These two complete battery assemblies were run downhole in the same conditions, for nearly the same length of time, with dramatically different results. As you can see, the assembly with BeCu components is badly pitted and ready for retirement. The other assembly has no BeCu components, instead using a combination of Nitronic-50 and our own proprietary material, SMS-167. It's already been sent out for another job. Which will you choose?
