Do lithium batteries last longer-introduction and usage?

Lithium batteries are the most used batteries nowadays, and it is important to know their longevity. Lithium batteries can last for 15-20 years, but if well cared for, they can last for 25 years. The longevity of lithium batteries also depends on their use. 

If their use is rough, it won't last longer than 5 years. BYD Auto claims that its lithium battery can last for about 20 years. They supply batteries to Tesla, and Tesla also claims that their EV battery can last for 20-25 years. Lithium batteries can last for 3,000 cycles if properly taken care of.

Do lithium batteries last longer than alkaline batteries?

Lithium batteries outplay alkaline batteries in all sorts. 

How long does an alkaline battery last?

Alkaline batteries have a shelf life of about 5-8 years. This means without any use they can last for this much time. Without any use, they self-discharge, and after a given number of years, they will stop working. Alkaline batteries, even when used for about 5 years. 

Alkaline batteries are single-use batteries that can be used once and then thrown away. Alkaline batteries are heavy and can leak as well, making them dangerous for this reason, many people opt for lithium batteries.

Why do lithium batteries last longer than alkaline batteries?

The reason why alkaline batteries last less than lithium is due to lithium is light which makes lithium battery to store more energy than any other battery. The lightness of lithium also gives lithium batteries high energy density.

Both batteries are single-use batteries, but lithium batteries last longer because, with use, alkaline batteries lose their strength and become weaker and weaker. While on the other side, lithium, even with rough use lithium batteries, does not lose strength and will last longer than alkaline batteries.

How many mAh do alkaline batteries have?

A standard alkaline AA battery has about 2,850 mAh of capacity. Standard lithium AA battery has a maximum capacity of 3,000 mAh. In comparison to alkaline batteries, they are outlasted by the barest of margins. The mAh doesn't prove the longevity of the battery, but just its capacity of it.

Do lithium batteries last longer in cold weather?

Lithium batteries have this specialty that they can work in extreme temperatures. If the weather is cold or hot, they can work fine. Lead acid batteries don't work properly in extreme temperatures. Using the lead acid battery in cold conditions can degrade and harm the battery life. 

For this reason, lithium batteries have been developed, which work perfectly fine without harming the battery life.

Lithium Batteries in Cold Weather

Lithium batteries are best in cold weather situations. They can work properly till -4 Fahrenheit. Temperature falling below -4F will cause the battery to decrease power capabilities and performance. Living in cold weather regions, lithium battery is the clear winner compared to other batteries. Lead acid alkaline batteries show a huge decline in performance in cold temperatures.

Why lithium batteries are best for cold temperatures?

Lithium batteries don't show a decline in performance regarding temperature. They work the same at extreme temperatures. Lead acid batteries, if pulled in cold temperature, decline more and becomes weaker. 

While lithium batteries, on the other hand, warm up and lowers batteries resistance and increase the voltage, which makes the lithium batteries not produce a decline in performance.

Lithium Batteries vs. Alkaline Batteries in Cold Temperatures

Lithium batteries have proved that its better than every other battery in cold temperatures. When compared to alkaline batteries, lithium batteries are far better. Alkaline batteries working principle is based on chemical reactions, and in cold temperatures, there is a reduction in chemical reactions. 

Alkaline batteries are water-based electrolytes, and cold weather causes the battery to have a decline in the transfer of electrical power. Alkaline batteries also leak out in cold temperatures.

How long do lithium batteries will work if not used?

Non-rechargeable lithium batteries can last for about 10-12 years if they are not being used. At the same time, rechargeable lithium batteries can last for about 2-3 years. Lithium batteries degrade with time. In comparison to other batteries, lithium batteries last the longest when they aren't being used. Alkaline batteries have a shelf life of 5 years.

Self-discharge Effect on Lithium Batteries

Self-discharge is a term that is used in non-rechargeable batteries, which means batteries deplete their charge with time. It can also cause a difference in the internal chemistry of the battery. The rate of lithium batteries in self-discharge is less than all the other batteries.

 Lithium battery self-discharge rate is 1.5-2%, while the self-discharge rate of lead acid batteries is 5%. Self-discharge can affect the longevity of the battery directly. Batteries with high self-discharge rates last lower than batteries with low self-discharge. For this reason, lithium batteries last longer than lead-acid batteries.

Temperature Effect on the Longevity of Lithium Batteries

Temperature can also affect battery longevity. Increasing temperature can decrease the longevity of the battery if it's lithium or alkaline. Lithium batteries last longer than alkaline when they aren't being used and when the temperature is extreme. 

Non-rechargeable lithium batteries last the longest when they are stored at room temperature. Lithium battery's longevity changes with temperature. If we compare the longevity of lithium batteries at room temperature with longevity at cold temperature, the longevity at room temperature will be the greatest.

Depends on the Care of the Battery

If a lithium battery is taken care of, even if it isn't used, it can have great longevity. If the battery is placed in a dry, properly ventilated place that has room temperature, then the batteries will have great longevity. If the battery is placed in a moist and poorly ventilated place with having hot temperature, the battery will only last for a few months.

Conclusion

Lithium batteries are far better than every battery out there so far. Lithium batteries can work perfectly fine at extreme temperatures, and they can last the longest as well. Cold weather also cannot decrease the performance of lithium batteries.
