How Long Can A Lithium-Ion Battery Last Without Charging?

A Lithium-Ion Battery

It’s not a weird thing to be interested in the length of time a lithium-ion battery will keep running without charge. The non-aqueous electrolyte cells provide power to everyday devices including smartphones, electric vehicles and bicycles.

Under normal conditions the lithium-ion battery can last between 8 and 10 hours, several days or even months, depending upon the capacity of battery size, capacity the battery’s size, its charge level, usage and the environment.

In this article I’ll explain the length of time lithium-ion batteries are expected to endure under various conditions and the elements that determine the length of time they can hold in charge, and the ways to extend the life of your battery.

If the lithium-ion battery has been stored for an extended period without being used the battery could keep its charge for two years or longer. It also depends on the condition of the battery prior to it and following storage.

When the battery has been operating or running a device and left to drain without recharge the battery, it can last only a few hours or even days, depending on the type of battery and the device it’s charging.

When the battery has been a regularly used battery and goes through regular recharge cycles, it can last 3 to 5 years or longer. This is the recommended (default) life span of an lithium-ion battery.

Chemical composition and use

Different lithium-ion battery types have a different chemical composition or chemistry. For instance the lithium-ion cobalt dioxide battery found in smartphones shouldn’t be expected to last as long as those of nickel aluminum cobalt battery in Tesla.

This is due to their chemical composition varies greatly and are designed to suit different tasks. Chemistry is no more crucial than this when it comes to lithium batteries.

When the battery’s capacity as well as load are not the same, battery is unlikely to provide power to your device, nor last as long without charging.

Environment temperature

To allow a lithium-ion battery be optimal performance, it must be operating at the ideal temperature between 20degC to 60degC. If temperatures are outside of this range the battery is likely to evaporate faster.

So, it’s possible to conclude that lithium-ion batteries aren’t able to perform under extreme temperatures or cold because they need to be more efficient in order to keep their charge.

How to Maintain Lithium-Ion Batteries

According to the majority of manufacturers the best lifespan for the lithium-ion battery is three to five years, or minimum 2,000-3,000 charge cycles.
