Long-Term Storage

Long-Term Storage Lithium Accumulator

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.
