Technical Questions

Backup time depends on battery capacity (Ah) and connected load (Watts).

Example:
  • 150Ah battery with 600W load: ~3-4 hours backup
  • 200Ah battery with 600W load: ~5-6 hours backup
  • 150Ah battery with 300W load: ~6-8 hours backup
Contact us for precise backup calculations based on your requirements.

Yes! Preston batteries are compatible with all major inverter brands including Luminous, Microtek, Su-Kam, Exide, V-Guard, and others. Just ensure the inverter voltage rating matches the battery (12V, 24V, 48V, etc.).

Most Preston inverter batteries are low-maintenance or zero-maintenance:
  • Lithium Batteries: Completely sealed, zero maintenance
  • Tubular Batteries: Water topping required every 6-12 months (very minimal)
  • SMF (Sealed Maintenance Free): No water topping ever required

Tubular Batteries (Recommended):
  • Longer life (5-7 years)
  • Better deep discharge recovery
  • More expensive but better value
Flat Plate Batteries:
  • Lower initial cost
  • Shorter life (2-3 years)
  • Suitable for infrequent power cuts
