Note: Sony VTC4 IMR cells have a much lower internal resistance than regular 3.7V lithium ions. Voltage could go higher when charged on certain chargers such as the older versions of the WF-139 charger. Always check the voltage of your 18650 IMR battery after a full charge to make sure it is above 4.2V. You can use a multimeter to do this. Overcharging your Sony VTC4 above 4.25V may shorten the life cycle or even cause permanent damage to the product.

Safety Warning:

• Do not over-discharge or over-charge your battery.
• Recharge empty batteries (resting voltage of 3.6V) as soon as possible. Batteries that are fully drained and left in a discharged state for a long time could result in irreversible damage.
• Do not short circuit to prevent massive release of current.
• Do not dispose in fire.
• Do not leave unattended inside a vehicle.
• Do not store or carry your batteries in your pocket, purse or anywhere they can make contact with other metal objects.
• Do not leave unattended while charging.
• Discontinue use if the battery looks worn, torn, or is exhibiting unusual behavior.
