This document provides specifications for a CP1290 12V 9Ah lead-acid battery. The battery uses absorbed glass mat technology, has a sealed construction, and is maintenance-free. It has a nominal voltage of 12V, capacity of 9Ah, and dimensions of 151mm x 65mm x 94mm. The document outlines the battery's components, general features, performance characteristics, discharge curves, and charging characteristics.

1. CP1290 12V 9Ah(20hr)
The rechargeable batteries are lead-lead dioxide systems. The dilute sulfuric acid
electrolyte is absorbed by separators and plates and thus immobilized. Should the
battery be accidentally overcharged producing hydrogen and oxygen, special one-
way valves allow the gases to escape thus avoiding excessive pressure build-up.
Otherwise, the battery is completely sealed and is, therefore, maintenance-free,
leak proof and usable in any position.
