## Safety notice

* Use only the DeltaQuad Dual Battery Charger. Do not use a NiCd or NiMH charger - Failure to do so may cause a fire, which may result in personal injury and property damage.

* Never charge batteries unattended unless you charge inside a Battery Safe. When charging Li-ion batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.
* If at any time you witness a battery starting to balloon or swell up, discontinue the charging process immediately. Disconnect the battery and dispose of it safely. Continuing to charge a battery that has begun to swell will result in fire. Likewise, never use a battery if you find it swollen or ballooned.
* Since a delayed chemical reaction can occur, it is best to observe the battery as a safety precaution. Battery observation should occur in a safe area outside of any building or vehicle and away from any combustible material.
* Wire lead shorts can cause a fire! If you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 1 hour. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the conductibility of electric current.
* A battery can still ignite even after 1 hour.
* A battery that makes a hissing sound is almost certain to ignite. Consider your own safety and that of your environment before attempting any action
* In the event of a crash, after a 15-minute period to ensure the battery was not compromised, you must remove the battery and dispose of it safely.
