Item number: 100739-U
Manufacturer: Keeppower
The 26650 Li-ion battery is a powerful large-format cell that has been developed for applications with high capacity requirements and long runtimes.
Keeppower 26650 E700 - 7000 mAh¹ 3.6V/3.7V Li-Ion battery - unprotected
Keeppower 26650-E700 is a high quality lithium-ion battery with a typical capacity of 7000 mAh¹. The cell is ideal for use in powerful LED torches, power banks, measuring devices, garden tools as well as industrial applications and DIY projects where compact energy sources with high energy density are required - provided the device is designed for unprotected 26650 cells.
Note: This cell is unprotected and has no integrated protection circuit (PCB/PCM²). It should therefore only be used in devices with their own protection circuit.

Scope of delivery:
1× Keeppower 26650-E700 - 7000 mAh¹ lithium-ion battery (flat top, unprotected)
Further features:
Lithium-ion batteries are the preferred choice in industry, household and mobility - thanks to their combination of performance, efficiency and reliability:
- High energy density - plenty of power in a compact design
- Low weight - ideal for mobile and portable devices
- Hardly any self-discharge - low losses during storage
- No memory effect - can be recharged at any time without loss of performance
- High cell voltage - 3.6-3.7 V per cell
- Universally applicable - from torches to industrial electronics
*Further options:
- Without extras: Battery cell without options as in the main picture.
- Raised positive terminal: A special welding process is used to weld a button (nipple) to the positive terminal, which raises the flat positive terminal by approx. 2 mm, similar to a normal battery (for an extra charge).
- Solder lug: A metal tongue that is firmly connected to the positive and negative terminals of the battery and is used to solder a connecting wire or additional batteries to the component (at an extra charge).
U - Both solder tags point in one direction (e.g. for parallel connection or soldering to electronic components)
Z - Solder tags point in opposite directions. (e.g. for series connection or soldering to components)
¹ The specified capacity of a battery indicates the amount of energy it can store under ideal laboratory conditions. This value is measured at a constant temperature and under defined conditions in order to create a reliable reference for the performance of the battery. These conditions are not met by commercially available test devices.
² PCB (Protection Circuit Board): Integrated protection circuit for single cells - protects against overcharging, deep discharge, short circuit and overcurrent.
BMS (Battery Management System): Extended protection for battery packs - including cell balancing, temperature control and communication with the device.
For safe applications, we recommend PCB-protected cells or a suitable BMS for battery packs.
The specified number of cycles is based on laboratory conditions. Actual values may vary depending on use, temperature and charging method. Example calculation: A battery with an initial capacity of 7000 mAh will only store around 80 % of its original energy after more than 500 - 1000 charging cycles, which corresponds to approx. 5600 mAh.
| Recommended standard charging current | 2A (2000mA) |
| Fast charging current according to specification | 3.5A (3500mA) |
| Standard discharge current | 1.4A (1400mA) |
| Charging operating temperature | 0 - 45 °C |
| Discharging operating temperature | -20 to +60 °C |
| Storage temperature | -20 to +20 °C |
Notes:
Charging lithium-ion batteries requires a special charger that charges the batteries using a special charging process. (CCCV = constand current, constant voltage.) The batteries must not be charged above a voltage of 4.2 volts, otherwise there is a risk of fire and explosion. It is advantageous to charge the batteries only up to approx. 4.1 volts, as this significantly increases the service life or number of charging cycles (possibly up to double). Only lithium-ion chargers may be used for charging. However, cheap chargers sometimes have the disadvantage that they do not switch off safely at the end of the charging process, but continue to charge the batteries with a low charging current, which can be dangerous.
Furthermore, rechargeable batteries and batteries do not belong in household waste! Please dispose of them as prescribed by law in the municipal collection centres or in the [usually green] containers provided for this purpose by retailers.
