Prolonging your Battery’s Life

[Roland K]

Just a bunch of infos becaue, I tought battery longvity is best wehn always fully discarged. But I found that in a forum:

• Calibrate your battery with a full discharge every 30 charges to help the battery’s fuel gauge remain accurate. Run the battery down to the automatic cut-off point of your notebook before recharging.
• Avoid repetitive and regular full discharges. Li-Ion batteries will lose less charge capacity when partially recharged. Recharging at a 10 to 20% charge level is recommended.
• Disconnect the battery and store it in a cool, dry place. The optimal charge level is 40% for prolonged storage. Storing the battery with a low charge will result in permanent damage or battery failure.
• If you store your battery in a refrigerator, use a sealed plastic bag to keep moisture out. Allow the battery to warm to room temperature before using or recharging it.

Interesting -- did not know about storing it at 40%, wonder why that is? Thanks for sharing.

I have bought several devices with batteries that had round 40% of power... so it looks that part has some meaning.

Yes the storage of Lithium-ion batteries with at least this much power will avoid the full discharge which can ruin the device. This level will pretty much retain its level indefinitely.
