What do the numbers on lithium batteries mean?
The number is in milliamp hours, or mAh. If your battery has 1 amp hour, that means it can discharge 1 ampere of current over one hour, or half an ampere an hour for two hours, etc. This battery is rated at 3,200 mAh, meaning that in one hour, it can discharge 3,200 milliamps (3.2 amps) and then it’s done.
How long does a lithium battery last?
about two to three years
The typical estimated life of a Lithium-Ion battery is about two to three years or 300 to 500 charge cycles, whichever occurs first. One charge cycle is a period of use from fully charged, to fully discharged, and fully recharged again.
What is the size of the lithium ion battery?
For Li-ion rechargeable batteries, the most common sizes are the 18650 (18mm diameter, 65mm length), the 26650 (26mm diameter, 65mm length), and the 21700 (21mm diameter, 70mm length). Cylinders are symmetrical, have a robust mechanical form, and can be efficiently packed.
What are the different sizes of lithium ion batteries?
What do you need to know about battery specifications?

How to find the laptop battery specifications-computer hope?
How to find the laptop battery specifications. There are different types and sizes of laptop batteries. To determine what laptop battery you have, remove the battery from the laptop and look at the top or bottom of the battery. The Dell battery, pictured here, is a Li-ion battery.
What should the discharge current be on a lithium ion battery?
Simply put, the more current you draw from your battery, the less mAh you’ll be able to get out of it. That’s why you should always look at the discharge current they quote in the Notes section. They obtained this number by discharging the battery at 0.65A discharge current.
