Not to mention it's a bad value? An NVRAM costs $39.95. Ok. A remote battery holder and 30 years worth of batteries costs ~$21-$23...
Thank you all who came here to belittle, berate, or highjack the thread when I'm asking a simple question about how to wire in a remote battery holder.
Quoted from pinballkyle:Nvram is a great solution but it does have its downfalls too.
The fit of the stern socket can be quite loose for the nvram and can cause the memory to be occasionally erased due to a loose fit. This has happened on two of my sterns on location.
Technically it's plug and play but if you want it to work perfectly for years, the old socket should be desoldered and the included socket should be installed. This is what I'm doing now.
