Li-ion battery
HERMAN BL 18045A
18V | 2Ah

Slide-on quick-release system:
allows for quick battery changes with perfectly functioning latches

BMS (Battery Management System) control electronics:
continuously monitors and controls key operating parameters of the battery - in particular, safe and uniform charging and discharging of individual cells, as well as their protection against short circuit, overload, overheating and excessive discharge.

Battery charge status indicator:
allows quick checking of the charge status of even loose batteries

Nickel-plated Li-ion cell connection contacts in the battery case:
reliable and corrosion-resistant connection firmly fixed by spot welding

Integrated temperature sensor:
When the cell temperature limit range is exceeded (0 ~ 45°C), the battery output contacts are electronically disconnected. The connection is restored automatically when the cell temperature returns to the permissible range.

Recommendations for operation (discharging):
Optimal cell temperature range: 15°C to 30°C (highest capacity, lowest internal losses, longest life) Limit cell temperature range: −10°C to +50°C (at temperatures below −10°C, capacity drops significantly; at temperatures above 50°C, life is significantly shortened and cells degrade rapidly)

Charging recommendations:
Carry out the first charge without interruption. Optimal cell temperature range: 15°C to 30°C (ensures the most efficient charging and maximum cell life) Cell temperature limit range: 0°C to 45°C Note: Original chargers are equipped with an integrated cell temperature monitoring system. If the control system evaluates the temperature outside the limit range, the charging process is not initialized for safety reasons.

Storage recommendations:
ideally at room temperature (15°C to 20°C), relative humidity 60 +/- 20% and at a state of charge of 40-60%. Adhering to these conditions minimizes self-discharge, slows down cell degradation and extends their overall lifespan.

Lifespan 1200 to 1500 charging cycles:
if used incorrectly, the lifespan can drop by a third.A Li-ion battery is particularly damaged by a complete discharge. When the voltage drops below the critical limit of 2,8V, it is very difficult to revive it and when it is in this state for a long time, a "slow death" occurs, i.e. it is discharged below the permissible value by self-discharge.

⚠ Do not use non-original chargers or chargers from other brands to charge HERMAN batteries!
