BU-808a: How to Awaken a Sleeping Li-ion
Li-ion batteries contain a protection circuit that shields the battery against abuse. This important safeguard also turns the battery off and makes it unusable if over-discharged. The material on Battery University is based on the indispensable new 4th edition of "Batteries in a Portable World - A Handbook on Rechargeable Batteries for Non-Engineers" which is available …
Internal Resistance Calculator
The internal resistance of a voltage source (e.g., a battery) is the resistance offered by the electrolytes and electrodes of the battery to the flow of current through the source. The internal resistance of a new battery is usually low; however, as the battery is put to more and more use, its internal resistance increases.
