ExpertPower 12V 18Ah AGM Sealed Lead Acid Battery — NB Terminals, Maintenance-Free Backup

This compact, valve-regulated battery delivers steady, slow-discharge power for standby and low-drain applications. Sized at 7.13" x 3.03" x 6.57" (181 x 77 x 167 mm) and weighing about 5.20 kg (11.46 lb), it uses NB (nut-and-bolt) terminals and fits many UPS units, alarm panels, small solar systems, mobility devices, and other 12V setups. It replaces common 12V 18Ah types such as UB12180, NP18-12, NP20-12, and others.

How much runtime and lifespan can I expect from this 12V 18Ah battery?

The EXP12180 is engineered for standby and moderate-discharge use rather than high-rate loads. In standby service the battery typically offers a 3–5 year service life when stored and charged correctly; actual runtime depends on the connected device's draw.

• Rated capacity: 18 amp-hours at 20-hour rate (20HR).
• Best for low to moderate continuous draw and intermittent backup cycles.
• Standby life estimate: 3–5 years under recommended float charging and room-temperature storage.

What charging setup and maintenance does the EXP12180 need?

Use a 12V smart charger and avoid deep discharges to protect capacity and life. Follow the manufacturer-recommended voltages for consistent, safe charging and store the battery fully charged if not in use.

• Charge cycle voltage: 14.6–14.8 V @ 25 °C.
• Float voltage: 13.7–13.9 V @ 25 °C; recommended charge current: ~2–5 A.
• Maintenance-free AGM design: no watering, sealed and spill-proof for enclosed installations.

Will this battery physically and electrically fit my equipment?

Measure tray clearance, lead length and connector type before installation—this battery uses NB terminals (nut-and-bolt) that require compatible connectors or adapters. Its compact footprint makes it suitable for many UPS cabinets, alarm enclosures and small off-grid systems.

• Dimensions: 7.13" L x 3.03" W x 6.57" H (181 x 77 x 167 mm).
• Weight: approximately 5.20 kg (11.46 lb); check mounting limitations.
• Replaces popular 12V 18Ah types: UB12180, PS-12180, NP18-12, NP20-12, and others.

How safe and durable is this sealed lead-acid battery?

The AGM construction keeps electrolyte immobilized for spill-proof, indoor-safe installations and reduced maintenance. Proper charging and avoiding deep discharges will extend service life and maintain reliable performance in standby applications.

• Sealed, valve-regulated design minimizes leakage and service needs.
• AGM plates resist vibration, useful for portable and mobile setups.
• Store at full charge and recharge periodically to prevent capacity loss.

Who is this for: The ExpertPower EXP12180 suits technicians and homeowners needing a compact, maintenance-free 12V battery for UPS replacements, alarm systems, small solar arrays, mobility devices, emergency lighting, or other low-to-moderate draw applications. Choose this battery when you need a drop-in 18Ah AGM option with NB terminals and predictable float-charge behavior; confirm physical fit and terminal compatibility before ordering.
