The battery pack BP-2425N serves to store energy for the UPS PC power supplies eNSP3-450P-RS and eNSP3-450P-USB. It is the optimal solution when a long service life of the battery pack is required at rather high ambient operating temperatures. The equipped CYCLON cells are based on a special lead-tin alloy which results in a service life of up to 10 years in stand-by mode. Due to its low self-discharge a fully charged battery pack can be stored for up to 1 year.
