You must read these safety instructions and warnings before using or charging your batteries. If you do not agree with these conditions, you must return the battery immediately to the seller before use.

Lithium Polymer and Li-ion batteries are volatile. Failure to read and follow the below instructions may result in fire, personal injury and damage to property if charged or used improperly. By purchasing Booster Batteries, Inc Lithium Polymer and Li-ion batteries, the buyer assumes all risks associated with lithium batteries.

Li-Ion and Polymer battery & packs may explode and cause fire if misused. All persons performing the installation of Booster Batteries for their intended use must be experienced professionals and assume all responsibility for proper installation, as well as have the capability to provide services in the event of an emergency.
1. When charging Battery Pack, put the battery in a fire proof container. Don’t leave battery pack and charger on wood or carpet, or leave it unattended.
2. Keep Li-Ion & Polymer battery packs away from children.
3. Never make wrong polarity connection when charging and discharging battery packs. Always double check polarity of battery’s connector to ensure proper polarity. Always check first with a Volt-Ohm multimeter.
4. Lithium batteries have a cycle life, replace old batteries with new ones when they reach the end of their service life or when two years old, whichever occurs first.
5. Testing battery condition is your own responsibility. Test the lithium battery received before using to ensure battery can be operated properly and safely. Refer to the UL safety test standard for lithium batteries and packs. For more information, contact Underwriters Laboratories directly.

General Guidelines and Warnings
1. Use specific Lithium Polymer/Li-ion charger only. Do not use a NiMH or a NiCd charger- Failure to do so may a cause fire which may result in personal injury and/or property damage.
2. Never charge batteries unattended. When charging lithium batteries you should always remain in constant observation to monitor the charging process and react to potential problems that may occur.
3. It is your responsibility solely to ensure that the charger you are using to charge the batteries works properly. Always monitor charging process to assure batteries are being charged properly. Failure to do so may result in fire.
4. If at any time you witness a battery starting to balloon, swell up, smoke or hot, discontinue charging process immediately, disconnect the battery and observe it in a safe place for approximately 15 minutes.This may cause the battery to leak, and the reaction with air may cause the chemicals to ignite, resulting in fire.
5. Since delayed chemical reaction can occur, it is best to observe the battery as a safety precaution in a safe area outside of any building or vehicle and away from any combustible material.
6. Wire lead shorts can cause fire! If you accidentally short the wires, the battery must be placed in a safe area for observation for approximately 15 minutes. Additionally, if a short occurs and contact is made with metal (such as rings on your hand), severe injuries may occur due to the electrical conductibility of metal.
7. A battery can still ignite even after 10 minutes.
8. In the event of a strong jolt to the battery, such as from a vehicle crash, you must remove battery for observation and place in a safe open area away from any combustible material for approximately 15 minutes. Never drop the batteries.
8. If for any reason you need to cut the terminal wires take care to cut each wire separately to ensure the wires to not touch each, otherwise or a short may occur and potentially cause a fire.
9. Never store or charge battery pack inside inside a closed space during extreme temperatures, since extreme temperature could ignite a fire.

Charging Process
1. Never charge batteries unattended.
2. Put battery in the fireproof container and charge in an isolated area, away from other flammable materials. Always have fire extinguisher for emergency use.
3. Let battery cool down to ambient temperature before charging.
4. Do not charge batteries packs in series. Charge each battery pack individually. Failure to do so may result in incorrect battery recognition and charging functions. Overcharging may occur and fire may be the result.

Storage & Transportation
1. Store battery at room temperature between 40 and 80 degrees F for best results.
2. Do not expose battery pack to direct sunlight (heat) for extended periods.
3. When transporting or temporarily storing in a vehicle, temperature range should be greater than 20 degrees F but no more than 150 degrees F.
Storing battery at temperatures greater than 170 degrees F for extended periods of time (more than 2 hours) may cause damage to battery and a possible fire.

Battery Life
Batteries that lose 20% of their capacity must be removed from service and disposed of properly. Discharge the battery to 3V/Cell, making sure output wires are insulated, then wrap battery in a bag for disposal.
