Dependable Energy: Li-Ion Rechargeable Batteries

Look around and youll see items that you depend on daily. Whether youre commuting, camping, or jogging, more than likely, you use devices that require batteries. Rechargeable batteries come in 1.2V and other voltages, and they have distinct advantages over batteries you use and toss.

What Advantages Do Lithium Ion Batteries Have?

A rechargeable lithium-ion battery has a higher energy density so it stays charged longer. As lithium ions move back and forth, electrons are created to power devices. Lithium-ion batteries last longer because they self-discharge slower than non-rechargeable batteries. Moreover, since the battery doesnt need discharging, you can place it in a device and forget it. You wont need to buy batteries as often as Li-ion batteries last up to 3 years when used regularly. These time-saving lithium batteries recharge to 100 percent capacity in approximately 30 minutes. 

What Are Common Uses for Li-Ion Batteries?

  • Flashlights: People keep flashlights on a bedroom side table, a vehicle glove compartment, or in a shop. When powered by a rechargeable battery, you can count on the flashlight when tent camping or looking for items in an attic. The 1.2V batteries power small stick-up LED lights you place in a cabinet or closet.
  • Everyday Items: Theres nothing worse than having a TV remote control with dead batteries. In addition to remote controls, use a rechargeable battery to power your camera flash or keep lithium-ion batteries on hand for your childrens toys. Li-ion batteries are suitable for handheld game consoles and electronic cigarettes when youre weaning yourself off tobacco.
  • Surveillance and Alarm Systems: Surveillance equipment is sometimes placed in remote areas when electricity is unavailable. These systems powered by lithium-ion batteries help you monitor tools and equipment at job sites and other locations.

How Do You Extend the Life of Rechargeable Batteries?

Lithium batteries transported in a pocket full of coins could short-circuit. Instead, carry them in a bag that has zippered dividers. Every time you replace batteries, clean the contacts using a cloth with a rough texture. This optimizes the connection between the device and the battery. Furthermore, store your batteries at room temperature since excessive heat shortens their life. You should not fully discharge a lithium-ion battery below 2.5 volts per cell. Doing so causes the built-in safety circuitry to trip, indicating the battery is dead. Most manufacturers recommend that you dont store fully-charged batteries. If you store lithium batteries in the refrigerator, discharging them to 40 percent capacity reduces oxidation, thereby extending their lifespan.
