@@Shield-pg8xiI have a DW-5600E from 2013 and the battery is replaced only once in 2019. The second battery is working fine. I did replace the bezel covering. Greetings from India. I respect the technological advancements of Japan, but these days it is not as good as in the 1980s. Especially some Japan made ballpoint pens of 2020s do not work as well. What do you think? You may have to translate!
