12V 15Ah GEL Deep Cycle Battery TED ® M5 151×98×95 mm

Sealed 12V 15Ah GEL deep cycle battery by TED ®, model M5, with compact dimensions 151×98×95 mm. Engineered for repeated deep discharge and recharge cycles, this maintenance-free GEL battery uses a gelled electrolyte to reduce leakage risk and enable flexible mounting orientations. It provides stable voltage output and consistent capacity over prolonged standby or cycling use, making it suitable where reliable long-term energy storage is required.

Advantages

The GEL construction offers enhanced vibration resistance and minimal water loss compared with flooded batteries, reducing maintenance requirements and allowing use in enclosed or confined spaces. Its sealed design prevents electrolyte spillage and makes handling safer in portable and fixed installations. The battery’s deep cycle capability supports frequent discharge/recharge sequences while preserving capacity and cycle life. Compact dimensions and a moderate weight simplify installation in UPS systems, renewable energy setups, electric mobility devices and backup power cabinets.

Suitable for

• Uninterruptible power supplies (UPS) for home or small office equipment
• Solar energy storage in small off-grid or hybrid systems
• Mobility devices such as electric scooters, wheelchairs and mobility aids

How to use

Install the battery in a well-ventilated, dry location with stable ambient temperature and secure mounting to prevent movement. Connect to the application following correct polarity and recommended cable cross-sections to minimize voltage drop. For initial commissioning, charge the battery according to the charger manufacturer’s specification for GEL deep-cycle batteries, using appropriate charging voltage and current limits. Avoid deep discharge beyond recommended depth of discharge to maximize cycle life and follow monitoring practices for state of charge in cyclic applications. When replacing an existing battery, ensure compatibility with system voltage and capacity requirements.

Usage recommendations

For optimal life and performance, use a charger with GEL-specific charge profile and temperature compensation where applicable. Store batteries at a partial state of charge in a cool, dry place and recharge every few months if not in use. Avoid prolonged exposure to high temperatures and prevent over-discharge to preserve capacity and cycle longevity.
