When do you need an AGM battery?
When the vehicle or equipment manufacturer specifies AGM — typically advanced start-stop, regenerative braking or high electrical loads. If AGM is fitted from the factory, replace it with AGM; fitting EFB or flooded is a downgrade.
Charging
Use a charger with an AGM mode; overcharging and heat shorten AGM life. Never add water.
Battery registration
Many modern vehicles with battery monitoring must be told that a new battery was installed (registration/coding with a diagnostic tool) so the charging strategy adapts.
Reading CCA
CCA is measured under different standards (SAE, EN, JIS). Only compare CCA values measured under the same standard.

Listed because the manufacturer’s data matches this category (type or technology). Being listed does not mean the battery suits your system — check its datasheet.
Frequently asked questions
Can I replace AGM with EFB?
No, if the vehicle came with AGM. EFB has lower cycling ability in partial state of charge. The reverse (EFB → AGM) is generally an upgrade, subject to the vehicle manufacturer's guidance.
Is spiral-wound AGM different?
Spiral-wound cells are an AGM construction with rolled plates. Electrically they are still AGM lead-acid; compare their datasheets like any other battery.
