A rather veteran Braun 7505 shaver (circa 10 years), the Ni-Mh batteries needed a refresh and since I did not see any youtube available on this type of shaver, I decided to tape and post the replacement process. My apologies for the vertical orientation, I just noticed that after the fact... Normally I do better. Attention - The batteries must be 1700ma/hr or less, otherwise the shaver cannot charge them properly. It is tempting to put stronger ones, but do not.
Update 4 weeks later - On one charge the new batteries worked for over 3 weeks. No doubt that was needed and gave life to the shaver for a few more years.
