Li-Ion/LiPO Important Warning & Disclaimer
IMPORTANT!!! Take proper precautions when handling Lithium-ion (Li-ion) /Lithium Polymer (LiPo) batteries, as they are different than NiMH or NiCd batteries! Failure to follow these instructions can result in severe or permanent damage to battery, cause serious personal injury, or lead to fire.
Thank you for purchasing a RGN Pro System equipped with a Lithium-ion (Li-ion)/Lithium Polymer (LiPo) battery. By purchasing this product, the buyer/user agrees that he/she has read and understood the safety precautions available on our website (retrogamingnow.com/lithium-batteries), that he/she bares full responsibilities of these risks, and does not hold Retro Gaming Now, its distributors, or its retailers responsible for any accidents, injury to persons, or property damage that may occur. Damage from misuse or modifications will void your warranty and can cause serious injury.
General Safety Guidelines
- 1) NEVER use a NiCd/NiMH charger to charge Li-ion/LiPo batteries. Use a charger designed for charge LiPo/Li-ion batteries only.
- 2) ALWAYS inspect the battery to ensure there are no signs of damage, deformity, or swelling before charging. If there are, do not continue charging the battery, and follow the proper procedures to dispose of the battery.
- 3) ALWAYS charge batteries in a fireproof container and away from combustible material. Do not charge on surfaces that can catch fire – this includes: wood, cloth, carpet, or in the application’s device.
- 4) NEVER charge batteries unattended. Always remain in constant observation of the charging process & react to potential problems that may occur.
- 5) NEVER charge a deformed, swollen or ballooned battery. Continuing to charge a battery that has begun to swell will result in a fire. Follow these steps:
a. STOP the charging process by unplugging the charger, and disconnect the battery from it immediately
b. Disconnect battery from the device immediately.
c. Place it in an open non-flammable area.
d. Watch it for approx. 30 minutes from a safe distance.
e. Follow proper procedure to dispose of battery
- 6) NEVER allow the battery’s positive and negative leads to touch. This can cause the batteries to short and lead to fire!
- 7) If for any reason you need to cut the terminal wires of an assembled Li-ion/LiPo battery pack, it will be necessary to cut each wire separately, ensuring the wires to not touch each other or a short may occur
- 8) Store Li-ion batteries in a cool, dry place between 40-80° F.
- 9) NEVER store Li-ion/LiPo batteries in any locations that can exceed these temperatures such as a vehicle, garage, or in the sun.
- 10) Keep your batteries out of reach of children and pets.
Avoid Over-Discharging Li-ion/LiPo Batteries
Over-discharging a Li-ion/LiPo Battery, or continuing to use the battery even after it is fully depleted (e.g. when it is below its minimum voltage level), can cause permanent damage to your battery.
While you’re not able to visibly detect the internal damage to the battery, it can eventually cause a fire when attempting to re-charge at a later time.
Caution – Before Charging
- 1) Visually inspect your Li-ion/LiPo battery for any damaged leads, connectors, shrink wrap, swelling of cells, or other irregularities.
- 2) If you find any of the above issues with your pack, stop using it at once.
- 3) NEVER leave batteries charging unattended. Always remain in constant observation of the charging process and react to potential problems that may occur.
- 4) Allow the battery to cool down to ambient temperature before charging.
C-rating is a standard which defines a battery's operating current based on its capacity. 1C is the current it takes to approximately fully discharge a battery in 1 hour, and is simply defined by dropping the "h" in the pack's capacity (e.g. 1C for a 1000mAh LiPo battery is 1000mA, or 1A). The examples below demonstrate how to figure out the proper charging current for different packs:
i. 900 mAh LiPo Batteries -> Charge at or below 900 mA
ii. 1300 mAh LiPo Batteries -> Charge at or below 1300 mA, or 1.3 A
iii. 2200 mAh LiPo Batteries -> Charge at or below 2200 mA, or 2.2 A
Battery Maintenance & Handling
- Never dissemble existing Li-ion/LiPo battery packs to mix with other Li-ion/LiPo cells/packs.
- Only charge your Li-ion/LiPo battery with a good quality, dedicated Li-ion/LiPo charger. A poor quality charger may not be able to charge or protect your battery properly, and can be dangerous.
- Do not discharge battery to a level below 3V per cell under load. Deep discharge below 3V per cell can deteriorate battery performance.
- Charge: 32 to 113°F
- Discharge: 32 to 140°F
- Let battery cool down to ambient temperature before charging.
- During discharge and handling of batteries, do not exceed 160°F.
Storage & Transportation
- Never store batteries near an open flame or heater.
- Store battery at room temperature between 40 and 80°F for best results.
- Do not expose battery pack to direct sunlight (heat) for extended periods of time
- When transporting or temporarily storing in a vehicle, temperature range should be greater than 20 °F but no more than 150°F.
- Storing battery at temperature greater than 170°F for extended periods of time (more than 2 hours) may cause damage to battery and possible fire.
- For long term storage, do not store them fully charged; it is recommended to fully charge and then discharge it to 50-60% of their capacity.
- Battery Life & Disposal of LiPo Batteries
- Rechargeable Li-ion/LiPo batteries do not last indefinitely. Batteries that have lost 20% of their initial capacity should be removed from service and disposed of properly.
- If at any time you detect any physical damage to a Li-ion/LiPo battery such as swollen cell, split, battery leak, or tear in the LiPo cell’s foil covering, STOP and do not continue discharging the battery.
Proper Disposal of Li-ion/LiPo Batteries:
Regulations and laws pertaining to the recycling and disposal of Li-ion/LiPo batteries vary from country to country as well as by state and local governments. You should check the laws and regulations where you live.
There are a number of facilities that recycle Li-ion/LiPo batteries. The Rechargeable Battery Recycling Corporation's web site, www.rbrc.org, is an excellent source for finding a facility to handle these types of batteries. If you are not sure if your waste facility can handle Li-ion/LiPo batteries, contact them and verify if they are permitted or not.
Remember that before any type of disposal the batteries should be discharged completely. Tape the contacts with electrical tape and package so as to prevent contacts accidentally coming together at any time
For home disposal, many stores offer free recycling of rechargeable batteries. If no outlet is available in your area, it is safe to dispose of these batteries in your regular trash. As always, check with your local laws to make sure that this is acceptable.
