Product detailed description

GeB Li-Ion Battery 18650 3000mAh 3.7V

This is an original GeB 18650 rechargeable lithium-ion battery with a capacity of 3000mAh.

We spent several months searching for a quality 18650 battery with a good balance of power and capacity. Here is one of the flashlights we selected. 18650-3000 from GeB has a large capacity - 3000mAh and can handle continuous discharge, up to 3A. You can, of course, find other higher capacity 18650 batteries on the market, but most will either have a much smaller continuous discharge current or cost significantly more, or be a fake with a fraction of the capacity of the original.

These batteries do not have built-in protection circuits. We recommend using our TP4056 Li-ion cell charger with protection. This gives the batteries the protection they need.

When you get your batteries from us, they will be partially charged by us (60-80%). This will extend the battery life during storage. If you don't intend to use the batteries right away, you can leave them as they are. However, we recommend that you charge the batteries before use.

Included in delivery:

• 1pc GeB Li-Ion Battery 18650 3000mAh 3.7V

Notes:

• The battery or accumulator that may be included in the product is subject to a six-month lifetime as it is a consumable.
• Due to the nature and characteristics of Lithium Polymer batteries, these batteries are not returnable, and LaskArduino is not responsible or liable for any damage, defects, injury, fire, skin burns, or any other consequences that may occur from the improper use of these batteries or any device or item with which you use the battery, including following or using any instructions, directions, or advice of any kind from LaskArduino or others. By purchasing this product you accept the previous.
• Do not use with NiMH/NiCd chargers! Never charge or use unattended. Always check the battery and circuits for damage, broken wires and short circuits. Like all polymer batteries - they should be used by professionals.
• Important: You must do everything you can to prevent the battery from overcharging and short-circuiting. This could cause permanent damage. If you hadn't intervened in time, the battery could have caught fire and burned up. Because these batteries are round in shape, care must be taken to avoid problematic situations, e.g.: sliding off the table, falling, dents, etc.
• You have to be careful when connecting two cells in parallel. Both cells must have the same voltage. If one cell has a lower voltage, the discharge would be at the lowest possible discharge limit so that - if possible - both cells have the same voltage. In this case, the tension will be balanced. If the voltage of the two cells is very different, it can cause overheating of the cell or even worse. When charging two cells in parallel to this module, the charging current of each cell is half of the total charging current of the module, i.e. each cell has the same voltage level.

The manufacturer of our lithium batteries gives the following warnings and cautions:

• Do not immerse the battery in water or other liquids. Keep the battery in a cool, dry place
• Do not use or store the battery close to any heat source
• Use a charger that clearly states that it is compatible for charging the battery and has appropriate charge protection (voltage, current)
• Do not install the battery with reverse polarity
• Do not connect the battery to an electrical outlet or other incompatible source
• Do not throw the battery into fire
• Do not short-circuit the battery = do not connect the positive and negative poles to each other with conductive material
• Do not transport or store batteries with metal objects such as hair clips, necklaces, or any other conductive object or material,
• The battery must not be mechanically damaged, so do not throw it, squeeze it, puncture it, etc.
• Lithium batteries should only be used with voltage, current, and thermal protection
• Do not use or leave the battery in a high temperature environment (e.g. in direct sunlight or in a vehicle in hot weather). Failure to heed this warning may result in battery overheating and/or fire or explosion. It will also reduce battery capacity and affect battery life
• If electrolyte spills and gets into the eyes, rinse and wash eyes with clean water and seek medical attention immediately
• If the battery smells, gets hot, changes color or shape, or in any way shows abnormal changes during use, charging or storage, remove it immediately from the charger, devices and stop using it
• If the battery contacts are dirty, clean the contacts with a dry cloth before use
• Be aware that discarded batteries can cause a fire or explosion. For this reason, before disposing of the battery, insulate the battery contacts with a suitable insulating material, e.g. insulating tape
