High-Capacity AGM VRLA SLA Batteries – 120Ah to 260Ah

If you need serious power, large-capacity sealed lead acid batteries are the ideal solution. Ranging from 120Ah to 260Ah, these AGM, VRLA, and SLA batteries are designed for demanding applications where reliability, deep cycling, and maintenance-free performance are essential.

Whether for off-grid systems, mobility, backup power, or industrial equipment, these batteries deliver stable energy and long service life—even under heavy use.

Common Uses for Large-Capacity SLA / AGM Batteries

These batteries are used across a wide variety of applications, thanks to their high output and rugged, low-maintenance design:

1. Solar & Off-Grid Power Systems

  • Ideal for storing energy in solar panel systems and off-grid setups
  • Used in battery banks for homes, cabins, sheds, and portable solar systems
  • Reliable for both daily cycling and emergency power storage

2. Backup Power & UPS Systems

  • Used in uninterruptible power supplies (UPS) for homes, data centres, and commercial buildings
  • Provides emergency power for critical systems like security alarms, routers, lighting, and medical devices

3. Electric Vehicles & Mobility Equipment

  • High-capacity options suitable for electric scooters, mobility aids, and transport carts
  • Offers longer runtime for heavier equipment or extended distances

4. Recreational Vehicles & Marine Use

  • Commonly installed in caravans, motorhomes, campervans, and boats
  • Powers 12V appliances, lighting, and inverter systems when off-grid

5. Industrial & Commercial Equipment

  • Used in floor scrubbers, scissor lifts, pallet trucks, and other battery-powered machinery
  • Provides long operating times and resists vibration in rough environments

6. Telecom & IT Infrastructure

  • Supports backup and standby power for telecom towers and network systems
  • Maintains critical uptime for servers, routers, and communication equipment
