Lead-Acid Battery Y4-6

Yuasa Y4-6 Lead Acid Battery – Performance and reliability in a compact format

The Yuasa Y4-6 is a 6-volt, 4-amp-hour sealed lead-acid battery designed to provide a constant and secure power supply. Thanks to its valve-regulated lead-acid (VRLA) technology, it is maintenance-free and can be used in any position without risk of leakage. This original Yuasa model stands out for its reliability, low self-discharge and resistance to repeated charge and discharge cycles.

Weighing only 0.651 kg and featuring a compact size (70 mm x 47 mm x 105.5 mm), the Y4-6 is ideal for devices requiring a stand-alone power supply in a limited space. It is commonly found in backup systems (UPS, alarms), signalling devices, motorised toys, portable medical devices and light industrial equipment.

Its robust casing provides good protection against shocks and vibrations, and its design ensures a long service life, even under intensive use.
