February 18 is National Battery Day. While this day may not be a federal holiday, it’s a date that tech enthusiasts and scientists may like to observe. While the origins of this holiday are a bit unclear, February 18 does happen to be the birthday of Alessandro Volta, the Italian physicist and inventor who is credited with the idea of the electric battery. Over the years, battery companies have taken advantage of this holiday to offer giveaways and sales on their products.

National Battery Day also acts as a safety reminder to make a yearly check of all the batteries in your devices. One of the Rayovac pages for National Battery Day reminds consumers that they should never mix used and new batteries in a device. This could cause the batteries to leak, which would likely damage your device. Batteries Plus offers additional battery safety advice on one of their National Battery Day pages. The company reminds people to avoid storing batteries at very high or very cold temperatures, and suggests that you should never attempt to charge a laptop, cell phone, or car battery that is colder than 60 degrees Fahrenheit. National Battery Day is also a good day to check your car’s battery for corroded terminals. In honor of National Battery Day, we’ve rounded up five great deals on batteries for all types of toys, devices, and machinery. Read on to see some great deals. After all, you can never have too many batteries. Please note supplies may be limited and some items are subject to unexpected changes in price.

AA batteries are used to power all kinds of things in your house, from your remote control to small kitchen appliances. They are often used to power kid’s toys, as well as office items like wireless keyboards. Because they are used in such a wide variety of devices, AA batteries are worth stocking up on. Amazon is selling a 40-pack of Duracell AA batteries for just $19.99, which is a huge discount off the normal retail price.

Looking for a charger that’s beefy and rugged? This portable battery’s best feature is its 2.1A smart USB port. This smart charger can identify a specific device, and offer you maximum charging efficiency and speed for that item. This massive battery will charge an iPhone 5s at least six times, a Galaxy S5 more than four times, or an iPad Air once.

The case on this charger is built tough, and you can charge two devices at once. Another nice feature is the LCD screen. Unlike some other chargers, which use a series of LED lights to give you a rough estimate of how much juice is left, this display is much more precise. If you hate having to guess at how much of a charge you have left, this external battery is a great buy. This pack has a life of at least 500 charging cycles, though it is rated to last beyond that minimum.

At a certain point, you realize it’s a lot cheaper to buy rechargeable batteries than to keep on buying “normal” batteries. Not only is it cheaper, but it’s better for the environment. We like this charging bay from EBL because it charges AA and AAA batteries simultaneously. The charger automatically switches to trickle charge when charging is nearly complete, which ensures that maximum amount of charge for the battery.

If you’re still using an iPhone 5s, one of the best battery cases you can buy is the Mophie Space Pack. The Mophie Space Pack made Digital Trends’ list of the top 40 iPhone 5s cases. Not only does the Mophie Space Pack provide extended battery life, but it provides extended storage as well. The Space Pack case is normally available for $149.95 for the 16GB variety, but there is also a 32GB case available for an additional $30. The Space Pack effectively doubles the battery life of an iPhone 5s with a 1700mAh battery, and maintains a fairly slim profile to boot.

There is not an iPhone 6 version of the Space Pack case available at this time. One iPhone 6-compatible battery case you may want to consider is the Alpatronix BX140, which has a 3100mAh battery.

Price: $131.21 (13 percent off)
