Hohmtech Works² 18650 2547mAh max. 35.8A Lithium-ion battery NMC, 3.6V - 3.7V
Item number: 100835
Hersteller: HOHMTECH
The batteries, which are primarily manufactured for e-cigarettes, are characterised by very high safety standards. The batteries would have to pass a series of certifications, including the IEC certificate required for medical equipment. Due to its specifications, the individual battery allows use in the e-cigarette up to 73W or pulsed (6s) max. 105W.
The 18650 HohmTech WORK² batteries offer superior safety up to max. 35.8A.
The exactly stated key figures have become a trademark in the meantime. The batteries achieved high popularity and breakthrough on the market in the USA, where the company's headquarters are located. In a survey of the most respected E-zig. Forum on popularity and confidence in the market, HohmTech batteries took first place.

Safety instructions:
Lithium cells may only be operated with protective electronics!
Please note that lithium cells may only be used by authorised specialist personnel.
Incorrect handling or short-circuiting can lead to fire or explosion.
Further characteristics:
Lithium-ion batteries are thermally stable and are not subject to any memory effect.
They work on the basis of lithium and are characterised by a high energy density.
Scope of delivery:
1x HΩ WORK² - 2547mAh, lithium-ion battery
| Charging current Normal (recommended) | 0.xx - 2A (2000mA ) |
| max. charging current | up to 3.8A |
| Operating temperature charging | 0 °C - 60 °C |
| Operating temperature discharging | -40 °C - 60 °C |
Notes:
A special charger is required for charging lithium-ion batteries, which charges the batteries according to a special charging procedure. (CCCV = constant 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 the number of charging cycles (possibly up to double). Only lithium ion chargers may be used for charging. However, the 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 small 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 at the municipal collection points or in the [usually green] containers provided by retailers.
