Oral B Genius 9000 replace battery start to finish

Oral B Genius 9000 replace battery start to finish, a couple of tips for taking it apart, what battery to use, where I bought the battery.
I calculated the brush had been used for about 2.5 years and 64 hours, not a lot for a brush that cost around AUD $360 and Oral-B say the toothbrush should last 3-5 years.
I would not spend that type of money on a brush like that in the future. Repair cost around AuD$10.
