What it means that the SD-45.1T is lead-acid
Inside, the SD-45.1T is classic lead-acid: liquid electrolyte and lead plates. If the SD-45.1T is left discharged for weeks it sulphates: a maintenance charger prevents this.
What to look at before buying the SD-45.1T
- If your car has Start-Stop, the SD-45.1T is not the right one: it needs an EFB or an AGM.
- Check the EN amps on your battery: if it says 300 A or less, the SD-45.1T covers your engine.
- Capacity of the SD-45.1T: 45 Ah; the same as your current battery or slightly more is fine.
- Polarity of the SD-45.1T: positive terminal on the left (if yours has it on the other side, the cables will not reach).
- The SD-45.1T needs 219 × 135 × 225 mm of space: measure it with the hold-down clamp in place.

Can the Kronobat SD-45.1T be used in a car with Start-Stop?

10.8 kg, with 45 Ah of capacity. For reference, the Kronobat PB-45.1F (45 Ah) weighs 11.7 kg.
Which battery is equivalent to the Kronobat SD-45.1T?
