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.
8-12 year service life, based on up to 30-50% daily discharge
Can be discharged repeatedly to 100% DoD with full recovery of capacity.
Can be used in SERIES or PARALLEL or a combination of SERIES and PARALLEL to make 12V, 24V, 48 or 96V banks.
