  • EFSN
  • Terminal F4

Why you need to change your battery today:

  • Suitable for tough weather conditions with stable performance under extreme cold (down to -40C) or dry heat (up to 65 degrees Celsius)
  • 2 years Warranty
  • 12-month shelf life without needing to refresh the battery
  • No Sulphation
  • 8-12 year service life, based on up to 30-50% daily discharge
  • Long lasting up to five times longer than AGM batteries at 50% DoD (depth of discharge)
  • Full recovery after a deep discharge
  • High cycle life – 2800 Cycles at 50% DoD
  • Environmentally friendly
  • Safe to transport by air
  • No leakage and very low gassing compared to Lead Acid Batteries
  • 99% Recyclable
  • Huge range of sizes to fit every application, from scooters, wheelchairs, lifts and uninteruptable power supply systems to RVs, campers, fishing boats to large solar energy storage banks.

The SiO2 Battery is a high performance battery comparable to Lithium-Ion in both depth of discharge and cycling capabilities for a third of its price. It even out-competes many similar Li-Ion batteries in longevity when subjected to the same discharge, temperatures, and partial state of charge abuse.SiO2 Cycle Life Chart

This means the SiO2 Battery boasts a fantastically low cost per Kilowatt-Hour over its entire lifetime. Each cent gives users more watts for longer to provide the best long-term solution with short-term costs. It even has a longer shelf life, only discharging less than 1.6% of its power over a month.

The silicon dioxide battery lasts 10-15 years, depending on use, thanks to its unique chemistry. The pH neutral electrolyte prevents sulphation and does not corrode the internal components.photo comparing SiO2 and lead acid battery

Cold Weather Champion

The SiO2 Battery’s effectiveness in extreme temperatures stands out against all competition. The cold-resistant technology was developed for use in machinery up North and performs far better than any other battery technology on the market.

These batteries provide 40% more power than lead-acid battery at temperatures as low as -40 °C/F.

These batteries also offer superior performance in Extreme heat and are rated for +65C / 149Fchart showing temperature and discharge capacity

Safer, Easier, and Greener
The Ultra Long Life battery is lighter weight than other types of Lead-Acid batteries and is easier to transport and install since it can be placed on any side or orientation.

These batteries are up to 99% recyclable and an excellent battery for environmentally-conscious users wanting to minimize the carbon footprint of their solar array.

These deep cycle batteries require no maintenance and are non-gassing. This makes them safer in high temperatures or remote battery banks and backup power storage. It is safe for air travel and can be used as marine batteries.

Settings for your SiO2 battery if you are choosing custom programming on your charge controller:

Equalizing Voltage -> 14.6 or Shut off this function if available
Boost Voltage -> 14.6
Floating Charge Voltage -> 13.6
Over-discharge Return Voltage -> 12.7
Over-discharge Voltage -> 11.8
