You don’t really realize how many things around the house require batteries until the batteries run out and you have to replace them. That’s when something so seemingly simple can turn into the biggest annoyance. You either have to make a special trip to the store, remember to get batteries while you’re out, or “borrow” a fresher set from a device you’re not using at the time. Instead of all that, try rechargeable batteries. You purchase them once and can reuse them over and over, which translates into a whole lotta bang for your buck. Some sets can recharge up to 500 times, are guaranteed for 10 years in storage, and often include a recharge station. Before you buy your first set of rechargeable batteries, here are a few other notes you’ll want to keep in mind.

Some devices around the house seem to just eat batteries alive, while others seem to keep the same battery for as long as you can remember. For those items that go through batteries like they’re going out of style, using rechargeable batteries that can be refreshed up to 500 times is going to bring a whole new level of convenience into your life. When the batteries die, simply charge the set for the specified amount of time, put them back in your device, and you’re ready to roll.

Do you want to switch over to rechargeable batteries but still have the old style you’re waiting to die? No problem. Rechargeable batteries can sit in storage for up to 10 years without suffering any damage, so take your time using up what you’ve already bought before switching over. This also means that when you find a deal on rechargeable batteries, you can stock up with no worry that they’ll expire.

To make things even easier on yourself, find rechargeable batteries that come with a charger, but not just any charger. A smart charger can automatically stop charging when the battery reserve is full, so you aren’t wasting energy and money. Bonus points if the charger has a light that lets you know when the batteries are ready for use.
