Many Bluetooth headphones use the lithium-ion type of rechargeable battery. It is actually the most popular type of rechargeable battery not just among Bluetooth headsets but also for other electronic devices such as laptops and cell phones.
One main reason that Li-ion (lithium-ion) batteries are the favorite battery type of a lot of Bluetooth headphones is that these kinds of batteries have a bigger energy storage capacity. What this means is that Li-ion batteries have a greater energy-to-material ratio than the other kinds, 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 power.
The second main reason is that Li-on batteries do not degrade in performance even if you repower them while they are not completely depleted of stored power. Unlike other batteries, the Li-ion battery does not show the so-called memory effect. It also has stronger resistance to severe temperatures and does not self-discharge as fast as the other types when it is in storage.
Much as everyone would like Li-ion batteries to be eternal, the fact is that they have a limited life. When used appropriately and cared for, they can actually provide your Bluetooth headsets with power up to about three years. The key here is in knowing how to make your Bluetooth earphones' Li-ion battery packs reach their optimal life span. Here are a few tips.
Do not completely empty your battery of power. Li-ion batteries actually do not need to be fully empty before you need to recharge them. As a matter of fact, you will decrease the life span of your batteries if you frequently let them go empty first before recharging them. However, it is also healthy to completely discharge your Li-ion battery from time to time, say, after every 25 or 30 partial recharge cycles.
Never subject your Li-on battery to high temperature when you recharge them. Not only will the heat be a safety risk but will also shorten your battery's life and energy capacity.
If you are intending to leave your Bluetooth headsets unused for some time, you should make sure that the batteries are at least half-charged. Also, never leave the battery inside your Bluetooth earphones if you won't be using the devices for a long period. If you do, the active material may leak out and corrode and damage your unit. Store the batteries in a cool place. Even the refrigerator will do, but never the freezer.
These practical tips are easy to remember. If you keep them in mind and follow them, you can be sure that your Li-ion battery for your Bluetooth headphones will last up to its maximum lifespan.
