Batteries will only have test charge. Ensure batteries are fully charged to reach full capacity. Failure to do so may lead to long term cell issues.

We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

• Do not overcharge! Ensure the charger voltage does not exceed the batteries stated full charge voltage.
• Do not over-discharge! Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
• Do not leave batteries discharged for a long period! Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
• Do not short circuit your batteries! NEVER short circuit Li-Ion batteries! Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
• Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
• Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
