Long-term energy storage with low voltage cut-off
Extremely low self-discharge and very long shelf life
As a rule, lithium-ion batteries have a self-discharge rate of about 4% per month. This means that for long-term use only 52% of the capacity per year is available and a second, additional battery would be necessary for the given capacity requirements.
In comparison, our long-term memory has a self-discharge rate of only 4% per year and can therefore be available for several years without recharging, e.g. as a backup!
The battery can be charged and discharged in a temperature range from -20 to +60°C
Most batteries cannot be charged below 0°C. This is a big advantage of our battery for outdoor applications in combination with e.g. solar cells, because even at low temperatures energy can be supplied by the PV module.
High degree of safety
The accumulator does not tend to develop a fire or even an explosion.
Applications Long-Term Storage
which are difficult to access due to their regional location and yet need to reliably record or send data.
Emergency Power Supply
e.g. emergency lighting, which must work reliably and maintenance-free for years
Outdoor Power Supply
of measuring systems such as weather stations, which are exposed to high temperature differences
for all types of surveillance in vehicles, traffic and transport
A reliable self-sufficient energy supply is becoming increasingly important in many areas.
New technologies offer unimagined possibilities here!
such as warning signs, signal lights, tunnel lighting, etc.
