How to prolong lithium-ion batteries?

• 1. Avoid frequent full discharges because this puts additional strain on the camcorder battery. Several partial discharges with frequent recharges are better for lithium-ion than one deep one. Recharging a partially charged lithium-ion does not cause harm because there is no memory. (In this respect, lithium-ion differs from nickel-based batteries.) Short battery life in a camcorder is mainly cause by heat rather than charge / discharge patterns.
• 2. Batteries with fuel gauge (camcorders) should be calibrated by applying a deliberate full discharge once every 30 charges. Running the pack down in the equipment does this. If ignored, the fuel gauge will become increasingly less accurate and in some cases cut off the device prematurely.
• 3. Keep the lithium-ion battery cool. Avoid a hot car. For prolonged storage, keep the canon camcorder battery at a 40% charge level.
• 4. Consider removing the battery from a camcorder when running on fixed power. (Some camcorder manufacturers are concerned about dust and moisture accumulating inside the battery casing.)
• 5. Avoid purchasing spare lithium-ion batteries for later use. Observe manufacturing dates. Do not buy old stock, even if sold at clearance prices.
• 6. If you have a spare lithium-ion battery, use one to the fullest and keep the other cool by placing it in the refrigerator. Do not freeze the camcorder battery. For best results, store the camcorder battery at 40% state-of-charge.
