Why choose it

Gel technology immobilizes the electrolyte, making this battery leak-proof and safe for indoor use in any orientation. It withstands deep discharges better than standard AGM, holds its charge during long idle periods, and resists vibration and shock. The ABS case is rugged and flame-retardant, while the F2 terminals accept standard push-on connectors for quick installation.

Ideal use cases

• Uninterruptible power supplies (UPS) for computers, servers, and network equipment
• Burglar and fire alarm systems
• Solar power storage for off-grid lighting and small appliances
• Emergency lighting and exit signs
• Electric scooters, wheelchairs, and other mobility devices
• Portable medical equipment and instrumentation

Good to know

For maximum service life, recharge the battery promptly after each discharge and store it in a cool, dry place. At 25°C, self-discharge is minimal, but a top-up charge every 6 months is recommended if stored for extended periods. Always use a charger with voltage settings within the specified range to avoid overcharging. This battery is not intended for automotive starting applications.
