If your household goes through a lot of AA or AAA batteries, you may not realize how quickly the cost can add up. Perhaps it’s time to consider switching to rechargeable batteries. While the startup cost may seem a little overwhelming, the rechargeables will more than pay for themselves over time.
I compared the current prices of disposable and rechargeable batteries as well as their lifespans to see exactly how much you can save by making the switch. Electric Coffee Mill

Rechargeable batteries have increased in both popularity and quality over time. Now, it’s common to see rechargeable batteries guaranteeing a life of up to 10 years after purchase (if they’re used and charged correctly). While disposable batteries have much shorter lifespans while in use, their low per-battery cost can make them hard to pass up. For that reason, I wanted to see which batteries will help you save the most money over time.
Of course, the environmental implications are something else to consider when deciding whether you want to use rechargeable or disposable batteries. Rechargeable batteries are ultimately better for the environment but only if used for their entire lifespans.
Whether you’re considering making the switch to rechargeable batteries to save money or to help the environment, you’ll ultimately achieve your goal by investing in a quality setup and using the rechargeables for as long as possible.
Rechargeable batteries are going to be the most cost-effective over time — but not right off the bat. You are going to spend more on rechargeable batteries than you would spend on regular batteries during the first year. Rechargeables cost more per battery: Expect to pay more than $3 per battery for a long-lasting, quality brand. Plus, the charging station is going to be an additional cost. Still, you’d be surprised at how much you can save over time by making the initial investment.
When it comes to finding an exact savings figure, that’s tough, because many factors come into play: whether you buy cheap or brand-name batteries, where you buy them, how many you use at a time and how often you replace or charge them. For that reason, what you spend and what you’ll save will vary. But generally speaking, you can expect to see rechargeable batteries pay for themselves within two to three years.
In my apartment, we have approximately 12 batteries in use at a time between game console controllers, TV remotes and wall clocks. I would estimate that we replace approximately two to four of those batteries each month. Of course, if you have kids with toys and electronics or a hobby like photography, you’re probably using many more batteries at a time.
For the sake of the price comparison, let’s assume a household replaces 6 batteries each month, or 72 batteries annually. Here’s how much that household will spend on batteries each year:
Amazon is one of the best places to buy batteries with low to average prices, so I looked at the current prices of disposable and rechargeable AA batteries there to get an idea of how much they cost.
If you use store-brand batteries, AmazonBasics will run you $0.25-$0.75 per AA battery. If you prefer brand-name batteries, I found AA Energizer batteries for as low as $0.60 each at the time of writing (January 2024). At these prices, 72 new disposable batteries each year would cost around $18-$54.
When it comes to rechargeable batteries, you’ll see a higher cost during the first year. Each year afterward, you’ll have no additional cost beyond the pennies that charging adds to your electric bill.
At Amazon, I found the highly recommended Eneloop rechargeable batteries. In January 2024, a charging station with four rechargeable Eneloop batteries was $22.86. Additional 4-packs of the batteries still cost $14.97, and the product page claims the batteries will maintain up to 70% charge after 10 years of storage. So if you want to begin with a charging station and eight rechargeable batteries, you’re looking at an initial startup cost of around $37.83.
Of course, rechargeable batteries and charging stations vary greatly in quality and price. You can find chargers from as low as $10 to as high as $40 on Amazon, so taking the time to research and find a happy medium between price and quality is important. You’re making an investment with rechargeable batteries, so you want to make sure they last as long as possible.
If you’re wondering whether or not it’s worth it for you personally to invest in rechargeable batteries, the short answer is most likely “yes.” Rechargeable batteries are almost always going to be cheaper over time. Even if you replace as few as four batteries each month, you’re still looking at a savings of $22-$142 over the course of five years.
If you have kids who use batteries in their toys or if you have a battery-powered camera you use daily, know that the initial cost for rechargeable batteries will be significantly higher, but your savings over time will be even greater. Let’s say you do replace 10 batteries every month (120 every year). If you buy an Eneloop charger with four rechargeable batteries plus an extra 12-pack, you’ll spend $60.25 the first year, but you’ll save $89.75-$389.75 over five years.
Of course, you don’t have to use rechargeable batteries in all of your battery-powered electronics. If you have batteries in a wall clock or TV remote that you only have to replace once every year or two, it may be cheaper to stick to the $0.25-$0.75 per battery cost as opposed to investing in rechargeable batteries. Instead, you could save the rechargeable batteries for those devices that go through batteries like crazy: game console controllers, kids’ toys, cameras, etc.
Ultimately, rechargeable batteries are going to cost more initially, but the investment will be worth it. In fact, depending on the number of batteries you use, you’ll start seeing savings within 2-3 years of making the switch. Over five years, you’ll have saved a minimum of $64 if you replace four batteries each month. Of course, more frequent battery users will see much bigger savings of $200+ in the same time period.
If you’re ready to move away from disposable batteries, make the switch to rechargeable batteries as smooth as possible by following these tips:
Lastly, keep in mind that you don’t have to use rechargeable batteries in all of your devices in order to save money and be environmentally conscious. If you only have one or two devices that use a lot of battery power, switching those to rechargeable batteries will still make a big difference over time.
