First of all try and clean those surface as good as possible. The tape needs to be on flat surface for good results. If you can , I would take batteries of bezel clean all that area, rearrange batteries in line for better mounting space.
Use OUTDOOR 3M double sided tape. It is grey with red cover. It's the best. And thin too (max 1mm thickness). h..p://www.scotchbrand.com/wps/portal/3M/en_US/ScotchBrand/Scotch/Products/Catalog/~/Scotch-Outdoor-Mounting-Tape?N=6604493&rt=rud
