| 634125 | 2008-01-26 11:55:00 | I have two Sony infoLITHIUM batteries that won't hold their charge anymore. I charged one, and the when the indicator showed full, I removed the power cord. But when I turned on the camera, after a few seconds the "low power" picture showed up and it turned off. The other battery, when plugged into the charger the light would blink on and off and would not charge at all. What a shame because they are practically new, I have only used them once or twice before storing them. Anyway so I was wondering if anybody knows how to revive them? They are Li-ion batteries. Thanks | mlp (12595) | ||

Li-Ion are not suitable for long term storage - chemical action degrades them over time regardless of use. If you do wish to store them, get them to a 40% charged state, and keep them in the fridge. Give them a charge - discharge cycle every couple of months and you will slow the degradation somewhat. If stored fully charged, internal copper plating reduces their capacity, storing flat degrades them a bit quicker due to chemical dissolving of the active bits. When they age or otherwise degrade, bin them. They do not revive at all. They are great for lightweight compact energy storage for regularly used medium to high load applications. Bad for sitting on the shelf. |
