- AGM (Absorbent Glass Mat) technology - electrolyte trapped in fiberglass separators.
- Maintenance-free design, sealed housing and no electrolyte leakage.
- Designed for buffer operation in alarm, CCTV, UPS and automation systems.
- Capable of operating in various positions (except for pole-down operation).
- Long design life with proper expLoatation and charging selection.
Purpose and applications
Alarmtec's BP Series 12V 18Ah AGM battery is designed primarily for buffer operation in burglar alarm systems, control panels, buffer power supplies, CCTV systems, gate automation, emergency lighting and other installations requiring reliable 12-volt voltage backup. It can also be used in cyclic mode in a lower frequency of charging and discharging, while maintaining proper charging parameters.
Thanks to the use of AGM technology, the battery is characterized by low self-discharge, good resistance to shock and vibration, and the ability to work indoors, as it does not emit excessive gases during proper charging. It is an ideal solution for installers and end users looking for a reliable emergency power supply for critical security systems.
Design and manufacturing technology
The Alarmtec BP series battery is built with a sealed housing made of damage-resistant plastic, inside of which are lead plates and electrolyte absorbed in fiberglass separators (AGM). As a result, the electrolyte is not in a liquid state, which minimizes the risk of leaks and allows the battery to be mounted in different positions.
The maintenance-free design means there is no need to refill the electrolyte or perform electrolyte inspection services. The control valves used (VRLA) protect against excessive pressure build-up inside the case and allow safe expLoatation under typical buffer operating conditions, provided the correct charging voltage is used.
ExpLoatation, charging and durability
Alarmtec's BP Series 12V 18Ah AGM battery requires the use of proper charging parameters depending on the mode of operation. In buffer operation, a constant charging voltage selected according to the manufacturer's specifications is recommended, usually in the range of about 13.5-13.8 V at the reference temperature to maintain full capacity and extend service life. In cyclic operation, a higher charging voltage is used, typically in the range of about 14.4-15.0 V, with control of charging time and current.
The design life of the battery in buffer operation is several years, depending on ambient temperature, depth of discharge and the quality of the charger used. The most favorable operating temperature is around 20-25°C; any increase in temperature significantly shortens the life, and deep discharges below the recommended terminal voltage can permanently reduce capacity. Regular monitoring of the resting voltage and avoiding prolonged storage in a discharged state are key to maintaining battery performance.

FAQ (customer)
- Q: Is this battery suitable for alarm systems?
A: Yes, it is designed primarily for buffer operation in alarm panels and backup power suppLies for security systems. - Q: Can I use this battery in a small UPS?
A: It can be used in UPS devices as long as the charging voltage and battery type match the UPS manufacturer’s specifications. - Q: Do I need to refill the electrolyte in this battery?
A: No, it is a maintenance-free AGM VRLA battery and does not require electrolyte refilling. - Q: How long will the battery last in my system during a power outage?
A: Backup time depends on the load power; to estimate it, you need to know the current drawn by your devices and compare it with the 18 Ah capacity. - Q: Can the battery be installed on its side?
A: Yes, AGM construction allows operation in various positions, except with terminals facing downwards. - Q: How often should I repLace this battery in a typical alarm system?
A: In normal buffer operation and room temperature, repLacement is usually needed every few years, depending on usage conditions.
FAQ (expert)
- Q: What charging voltage should be used in float mode for this 12 V AGM battery?
A: The recommended float voltage is in the typical range of about 13.5–13.8 V at 25°C, following the producer’s specification for VRLA AGM batteries. - Q: What is the recommended cyclic charging voltage range?
A: In cyclic operation, the charging voltage should usually be in the range of approximately 14.4–15.0 V at 25°C, with proper current limitation. - Q: How does ambient temperature affect the service life of this battery?
A: Every significant increase above 25°C noticeably shortens the service life; continuous operation at elevated temperatures can reduce lifetime to a fraction of the nominal design life. - Q: Is this battery compatible with EN or IEC standards for VRLA batteries?
A: It follows typical construction and operating parameters of sealed lead-acid VRLA AGM batteries and can be integrated into systems designed for such standard batteries. - Q: Can this battery be used in cyclic appLications such as small traction or mobility devices?
A: It can be used in light cyclic appLications, but it is optimized for standby use, so for intensive cycling a dedicated deep-cycle battery is recommended. - Q: What precautions should be taken regarding deep discharge?
A: The battery should not be discharged below the recommended end-of-discharge voltage (for 12 V blocks typically around 10.5 V), as repeated deep discharges significantly reduce capacity and lifetime.
