Securbox TS-12-18-AC is a maintenance-free lead-acid (VRLA) battery. It is a sealed battery in which the gases released during charging undergo a recombination process to form water, eliminating the need to refill it. It is made with AGM (Absorbed Glass Mat) technology, where the electrolyte is placed in fiberglass separators. The lack of liquid electrolyte allows the battery to be placed in almost any position.
The battery is dedicated for use in buffer power supplies. It can also be used as a cyclically recharged power source for autonomous or portable devices (charging voltage 14.1...14.4 VDC).
Key features
  • VLRA battery – maintenance-free, does not require maintenance such as topping up water, checking electrolyte,
  • can operate in any position,
  • service life of 3-5 years,
  • slow self-discharge process.
Please note:
The battery needs to be fully charged every 6 months. If it is not charged after this period, its capacity will decrease.
