What are some common misconceptions about battery life?
People used to think that you had to “train” your battery to make sure it would take the most charge. To do that, people would drain it regularly and charge it — and they’d never plug it in when it was over 50%. The thought was that over time, the battery would develop a memory and allow for just a percentage of the charge.
Why does a cell phone battery get shorter as it ages?
In fact, age is the primary reason your battery life gets shorter as your phone gets older. You shave a second or two off of your phone’s maximum battery capacity every time you charge it. Batteries use chemical reactions to store and process energy and no chemical reaction is infinite.
What does the Apple logo mean when battery is dead?
When I go to restart it, at first it indicates that the battery is completely dead. However, then the apple logo appears and it successfully restarts, showing the battery is 100% charged.
When do you know if your car battery is dead?
After that half-hour, when you are stopped at home or in a safe place, do a little test. After you turn the engine off, wait at least a minute, then start it again. Wait another minute and start it another time or two to make sure that you won’t be stranded at the gas station or wherever you go next.

What causes a battery to go bad after a long time?
But if the battery has been dry for a long time, it can cause a problem. When the plates in the cells are exposed to oxygen, it rapidly causes sulfation to build up. Sulfation is the number 1 cause of early battery failure. Plus, charging a dry battery will burn it up.
How long does a Ni-Cad laptop battery last?
Older laptops using Ni-Cad and early Ni-MH batteries often ran for 2.5 to 3.5 hours when brand new, but within a month or so, would barely keep the notebook powered up for an hour. Newer laptops using Ni-MH and Li-ION batteries are much better, often holding onto a three hour life through hundreds of charge and discharge cycles.
Can a car battery outlast an EV battery?
In many cases, EV batteries are already outlasting the cars they are being put in. Hans Eric Melin, the founder of Circular Energy Storage, a market research firm focused on second-use and recycling of lithium-ion batteries, says that it’s “very unusual” for a car to be pulled off the road today because its battery has degraded fully.
