EVE 21700 5000mAh 3.6V Li-ion BUTTON TOP with PROTECTION

The EVE 21700 5000mAh Button Top Lithium-Ion Cell with Built-In Protection is a protected battery designed for use in high powered flashlights and other compatible devices. It features a button-top terminal and an integrated protection circuit that prevents overcharging, over-discharging, and short-circuiting. The cell has a 5000mAh capacity and follows EVE’s standard reliability specifications.

NOTE: These cells are slightly longer than the standard 21700 cell as they have a protection board located on the Negative end of the cell. This increases the total length to approx. 76mm. Please make sure your device will accept this length by cross referencing with your original cell or measuring the maximum length the battery compartment can accommodate (please factor in the mm of the terminal points).

As these cells are longer than the standard version, they may not fit in all chargers. Please click HERE to direct you to compatible chargers.

Usage & Charging

!!!!! IMPORTANT!!!!! These are immensely powerful batteries, and extreme care should be taken using them. Only use with brand name, quality chargers and equipment! Unfortunately, we cannot replace batteries that are damaged by non-compliant chargers or equipment. There are so many chargers on the market, we cannot possibly keep track of which ones will work with these batteries. You will have to contact the charger manufacturer to ensure it can charge these batteries without damaging them. Please ensure you only use these (or any other Lithium Ion) batteries with proper Lithium-Ion chargers and equipment. Lithium-Ion batteries can easily be damaged by charging them with too high current or exceeding the maximum rated current discharge. 

Use at your own risk. We do NOT accept any responsibly for damage, injury or death caused by improper use of these batteries!

• Do not overcharge!Ensure the charger voltage does not exceed the batteries stated full charge voltage.
• Do not over-discharge!Ensure the equipment you use do not draw more current than the batteries “Maximum Continuous Discharge Current”.
• Do not leave batteries discharged for a long period!Leaving Li-Ion batteries in a discharged state can incur irreversible damage – creating a loss in capacity and a loss in cycles.
• Do not short circuit your batteries!Short circuiting can cause a huge surge of current that will potentially burn out your battery, damage your equipment, and even cause serious injury to you!
• Do not let your batteries touch each other or other metallic items! Keeping your batteries loose, such as in your pockets, is a serious way to have your batteries fail and seriously harm you. There are battery holders and covers to keep your batteries safe.
• Do not dispose any battery in a fire! There are dangerous chemicals in batteries. If you try to burn your batteries, they will release dangerous fumes and will probably explode. Always dispose your old batteries to a battery recycling centre.
