Can I replace my lead acid car battery with a sodium ion battery?

Yes. SaltyCells sodium ion batteries are drop in replacements. Same 12V system, same terminals, charged by your existing alternator. Confirm the physical dimensions and terminal layout match your battery tray before ordering.

How long does a sodium ion car battery last?

SaltyCells batteries are rated for 3,000 or more cycles at 60 percent depth of discharge. For a typical daily driven car that translates to roughly 8 to 10 years, compared with 2 to 4 years for lead acid. Warranty is 5 years.

Do sodium ion car batteries work in Australian summer heat?

Yes, and this is where they shine. The cells are discharge rated to 70 degrees Celsius, well beyond typical under bonnet temperatures. Heat is the main reason lead acid batteries die early in Australia, so the advantage compounds over time.

Are sodium ion car batteries safe?

Yes. Sodium ion chemistry is more thermally stable than the lithium cobalt chemistries people associate with battery fires, and every SaltyCells battery has a built in BMS protecting against overcharge, over discharge and short circuits. They can also be safely discharged to 0V for storage and transport.

Do I need a special charger for a sodium ion car battery?

For normal driving, no. Your alternator charges the battery as usual. If you use a bench charger, one with a lithium or adjustable profile is ideal.
