Product Features

High-Performance SMF Design

Valve-Regulated Lead-Acid (VRLA) technology with Absorbent Glass Mat (AGM) ensures spill-proof, maintenance-free operation and high-efficiency energy discharge.

Wide Application Range

Ideal for home and office UPS systems, CCTV security systems, emergency lighting, solar standby power, and small electric vehicles like scooters and toys.

Durable and Compact

Constructed with flame-retardant ABS plastic, the LW 7AH is lightweight (2.25–2.4 kg) and compact (151 × 65 × 94 mm), making it easy to install in tight spaces.

Efficient Charging

Supports cycle use charging at 14.4V–15.0V and standby/float charging at 13.5V–13.8V, maintaining optimal capacity and long battery life.

High Discharge Capability

Can handle short bursts up to 112A for 5 seconds, providing reliable performance during high-load events.

Long Service Life

Designed for 3–5 years of standby operation with over 500 cycles at 50% depth of discharge, offering dependable performance over time.

Low Self-Discharge

Maintains charge with less than 3% self-discharge per month at 25°C, ideal for backup applications and storage.

Secure Terminal Options

Available with F1 (4.75 mm) or F2 (6.35 mm) Faston Tab terminals for secure and easy connection to devices.
