Lead Crystal / Silicon Dioxide Batteries (SiO2)

• No freezing. Higher temperature range with greater capacity than other batteries at low temperatures. -40C to +65C
• Zero maintenance. No off-gassing. No acid spills. 1 year shelf life without charging.
• Faster charging (.25C charge rate). 4 Hour charging vs. 7 Hours for lead acid.
• Approx. 1/3 of lithium ion cost.
• Long lasting up to 5 times longer than AGM batteries at 50% DoD (depth of discharge). Up to 7 x longer at 80% DoD. SiO2 batteries last to 16 years at 20% DoD.
• Can be discharged repeatedly to 100% DoD with full recovery of capacity.
