Safe chemistry LiMN 3.7V rechargeable battery is now available in R123 / 18500 /18650 /26500 size. These cells can handle high amperage and is safe to use in series / multi-cell applications. Can be charge with any LiIon battery charger with 4.2V output.
WARNING: There is no protection circuit on these batteries to control under or over voltage, just an anti explosion vent. Do NOT short Circuit! A Tremendous amount of current will be released. These are "safe chemistry" cells that will never "vent with flame" or catch fire on their own as they contain little oxygen unlike LiCo cells.
- Do not over-discharge/overcharge;
- Recharge empty batteries ( resting voltage below ~3.6V ) as soon as possible. Leaving LiIon batteries in discharged state will incur irreversible damage ( capacity / cycle loss );
- Do not short circuit ( will release tremendous current );
- Do not dispose of in fire.
LiIon Battery Charge Status
4.2V – 100%

4.0V – 75%
3.9V – 55%
3.8V – 30%
3.5V – 0%
Attention IMR USERS!!! : These IMR cells have much lower internal resistance than regular LiIon 3.7V cells and they may end up with a higher ending voltage when charged in certain chargers ( especially older version WF-139 charger ). Please check the voltage of them right out of the charger to see if they are above 4.20V when fully charged with your charger. Overcharging above 4.25V may shorten life/cycles. Above 4.50V may even pop them or making them leak. DO NOT use the charger if it seems to overcharge IMR cells.
I strongly suggest you purchase a Digital Multi meter to check your cell status. Please Read MDs-Lithium-Ion-gt-Incandescent-guide-compatability-comparison-chart before ordering. Written by a CPF expert
***DO NOT USE LiIon batteries if you don't know the dangers about them and how to handle them. on handling, charging, storage of LiIon batteries. Also bookmark http://batteryuniversity.com/learn/ for more info. Use at your own risk***
Use special caution when working with Li-ion cells, they are very sensitive to charging characteristics and may explode or burn if mishandled. Make sure the user has enough knowledge of Li-Ion rechargeable batteries in charging, discharging and assembly before use. Always charge in/on a fire-proof surface. Never leave charging batteries unattended. We only recommend using Lithium Ion rechargeable batteries with a control circuit (protection PCB) to assure safe charge, discharge, etc.
