What does Dell recommend for battery storage for a long period of time?

When storing for more than 4 days these guidelines can better preserve the life of your battery:
Such as Dell 3H625 Battery

Voltage: 14.8V

• Do not store batteries for long periods plugged into or attached to any power source. This includes AC adapters and laptop security carts plugged into an outlet. http://www.udtek.com/dell-3h625-battery-cells-4400mah-p-804.html
• Laptop batteries, including those stored in laptop systems, should maintain an Operational Storage Temperature of 0° to 35°C (32° to 95°F).
• Batteries may be stored in the laptop or outside of the laptop.
• Charge batteries before storing. The recommended charging time should not exceed 1 hour. Typically, this should charge the battery to between 80% and 100%. (Some discharge will take place over time. Stored batteries are expected to discharge 10-15% over a four month period, for your information.)http://www.udtek.com/dell-3h625-battery-cells-4400mah-p-804.html
