Saving Energy: Should I Switch to Rechargeable Batteries?

Making the switch to rechargeable batteries may not seem rational at first. The costs are higher than the cheap alkaline batteries that you can pick up for a few dollars at many stores. You have to buy a battery charger as well, which makes the initial costs even higher. Whether the investment is worth it to charge batteries in digital cameras, flashlights, children’s toys, remote controls and other devices is a legitimate issue that needs to be addressed.

Rechargeable Batteries Vs. Alkaline

The problem with alkaline batteries is that you can only get one use out of them. You can’t recharge them and get up to 1,000 uses like rechargeable batteries. Once alkaline batteries run their course, you have to throw them out. When you repeat the cycle of using and tossing them out, over and over again, you waste a lot of money. It’s not like you’re going to go without batteries. Most people use batteries for something, and paying for them is a recurring expense. That’s why it’s better to stop using alkaline batteries in most cases.

There are a few instances though, where alkaline batteries are still superior to rechargeable batteries. For example, you would be safer to use one if your smoke alarm requires a 9-volt battery. An alkaline 9-volt battery in a smoke detector will last a year or so, but rechargeable batteries may not.

Hybrid Batteries Vs. Rechargeable Batteries

Hybrid batteries tend to have a higher capacity for storing energy than regular rechargeable batteries. It’s a better choice for many electronics, like digital cameras. Two popular rechargeable batteries that some people like to use in digital cameras are Nickel-Metal Hydride (Ni-MH) and Low Self Discharge (LSD) rechargeable batteries. However, those are not the best products. The hybrid Ni-MH batteries are a better buy.

Hybrid Ni-MH batteries will hold their charge for several months longer than regular Ni-MH rechargeable batteries. You also don’t have to charge most hybrid batteries initially like many rechargeable batteries. They come already charged and ready to use like regular alkaline batteries. Not only is this convenient, but it’s great for saving energy, because you don’t have to plug in a charger before you have to use it the first time.

When you compare all of your options for batteries—alkaline, rechargeable and hybrid—the best bang for your buck in many cases is the hybrid. Rechargeable batteries are still fine to use if you can’t afford hybrids initially, and it’s a better option than alkaline batteries. Make a list of electronics and appliances you need the batteries for, the size required and read reviews from people who have actually used the brand and size you’re considering. Don’t simply rely on manufacturer guarantees.
