How much capacity does a 18650 battery have?

How much capacity does a 18650 battery have?

The capacity of a 18650 battery is determined by something called the milliamp level, which can be abbreviated as mAh. The milliamp level of 18650 batteries typically ranges from around 2300 mAh to a maximum of 3600 mAh.

What is the highest capacity for 18650 battery?

The current maximum capacity of the 18650 battery can reach 3500mAh – 3600mAh. The highest capacity for an 18650 battery is the NCR18650G which clocks in at 3600mAh.

How long do 18650 batteries hold charge?

The total space time for 18650 until recharge for the most part is approximately one year. If you intend to store 18650 on a long-term basis, a storage charge close to 50 \% of the usable capacity ( ~3.7 V ) rather than 100 \% ( 4.2V ) will avoid faster deterioration of the battery.

How do you check lithium ion battery capacity?

1 Fully recharge battery until it reached it’s rated voltage(normally 4.2V); Set up cut-off current between 0.02C and 0.05C. 2 Discharge the battery until it reached it’s cut-off voltage (normally 2.4V); During this process, the discharge capacity is equal to battery capacity.

What is battery capacity?

Battery capacity (AH) is defined as a product of the current that is drawn from the battery while the battery is able to supply the load until its voltage is dropped to lower than a certain value for each cell.
