Questions about this item

Does the Estry 2028.2PP battery ship alone or with a charger included?

The listing shows only the single Ni-MH cell at 1.2V and 1800mAh; no charger is mentioned, so you will need to use your existing charger or buy one separately.

My device takes a Carrera 28.1 pack — will this Estry 2028.2PP replacement fit and work?

Yes, the supplier confirms compatibility with models 28.1, 2028.2, 28.2 and 28.3, matching the original voltage of 1.2V and capacity of 1800mAh.

What runtime can I expect from the 1800mAh rating once the cell is installed in my Carrera device?

At 1.2V the cell stores 2.16Wh; actual run time depends on your device's current draw, but the capacity matches the original specification for direct replacement.
