EVI 9Ah 12V Lead-Acid Battery (EVIA9-12)

The EVI 9Ah 12V Lead-Acid Battery (EVIA9-12) is a high-quality, maintenance-free AGM (Absorbent Glass Mat) battery engineered to provide dependable backup power for a wide range of critical systems. With a reliable 9Ah capacity and 12V output, it is the ideal direct replacement or spare battery for small to medium UPS systems (800VA–3000VA), security alarms, emergency lighting, and off-grid solar applications. Featuring superior deep-cycle recovery, low self-discharge, and a robust valve-regulated design, this battery ensures your essential devices remain operational during power outages, offering peace of mind for homes, offices, and commercial installations across Kenya.

Product Features

AGM Technology for Maintenance-Free Reliability

This battery utilizes advanced Absorbent Glass Mat (AGM) technology, where the electrolyte is suspended in a fiberglass mat. This design makes it completely sealed, leak-proof, and maintenance-free, allowing for safe operation in any orientation. It provides excellent deep-discharge recovery and is ideal for both standby and cyclic applications.

High Capacity for Extended Runtime

With a rated capacity of 9Ah at the 20-hour discharge rate, this battery offers extended backup time compared to standard 7Ah models. This makes it a perfect upgrade or replacement for UPS systems, providing valuable additional minutes of runtime for computers, network equipment, and other critical loads during blackouts.

Robust Cycle Life and Deep Discharge Performance

Engineered for durability, the battery delivers a long cycle life—over 260 cycles at 100% depth of discharge (DOD) and more than 650 cycles at 50% DOD. Its construction with high-purity lead-calcium grids minimizes water loss and maximizes service life, making it reliable for frequent use in solar and security applications.

Low Self-Discharge for Long Shelf Life

The battery features a very low self-discharge rate of less than 3% per month at 25°C. This ensures it retains its charge over long periods of storage, keeping it ready for immediate use in standby applications like alarm panels and emergency lighting, even after months of inactivity.

Standardized Dimensions and Terminals

Designed with universal compatibility in mind, it shares the same footprint (151mm L x 65mm W x 94mm H) as common 7Ah and 8Ah batteries, allowing for a direct, drop-in capacity upgrade. It is equipped with standard Faston F2 (6.35mm) terminals for easy and secure connection to a wide variety of devices.

Safe and Certified Construction

The battery is housed in a flame-retardant ABS case (UL94 V-0 rated) and features a safety valve to prevent pressure build-up. It is certified CE, ISO 9001, and ISO 14001, with components recognized by UL. It is also IATA A67 approved for safe, non-hazardous transport by air and road.

Wide Operating Temperature Range

Built to perform in diverse environments, it can operate in discharge temperatures from -20°C to +55°C and charge temperatures from 0°C to +45°C. This resilience makes it suitable for both indoor and protected outdoor installations across various climates.
