The Energizer® Ultimate Lithium™ batteries are not only the #1 longest-lasting AA batteries…they are complete with leak resistance and performance in extreme temperatures (-40ºF to 140ºF or -40ºC to 60ºC).

That said, here's what we want you to take away: The Energizer Ultimate Lithium is an amazing product. If you need a battery that you don't want to replace often, this is the thing. But while not having to change your batteries in your wireless system for a day on set is nice, the PHC doesn't justify it for us.

In addition, the ultimate has a longer shelf life than the advanced (15 years vs 10 years) and, compared to the Energizer MAX, lasts 8x longer in a digital camera, whereas the advanced is said to last 4x longer. All info from the mfr, not from my own experience.

To sum it all up, the bare minimum that most manufacturers expect from their batteries is around 3 years or 1,000 charging cycles. With that said - we say “put your warranty where your mouth is.” Bosch, DeWalt, Metabo HPT, Makita, Milwaukee Tool, EGO, and Ridgid all warranty their Lithium-ion batteries for 2–3 years.

Safe, Stable Chemistry One of the most important advantages LiFePO4 has over other battery types is safety. LiFePO4 is the safest lithium battery type. It's the safest of any type, actually. Overall, LifePO4 batteries have the safest lithium chemistry.

In the last week, lithium prices have been widely discussed in the auto industry, and beyond, because the cost of metal necessary to make those batteries has been skyrocketing. According to Bloomberg, the cost of metal grew by 280% last year. In the first quarter, the prices of many metals more than doubled.

These batteries are known for their high energy density, long cycle life, and reliable performance. With their ability to store substantial amounts of energy, 200Ah batteries are suitable for powering various home appliances and meeting the energy demands of residential setups.

As of the end of the first quarter, global lithium-ion battery production capacity stands at 2.8 TWh. S&P Global predicts that this capacity will grow more than 2-fold by 2030, reaching 6.5 TWh. This planned capacity growth will be enough to cover demand.

Energizer claims that their lithium coin cell batteries have up to 10 years of shelf life when properly stored. As far as service life this will depend greatly on the application. A CR2025 battery in a car key fob may last up to 3-4 years before needing replacement as the use of the battery is very intermittent.

Generally, EV car batteries last from 10 to 20 years. Certain factors like heat, cold, or swift charging times can negatively affect that and reduce performance. Manufacturers have already included protective measures like thermal management systems and charging restrictions.
