How to charge Lithium batteries?

How to charge Lithium batteries?

Very typical question I receive in my email: How do I charge Lithium battery?

Lithium Battery replacement

Lithium Battery replacement

How do I replace Li battery and make my device functional again?

Lithium ion/polymer Battery Cycle Life and what might influence that.

Lithium ion/polymer Battery Cycle Life and what might influence that.

Here we going to discuss parameters, which will influence Battery Cycle Life and Battery Shelf Life for Li batteries.

Custom sized battery

We do make custom sized batteries.

What do you need to know before you send us an email?

Possible falures in Lithium batteries

Possible falures in Lithium batteries

Here I will try to briefly describe possible battery failures and why it happened.

Li-po, Li-ion Battery Capacity needed for given Load Currents, approximation calculator

Li-po, Li-ion Battery Capacity needed for given Load Currents, approximation calculator

This is a simplified battery capacity calculator to estimate the needed battery capacity if you have known load currents. You need to know: a. Time needed to run your loads in hours b. Load currents in A.

Battery run-time calculator for Li batteries

Battery run-time calculator for Li batteries


This is a simplified run-time calculator to estimate the run-time of your loads for Li batteries. You need to know: a. Battery capacity in mAh (mili Amp hours) b. Load currents in mA.

Please note 1Ah=1000mAh and 1A=1000mA. So if you have large car battery with 20Ah capacity, then put 20000  (mAh) as a number.

Lithium Iron Phosphate (LiFePO4) batteries, method of charging and properties

Lithium Iron Phosphate (LiFePO4) batteries, method of charging and properties

Lithium Iron phosphate batteries are safer than Lithium-ion cells, and are available in a range of cell sizes between 20mAh and 100 AH with much longer cycle life than conventional batteries.
