15 battery facts you didn’t know until now

By Team Ventev Topic: Tech Specs

February 18 is National Battery Day. What better way to celebrate than to recharge your mind with these 15 facts about them?!

1. The first widely-used battery was the Daniell Cell, produced in 1836. It powered the popular objects of the era: telegraphs and telephones. Which are basically, old school text messages and phone calls. So we’re still using batteries for the same things today.

2. Eveready brought the first alkaline battery to market in 1955. Learn about all the development that came before it.

3. Cold does slow the rate of self-discharge, but not enough for it to actually make your batteries last longer. So tell your mom to take the AAs out of the fridge.

4. Speaking of temperature, AAA notes the majority of service calls are related to dead car batteries. That number doubles in cold weather.

5. The Energizer Bunny was born in 1989. He turns 27 this year.

6. The first cell phone could only provide 20 minutes of talk time before the battery died.

7. There are numerous types of batteries available today, but the main ones used in commercial applications are Alkaline, Lithium Ion, Lithium Polymer, Nickel Cadmium, Lead-Acid, and Nickel-Metal-Hydride.

8. The battery in the beloved Nokia 5110 was 600 mAh. For comparison, the battery in an iPhone 6 is three times that – 1,810mAh.

9. The inventor of the Lithium Ion battery has not won a Nobel Prize, though many think he should’ve. But at 92, he might get another chance.

10. In November 2015, Popular Mechanics tried to figure out how many AA batteries it would take to jump start a car. Find out if it’s more or less than you think.

11. Uber drivers will usually jump start a dead car battery. Just make sure you’re carrying a set of jumper cables and call before he arrives to ask if it’s okay.

12. The biggest threat to battery life is exposure to extreme temperatures.

13. The average lifespan of a LiPo smartphone battery is 300-500 cycles. Battery life is measured in cycles instead of days due to the nature of their charge/discharge cycle.

14. The letter designations for batteries (AA, AAA, D, etc.) come from the American Standards Association, which preceded the American National Standards Institute (ANSI).

15. In general, a battery consists of an enclosure, anode, cathode, electrolytes and separators. They’re typically made from the following materials:

  • Enclosure: stainless steel
  • Anodes: graphite, copper or nickel foil, binders
  • Cathodes: cobalt, manganese, nickel, phosphate
  • Electrolytes: lithium salt in a solution
  • Separators: fiberglass cloth or flexible plastic films made from nylon, polyethylene or polypropylene
