introduction to deep cycle battery video, we discuss basic terms related to the batteries, both lead acid and lithium.
* How they are different than car battery
* Capacity - Amp Hours (Ah) and Watt Hours (Wh)
* Battery Condition - State of Charge (SoC) and Depth of Discharge (DoD)
* Charging Stages - Bulk, Absorption, Float, and Equalize
We’ll teach you the basics of what to look for when buying a portable battery bank. Power banks come in all sorts of sizes, from units the size of little lip balm tubes to some that are the size of car batteries. But finding the right battery bank isn’t as simple as selecting AA or 9-volt like you do with toys. Power bank ratings are displayed in milliamp hours or mAh. You’ll see they range from 2,000 to 20,000 mAh or greater. What does that number actually mean? Most smartphones have batteries in the 2,000-3,000 milliamp hour range. So with a 2,000 mAh power bank you can get about half a charge for your phone. If you’re wondering why this doesn’t add up, energy transfer isn’t perfectly efficient, energy will always be lost to heat and other factors. Even when your phone battery matches the size of your power bank, you probably won’t charge your cell phone to 100% with your bank. With a 20,000 mAh power bank you can expect to charge an iPhone or Galaxy about 8 times on a full charge of the power bank.
How quickly can a phone charge? You’ve likely seen terms like fast charge, quick charge, or something similar as a feature. What does that actually mean? Quick Charge Technology is a feature in some Qualcomm chipsets (found in Android phones) that allows you to safely charge a device up to 4 times faster than some standard chargers. The “fast” in “fast charging” is referring to the fact that it’s charging your phone using 2 amps instead of at ½ amp, the rate most chargers use. There’s some debate on whether or not charging in this fashion causes premature wear on the batteries.
