Skytronic 656.819 - 12V 5Ah Sealed Lead Acid Battery (Maintenance-Free)

Skytronic 656.819 - 12V 5Ah Sealed Lead Acid Battery (Maintenance-Free)

The Skytronic 656.819 is a 12V 5Ah sealed lead acid rechargeable battery designed as a universal replacement for security systems, UPS, emergency lighting and other 12V electronic equipment. Its sealed, maintenance-free construction offers very low self-discharge and is leak-proof , ensuring stable operation in both float (stand-by) and moderate duty cycles. With a compact size of 90 x 70 x 101 mm (L x W x H) and 1.55 kg , it fits most standard 12V/5Ah battery compartments.

Main features

• Voltage/capacity: 12 V – 5 Ah.
• Technology: Sealed lead-acid (VRLA/SLA) battery, maintenance-free and spill-proof.
• Self-discharge: very low, suitable for long-term standby use.
• Dimensions (L × W × H): 90 × 70 × 101 mm.
• Weight: 1.55 kg.
• Compatibility: Common replacement for 12V/5Ah UPS, alarms, CCTV, access control and emergency lighting.

Frequently Asked Questions

What charging voltages should I use?
For 12 V VRLA batteries, typical reference ranges are 13.5–13.8 V in float and 14.4–15.0 V in cyclic charging (20–25 °C), with temperature compensation and initial current limiting.

What type of terminal do you use (F1/F2)?
May vary depending on the batch or destination device. Please verify the Faston type required by your device (4.8 mm F1 or 6.3 mm F2) before purchasing.

Recommendations for use and safety

• Respect polarity and avoid short circuits.
• Use chargers specifically designed for 12V VRLA batteries and follow the voltages indicated.
• Do not expose to extreme temperatures or heat sources; store in a cool place and recharge periodically when not in use.
• Recycle the spent battery according to local regulations.
