## Long description

The ULTRACELL 12V/3.4AH-UL is a sealed lead‑acid rechargeable battery with a nominal voltage of 12 V and a rated capacity of 3.4 Ah. It is designed for standby and backup applications where compact, maintenance‑free power is required. The valve‑regulated sealed construction prevents electrolyte leakage and allows installation in various orientations, making it suitable for small UPS units, alarm and security systems, emergency lighting, and portable devices that need reliable short‑term power.
Advantages
This sealed lead‑acid battery delivers stable output at 12 V with a compact form factor and maintenance‑free operation. Valve regulation and internal recombination reduce gas release under normal use, while the rechargeable design supports repeated charge/discharge cycles common in standby power applications. The battery’s robust construction provides consistent performance in confined installations and low‑to‑moderate discharge scenarios.
Suitable for
 Small uninterruptible power supplies (UPS) for home or small office equipment
 Alarm, security and intruder detection systems
 Emergency and exit lighting fixtures
 Portable measurement devices and handheld equipment requiring 12 V backup
 Low‑power telecom or networking backup modules
When it may not be suitable
This battery is intended for standby, cycling and low‑to‑moderate current applications. It is not designed for high‑current starter duties such as automotive engine starting where very high discharge currents are required. It may also be unsuitable for continuous deep‑cycle use in heavy load applications unless specified by the equipment manufacturer.
Key specifications
 Nominal voltage: 12 V
 Rated capacity: 3.4 Ah (at the manufacturer’s specified rate)
 Battery chemistry: Sealed lead‑acid, valve‑regulated (VRLA)
 Rechargeable: yes
 Maintenance: maintenance‑free, no fluid refilling required
 Typical applications: standby/backup power, UPS, alarms, emergency lighting
How to use
Install the battery in the device or enclosure following the equipment manufacturer’s instructions and polarity markings. Use a compatible charger or the device’s built‑in charging circuit designed for sealed lead‑acid batteries; avoid overcharging or charging at incorrect voltages. Ensure correct ventilation and avoid sealing the battery in a completely airtight compartment. Periodically check terminals for secure connections and clean any corrosion if present. For storage, keep the battery charged and store at moderate temperatures to minimize capacity loss over time.
What to consider before purchase
 Verify the physical dimensions and terminal type fit the intended device or battery compartment
 Confirm the voltage and capacity meet the runtime and load requirements of your equipment
 Ensure your charger or UPS charging profile is compatible with sealed lead‑acid (VRLA) batteries
 Consider operating temperature range and storage conditions recommended for lead‑acid batteries
Usage recommendations
For reliable backup performance, keep the battery connected to a proper float or cyclic charger per the device specifications, perform periodic capacity checks in critical systems, and replace the battery according to the equipment manufacturer’s recommended service interval or when capacity noticeably declines.
