Li-ion battery
HERMAN Battery Li-ion BL

Flexible battery system for the use of one battery:
within the given voltage level (10,8 V | 14,4 V or 18,0 V), batteries are interchangeable with each other, regardless of battery capacity or model

Perfect quick-clamping system:
enables quick replacement of accumulators with perfectly functioning latches

Nickel-plated connecting contacts of 3.6 V Li-ion cells in the battery case:
reliable and corrosion-resistant connection firmly fixed by spot welding

Temperature sensor in each accumulator:
when an inadmissible operating temperature is reached, the contact between the accumulator and the tool will be electronically interrupted. Contact recovery is automatic after the battery cools down

Load fuse in 14,4 V and 18,0 V accumulators:
does not allow the accumulator to be overloaded by excessive current consumption. It is therefore necessary to choose batteries with higher capacities for work that requires heavy battery loads

Battery charge status indicator:
it is in every tool, but you can also choose a battery that includes a charge status indicator

It is not necessary to mold them - that is, it is not necessary to charge and discharge them several times before first use, but we recommend that the first charge be carried out without interruption

Service life 1200 to 1500 charging cycles:
if used incorrectly, the service life can drop to a third. Li-ion batteries are especially harmful if they are completely discharged. When the voltage drops below the critical limit of 2.8 V, it is very difficult to revive it again, and when it is in such a state for a long time, "slow death" occurs, i.e. it discharges below the permissible value by self-discharge

The recommended working temperature range is from -18 to +50 °C. The optimal temperature for storage is in the range from -5 to +25 °C with a relative humidity of 60 +/- 20%, in a charged state at least 60%.
