Yuasa Yucel 6V 1.2Ah SLA (Y1.2-6)

The Yuasa Yucel Y1.2‑6 is a compact, rechargeable 6‑volt sealed lead acid (SLA) battery designed for reliable backup and low‑power applications.

Overview

This model belongs to Yuasa’s Yucel range of valve‑regulated lead‑acid (VRLA) batteries, meaning it is fully sealed and maintenance‑free. It uses AGM (Absorbed Glass Mat) technology, where the electrolyte is absorbed into glass fibre separators—so there is no free liquid acid. 

Key specifications

• Nominal voltage: 6V 
• Capacity: 1.2Ah (20‑hour rate) 
• Dimensions: approx. 97 × 24 × 51.5 mm
• Weight: ~0.28 kg (280 g) 
• Terminal type: Faston/tab (quick‑connect) 
• Design life: typically 3–5 years under normal standby use 

Features

• Maintenance‑free design: sealed construction eliminates the need for topping up electrolyte. 
• Valve‑regulated (VRLA): built‑in safety valves allow controlled gas release while keeping the battery sealed. 
• AGM technology: improves reliability, reduces leakage risk, and enables efficient charge/discharge performance. 
• Flexible installation: can be used in most orientations (except permanently inverted). 
• Good recovery from deep discharge and stable standby performance. 

Typical applications

The Y1.2‑6 is widely used in low‑power and standby systems, such as:

• Burglar and fire alarm systems
• Emergency lighting units
• Backup power supplies (UPS)
• Medical and telecom devices
• Small electronic equipment or toys
