Sealed Lead Acid Battery ULTRACELL 12V/5AH-UL — 12V 5Ah rechargeable battery (sealed)

Sealed lead acid battery ULTRACELL 12V/5AH-UL is a 12-volt, 5 ampere-hour rechargeable battery designed for backup power in a variety of small to medium applications. The battery features a sealed, maintenance-free construction that supports flexible mounting positions and reduced self-discharge compared with flooded cells. It is compatible with standard 12V lead-acid chargers and is intended for use in alarm systems, UPS modules, emergency lighting, telecom devices and other equipment that requires a compact, reliable 12V power source.

Advantages

The sealed design eliminates the need for periodic electrolyte checks or topping up, providing maintenance-free operation. Its compact dimensions and standard terminal layout allow straightforward replacement of similar 12V batteries. Low self-discharge and stable output under typical discharge rates deliver reliable standby performance, while compatibility with common 12V charging profiles makes integration with existing chargers and systems simple.

Suitable for

• Uninterruptible power supplies (UPS) for small electronics
• Alarm and security systems
• Emergency and exit lighting
• Small telecom and network devices
• Mobility aids and portable equipment with 12V requirements

Key specifications

• Nominal voltage: 12 V
• Nominal capacity: 5 Ah (ampere-hours)
• Battery type: sealed lead-acid, maintenance-free
• Usable mounting: flexible orientations allowed
• Typical applications: standby/backup power, cyclic use where appropriate

How to use

Install the battery in the equipment compartment or holder provided, observing correct polarity for the positive and negative terminals. Use a charger or charging circuit designed for 12V sealed lead-acid batteries and follow the recommended charging voltage and current for a 5 Ah battery to avoid overcharging. For standby applications, keep the battery connected to the device’s charging circuit so it remains fully charged and ready for use. Replace the battery when capacity diminishes noticeably or when the device indicates end-of-life.

Usage recommendations

Store and operate the battery within manufacturer-recommended temperature ranges to maximise service life; avoid deep discharges when possible and recharge promptly after use. Dispose of the battery properly according to local regulations for lead-acid batteries and recycling facilities.
