Is a sodium ion battery a straight swap for my existing lead acid battery?

Yes, SaltyCells batteries are built to the same case sizes and terminal layouts as the lead acid batteries they replace, so no wiring or tray changes are needed in most vehicles. Check the size guide or installation guide to confirm before ordering.

How much longer does a sodium ion battery actually last?

SaltyCells batteries are rated for 3,000+ cycles at 60 percent depth of discharge, against roughly 300 to 500 cycles for typical lead acid. In practice that means one sodium ion battery can outlast several lead acid replacements over the same period of vehicle ownership.

Does sodium ion perform better in Australian heat?

Sodium ion chemistry does not suffer the same accelerated plate degradation that heat causes in lead acid batteries, and SaltyCells batteries carry a discharge rating down to minus 30 degrees Celsius and up to 70 degrees Celsius.

Is the upfront cost worth it if I am only keeping my car another year or two?

Probably not on cost alone. The upgrade makes the strongest financial sense over a three year or longer ownership horizon, where avoiding two or three lead acid replacements outweighs the higher initial price.

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

No. SaltyCells batteries are designed to charge from a standard vehicle alternator and standard trickle chargers, with no special BMS or charging profile required.
