Product Description

The UZB12.051 is a non-spillable maintenance-free VRLA lead-acid battery with
absorbent glass mat (AGM) technology.

Intended Use

The battery is intended to be used as a battery replacement for DC-UPS systems.
Check the product datasheet of the DC-UPS or the battery module to confirm that it is
suitable for the desired device.

Installation Instructions

Do not short-circuit the battery poles or power wires and always check correct battery
polarity.
Install the device in a cool area inside an enclosure providing protection against
electrical, mechanical and fire hazards.
Do not cover or block the pressure release valves of the battery. Do not install the
battery with the valve pressure releases on the bottom side. Hydrogen gas can be
released via pressure relief valves. It will form an explosive mixture in air when the
concentration exceeds 4% in volume. It is mandatory to ensure sufficient ventilation of
the battery. The necessary ventilation and air flow must be calculated according to EN
50272-2.
The device is designed for pollution degree 2 areas in controlled environments. No
condensation or frost allowed.
Do not store batteries or battery modules at temperatures higher than 25°C or
performance and lifetime may change.
Before initial use, check the last charging which is marked on the battery. If it is older
than 9 month, replace the battery.
Do not store batteries longer than 9 months without charging or performance and
lifetime may change. Every 9 months or whenever the open circuit voltage (OCV) falls
below 12.6V, the battery module should be charged. Apply a charging voltage of

13.8V (at 25°C) for 72 hours. Batteries with an OCV below 12V should be disposed.
Frequently charging below +5°C reduces the lifetime of the battery.

Instructions for disposal of batteries:

Always dispose batteries through a recycling organization. Optionally, batteries can
be returned to the supplier or the battery manufacturer. Batteries must be completely
discharged before recycling.
