Lithium Battery Safety
Lithium ion batteries are present in almost every portable electronic device you own. They are very high energy density, are low maintenance – they do not require scheduled cycling or have any memory effects that other battery chemistries have – and have the added benefit of being environmentally friendly, both in their cost-per-charge (the energy used to charge a battery is much less than the cost to manufacture and transport a lithium primary), and their direct environmental impact upon disposal.
That being said, the end user must exercise caution when using any lithium device, including a Muyshondt Power Cell.
- Always charge newly arrived batteries before using.
- Do not over discharge batteries. If you let a cell drain below 2.7 volts, you can cause permanent damage to the cell that will at best greatly reduce the life of the cell, and at worst cause thermal venting.
- If you ever discharge a cell below 2.7V, or are ever in doubt about cell damage, stop using the cell and dispose of it properly through a local battery recycler.
- Do not overcharge cells past 4.2V.
- Do not short circuit the positive and negative terminals.
- Only use a high quality charger designed specifically for lithium ion cells. It is recommended to charge cells at a 500mA rate to 4.1V, on a charger with a voltage readout.
- Avoid fully discharging the cells, as recharging from low state of charge decreases lifespan and capacity.
- Always follow all local regulations for proper disposal of lithium ion cells.
The MPC-18650P Power Cell is fitted with an electronic protection circuit that is intended to help improve safety. It is not a system designed for repeated abuse, and following the above guidelines will ensure safe, reliable operating of the Power Cells in our Electric Torches, and maximize the life and performance you get out of each cell.
The MPC-18350I Power Cell is an unprotected, IMR chemistry lithium-ion cell, and requires precautions on the part of the end user to ensure safe operation and longevity of the cell. You must follow all advice above closely - if you are ever in doubt, do not re-use the cell in any way, and dispose of it at your local battery recycler.

The MPC-CR2L Power Cell is a lithium primary cell. It is not rechargeable, and as with common batteries, should be disposed of properly with a local battery recycler when charge is depleted. Do not short circuit the terminals, disassemble, tamper with, or expose the Power Cell to high heat.
