Compatibility and limits

This pack fits the long list of model numbers and part numbers shown in the specifications, covering devices such as 6538-1, EY3652DA, EY503B, EY6220 and many others. It will not work for equipment that requires a different voltage, a different chemistry or a different physical footprint. Buyers needing higher capacity, lithium-ion chemistry or an alternative form factor must look elsewhere.

Voltage and capacity check

The single figure that decides fitment is the 2.4 V 3000 mAh rating; the device must be designed for exactly that voltage and capacity. Verify the original battery label before ordering to avoid mismatched power delivery.
