PULS UZB12.051 Replacement Battery 12V/5Ah

This PULS UZB12.051 is a 12V 5Ah valve-regulated lead-acid (VRLA) battery with absorbent glass mat (AGM) technology, engineered as a reliable replacement energy source for compatible buffer modules. Its maintenance-free, spill-proof construction ensures safe operation in various orientations and simplifies handling.

Advantages

The AGM design immobilizes the electrolyte, allowing the battery to deliver consistent performance without periodic watering. It offers a long service life of 3-5 years under standard commercial use and can be stored for extended periods with minimal self-discharge (less than 3% per month at 25°C). The sealed, non-hazardous construction facilitates transport and installation.

Suitable for

• PULS buffer modules such as UB10.241 and UB20.241
• Uninterruptible power supply (UPS) systems requiring 12V backup
• Industrial automation and control applications
• Security and alarm systems
