ocket Nova N120 (120Ah) Battery Specifications (Typical)

This document provides the expected specifications for a Rocket N120 lead-acid battery. This type of battery is generally used for deep cycle, backup power, or heavy-duty starting applications.

General Information

Feature	Specification	Notes
Model	N120 / Nova Rocket	Common designation for 120Ah battery.
Chemistry	Lead-Acid (Wet Cell, MF/SMF)	MF (Maintenance-Free) or SMF (Sealed Maintenance-Free) is typical.
Nominal Voltage	$12\text{V}$	Standard for automotive and inverter batteries.
Rated Capacity ($\text{Ah}$)	$120\text{Ah}$	Based on a $20\text{hr}$ discharge rate.
Approximate Weight	$28-35\text{ kg}$	Weight varies based on internal plate structure.
