Many Bluetooth headsets use the rechargeable lithium-ion type of battery. It is actually the most popular type of rechargeable battery, not only among Bluetooth headsets, but also for other electronic devices such as laptops and cell phones.
One of the main reasons that lithium-ion (lithium-ion) batteries are the favorite battery type for many Bluetooth headsets is that these types of batteries have a higher energy storage capacity. What this means is that lithium-ion batteries have a higher energy-to-material ratio than other types, such as nickel metal hydride (NiMH) or nickel-cadmium (NiCd) batteries. For the same amount of nickel or nickel-cadmium, the lithium-ion battery can hold more energy.
The second main reason is that lithium batteries do not degrade their performance even if you recharge them while not completely depleting the stored energy. Unlike other batteries, the lithium-ion battery does not show the so-called memory effect. It also has greater resistance to severe temperatures and does not self-discharge as fast as the other types when in storage.
As much as everyone would like lithium-ion batteries to last forever, the fact is that they have a limited life. When properly used and cared for, they can power your Bluetooth headphones for up to approximately three years. The key here is knowing how to get the lithium-ion battery packs in your Bluetooth headphones to their optimal lifespan. Here are some tips.
Do not completely drain your battery of energy. In reality, lithium-ion batteries do not need to be completely empty before they need to be recharged. In fact, you will shorten the life of your batteries by frequently emptying them before recharging. However, it is also healthy to fully discharge your lithium-ion battery from time to time, for example, after every 25 or 30 partial recharge cycles.
Never subject your lithium battery to high temperatures when recharging it. Not only will heat be a safety risk, but it will also shorten the battery life and power capacity.
If you intend to leave your Bluetooth headphones unused for some time, you must ensure that the batteries are at least half charged. Also, never leave the battery inside your Bluetooth headphones if you are not going to use the devices for a long period of time. If you do, the active material can leak out and corrode and damage your unit. Store batteries in a cool place. Even the refrigerator will do, but never the freezer.
These practical tips are easy to remember. By keeping them in mind and following them, you can be sure that the lithium-ion battery for your Bluetooth headphones will last up to its maximum service life.
