A:AnswerI have a set of Panasonic KX-TGA402 and the batteries work as expected. Matching battery voltages for phone, with Higher M-amp ratings on batteries typically ensure longer run times in standby & active talk time.
Pricing was reasonable and less than OEM products.
A:AnswerThank you for reaching out! In regards to your question, kindly be informed that this model of batteries, HHR-4DPA, is compatible with the cordless handsets from the KX-TG7871 system.
A:AnswerI'm not sure Beck. But what I did was go to Panasonic's website and enter in the model number of the phone and it will show you what batteries to use.
