparingly, like in devices that need a quick burst of power or that you don’t use very often.
Note: You can store lithium batteries for up to 15 years. They don’t need to be stored in the refrigerator and they don’t usually spew liquid like older, carbon-zinc batteries did.
Some alkaline batteries performed as well as lithium batteries in Consumer Reports’ test. These batteries are typically less expensive. You may want to use them in devices you use a lot, like your TV remote control and your computer’s wireless mouse.
So, which brands performed best in Consumer Reports’ tests? Both alkaline and lithium batteries were among the best values.
This might surprise you. The top performers included two brands that might have the perception of being “cheap.”
