NOTES:

• Please FULLY CHARGE your rechargeable batteries before first use. When in doubt, leave your batteries to charge overnight (8 hours) to ensure a full charge.
• Please FULLY CYCLE your Li-ion batteries (fully charge, then fully discharge them) at least once before regular use. To discharge your battery, please simply use the battery in your device as normal, but do not recharge your battery until it is complete discharged and your device no longer operates.
• Please FULLY CHARGE your batteries a SECOND TIME after completing a cycle. Once this second charging is complete, you may now use and/or charge your batteries as much or as little as needed, all without fear of creating a memory.
• DO NOT full charge your Li-ion batteries before storing them for long periods of time. Discharge them close to half a charge first.
