EVI 9Ah 12V Lead-Acid Battery
EVI 9Ah 12V Lead-Acid Battery – EVIA9-12
The EVI EVIA9-12 is a specialized 12V 9Ah Sealed Lead-Acid (SLA) battery, most commonly used as a high-performance replacement for UPS systems (like APC, Mercury, or Mecer), security panels, and emergency lighting.
Since it shares the same physical footprint as standard 7Ah and 8Ah batteries, it is often purchased as a “capacity upgrade” to provide 20–30% more backup runtime in the same space.

Performance & Charging
-
Design Life: 3–5 years in standby (float) service.
-
Cycle Life: Robust enough for ~260 full discharge cycles or over 600 cycles at 50% depth of discharge.
-
Float Charge Voltage: $13.6\text{V}$ to $13.8\text{V}$ (ideal for UPS standby).
-
Cycle Charge Voltage: $14.4\text{V}$ to $15.0\text{V}$ (for active use like scooters or portable sprayers).
-
Max Charge Current: Recommended maximum of 2.7A.
Key Advantages
-
Non-Spillable: Can be mounted on its side or end without leaking (though upside-down is not recommended during charging).
-
Maintenance-Free: Never requires water top-ups; the gas recombination technology handles internal pressure.
-
High Discharge Rate: Designed to handle the sudden, heavy power draws required by UPS units during a blackout.
Common Replacements
The EVIA9-12 is a direct drop-in replacement for any 12V 7Ah, 7.2Ah, 7.5Ah, or 8Ah battery of the same size. If your current battery says 12V 7.2Ah and has dimensions of roughly 151 x 65 x 94 mm, this EVI 9Ah model will fit perfectly and last longer.
