8/3/2023 0 Comments Energizer ultimate lithium aa![]() Typically, higher temperatures increase the chemical reactions and storage capacity of a battery.Īccording to Scientific reports, a 36℉ increase in temperatures can cause a 20% increase in a lithium battery's maximum storage capacity. On the contrary, warmer temperatures boost the performance of LiFeS2 batteries in high-tech devices. How? LiFeS2 batteries have a larger surface area and use a non-aqueous electrolyte, which increases the conductivity of the batteries as temperatures drop. They perform optimally between -40℃ and 60℃ (-104℉ and 140℉) and hold power when stored at the same temperatures.Īlthough chemical reactions for most batteries are slower at temperatures below room temperature, you can expect LiFeS2 batteries to deliver optimally at temperatures as low as -40℃. You can depend on your Energizer Ultimate Lithium batteries in all seasons, thanks to their low-temperature sensitivity. Superior Performance in Extreme Temperatures You can count on these AA and AAA batteries to hold at least 95% of their initial power up to 20 years in storage. The Energizer Ultimate Lithium AA batteries are the world's longest-lasting batteries as they can hold a charge for up to 6 times more than other leading brands. ![]() Energizer AA lithium batteries are different they allow you to discharge up to 0.5 volts when used in high-drain devices. Most batteries have a voltage cutoff of 0.8 volts per battery to make the most use of the available battery capacity. Let’s say it runs for 36 hours then, the battery is said to have a capacity of (100 mAh x 36 hours) = 3600 mAh if it drains at that rate to the 0.8 cut-off voltage. However, it’s less sensitive to the drain rate and voltage cut.įor instance, the capacity of an AA Energizer Ultimate Lithium battery being discharged at 100 mAh to a 0.8-volt cut-off can be calculated by multiplying the drain rate by the hours needed to reach the cut-off voltage. The capacity of LiFeS2 batteries varies due to the jelly construction that features multiple layers of active materials. The cut-off voltage is the point at which a battery is fully discharged, going beyond this point may cause harm. The drain rate refers to how fast or slowly a battery discharges. These LiFeS2 stand out for a variety of reasons.īattery capacity refers to the duration that a battery can provide service at a specific drain rate and cut-off voltage. The Superiority of the Energizer Ultimate Lithium Battery A design like this provides about 20 times the more interfacial surface area and 30% less battery weight when compared to standard alkaline batteries.Īn Energizer Ultimate Lithium battery cell weighs about 15 grams and has a total volume of 8 cubic centimeters. The LiFeS2 battery features a spiral construction or jelly roll shape that results from rolling the two thin and long electrodes. The chemical reaction between lithium and iron disulphide produces a lithium iron disulphide (LiFeS2) battery with a minimum voltage of 1.5 volts.īecause lithium reacts with water, the electrodes are dipped in a non-aqueous electrolyte made from lithium salt dissolved in an organic solvent. Lithium is a premium material due to its high conductivity and low electrode potential, producing high energy density batteries. Lithium batteries are superior in chemistry as they comprise less than one gram of super active and light lithium (Li) material for the anode and iron disulphide (FeS2) material for the cathode. The batteries differ from regularly used alkaline batteries in chemistry and construction. Energizer Lithium batteries are long-lasting batteries that provide serious power for all your critical devices.
