How to make your Lithium-ion batteries last for years

lithium ionThe lithium-ion (Li-ion) batteries used in most of today’s tablets, smartphones, and portable PCs require very different care and feeding than with the nickel-cadmium (Ni-Cd) and nickel-metal-hydride (Ni-MH) batteries used in earlier devices.

Keep your lithium batteries cool

I was surprised to learn that heat is the number-one enemy of Li-ion batteries. Heat issues can be caused by usage factors such as the speed and duration of battery charging and discharging.

Unplug the charger to save the battery

Overcharging — leaving a battery connected to a too-high voltage source for too long — can reduce a Li-ion battery’s ability to hold a charge, shorten its life, or kill it outright.

Don’t deep-discharge your battery

Not all discharge cycles exact the same toll on a battery. Long and heavy usage generates more heat, putting more stress on the battery; smaller, more frequent discharges extend the overall life of lithium batteries.

Slow and steady charge/discharge is best

As you now know, both fast discharging and fast recharging generate excess heat and exact a toll on battery life.

Whenever possible, carry a spare battery

If your device allows for easy battery replacement, carrying a spare battery is cheap insurance. It not only gives you twice the run time but also helps you avoid the need to fully discharge a battery or use a quick charge. When the in-use battery approaches 15–20 percent charge, simply swap out the drained battery for a fresh, cool one — you get instant full power, with no heat worries.
