When you use a digital camera, radio-controlled gadget or other device, you need a battery that will power it for a long time. Luckily, there are several options on the market that will do just that.
These batteries are based on the lithium iron disulphide (LiFeS2) chemistry, which produces more power for longer than normal alkaline. They also last longer in high-drain devices, such as flashlights and cameras.

1. Energizer Ultimate Lithium AA Batteries
Energizer Ultimate Lithium AA Batteries deliver long-lasting power for a variety of high-tech devices. They’re perfect for digital cameras, GPS units, wireless controllers and Lithium Ion Battery Supplier. They’re lightweight and leak-proof, performing in extreme temperatures from -40 to 140 degrees F, so you can be confident your essential devices will work at their peak performance.
They also offer 20 years of storage, letting you keep a ready supply on hand for future emergencies. These batteries are rated to be the world’s longest lasting lithium AA battery and provide up to 8 times longer life than standard alkaline batteries, making them ideal for most preps that take the smaller AA size.
They’re also among the best batteries for flashlights, as they last a long time under normal use conditions and have a great shelf life. Their cost is higher than others on this list, but we think they’re worth it for the quality and longevity they offer. Plus, they’re a good choice for smoke detectors and other always-on preps that don’t use a lot of power, saving you money through less frequent battery changes.
2. Amazon Basics Alkaline AA Batteries
If you’re looking for a cheap battery to stock up on, then the Amazon Basics alkaline batteries are an excellent choice. They can last for up to 10 years when they aren’t in use, so they make a great alternative to expensive lithium batteries.
They also offer a wide range of sizes, so they should fit most devices you have around the house. They aren’t ideal for high-draw appliances, though, so they might not be the best choice if you have some more heavy duty items.
However, they are a good option for general use in small devices such as wireless keyboards and mouse. They’re also compatible with most remote controls and television controllers.
3. Panasonic Zinc Carbon AA Batteries
Panasonic Zinc Carbon AA Batteries are a popular choice for powering a wide range of appliances. They are cheap, reliable and offer a long shelf life, making them a great backup power source for your home.
They are ideal for devices that consume little energy, such as clocks, remote controls and torches. They are also an environmentally friendly power source, as they can be safely disposed of in regular household waste.
These batteries are available in a variety of chemistries, including nickel-cadmium (NiCd), nickel-metal hydride (NiMH) and lithium-ion. NiCd and NiMH have a nominal voltage of 1.2 V, while lithium-ion offers a higher capacity at 3.6 to 3.7 volts.
Zinc carbon batteries are dry cell primary cells, with a zinc anode and a manganese dioxide cathode. They produce a voltage of about 1.5 volts, which is sufficient for most applications. However, they cannot be used at a high current for long periods of time. Lithium-ion batteries are better suited to these purposes, as they can sustain high loads and have a longer service life than zinc carbon batteries.
4. PKCell Xtra Heavy Duty AA Batteries
PKCell Xtra Heavy Duty AA Batteries use a clever and unusual carbon zinc chemistry to produce a low power output, but one that will last for a long time. As a result, they are ideal for devices that demand modest power but want to last as long as possible without sacrificing the user experience.
The batteries themselves are a bit clunky and the price is steep, but they do offer some of the most impressive power to weight ratios we have ever seen, and the battery pack comes with a micro USB charging cable that is surprisingly compatible with most modern smartphones. They also have a hefty 600 mAh capacity, making them one of the best rechargeable batteries we’ve tested. Lastly, they are one of the longest lasting we’ve tested. The most important part is that they are a great choice for your most essential gadgets. It’s a shame they aren’t available in more sizes, but that will probably only change in the future.
