Energizer Ultimate Lithium AAA Battery

Energizer's AAA Ultimate Lithium batteries, presented in a 4-pack, epitomize the brand's reputation for cutting-edge power solutions. From the outset, these batteries distinguish themselves with a lightweight feel, attributable to their lithium composition. But it's the longevity and consistent energy output that truly set them apart.For devices that demand a stable power source or are frequently in use, these batteries are a boon. They last considerably longer than standard alkaline batteries, making them ideal for high-drain devices like digital cameras, gaming controllers, and flashlights. Their performance remains uncompromised even in extreme temperatures, a testament to their robust construction.An often-underappreciated advantage of the Ultimate Lithium line is its shelf life. These batteries can be stored for up to 20 years without a significant drop in energy, ensuring they're ready to deliver when needed.The eco-conscious will also appreciate that using long-lasting batteries reduces overall waste. While the initial cost might be slightly higher than traditional batteries, the extended life more than compensates in the long run, both economically and environmentally.In essence, Energizer's AAA Ultimate Lithium batteries are a testament to quality and reliability. For those seeking extended battery life without frequent replacements, this pack is an excellent investment.My TV remote loves them as they last for 12 months without any power drop. Highly recommended.

High quality batteries perfect for radios calculators etc

Bought these to fit my Emergency flashing road flare kit. This kit can be a lifesaver especially if your car breaks down on a so called 'Smart Motorway' where there is no hard shoulder. Grab these flares, switch them on and get as far away from the car as possible.These lithium batteries will stay in these flares for years without losing power or leaking.A bit pricey but for this application, money well spent.

This would be a 5-star product if it weren't so expensive. Unfortunately, Energizer hold the patents for them and take full advantage. The sad part is, they could completely wipe out alkaline cells if they made more and sold them at a lower price.I'll forestall the would-be rant there, though, and tell you about the product. In short: no other non-rechargeable cell can touch these. They are extremely capable. They deliver full capacity at much higher power levels than alkaline cells can, and they withstand extreme temperatures much better as well. They have a very long shelf life, and I've never, ever seen one leak.As an example, I have two of these in an outdoor temperature sensor. They've been exposed to -10°C, +30°C and everything in between for two years. That's already twice the time I was getting from Duracells, and they're still going.If you have expensive equipment that doesn't like rechargeables, especially if it needs high power, or you need good performance in extreme conditions, I advise you to bite the bullet, pay the money and buy these (stock up on deals if you see them). Forget the alkaline cells, they don't even come close for the hard jobs.

Arrived quickly, ideal for intended use.

have a long battery life, costly against other ones but being lithium do thr job on my remote handsets

Tested both pack of cells (20 cells) that I ordered with a digital multimeter.They all read between 1.8 and 1.803V. This is a GOOD sign that the cells are not junk.I’ve had other-branded cells (EBL) that have been 1.7V on arrival.A voltage much lower than 1.8V shows that the cell is either poorly manufactured, older than labelled, damaged, and/or is self-discharging. In other words, junk.Lithium primary cells have a higher energy density and current capacity than alkaline and much higher than your basic Leclanché cell.A good quality lithium primary cell should retain the majority of its capacity for at least 10 years without discharge or leaking.A HUGE advantage of this property is that they are extremely useful when it comes to applications like TV remote controls where the cells go unforgotten for long periods of time.Standard Leclanché and alkaline cells have a nasty habit of spilling their corrosive contents all over the contacts of low current devices long before they are exhausted.By the time your device stops working, the electrolyte from them has often leaked out and eaten the contacts of the device away.This does not happen with Lithium cells, so use these instead.Yes, lithium cells are more expensive, but they excel in high-current applications, as well as very low-current drain ones.They are also much lighter than other cell types.

I will keep coming back for these as I find it so hard to buy these anywhere else. They last so much longer than other batteries especially for security camaras.
