No, because you know that some components will fail and you will even have a rough idea of how reliable they are.
If the same transistor failed more than once, then you would start looking into what (if any) is the underlying cause.
If a power supply failed, it would be replaced and, if it failed again, someone would be looking to see what caused the failures.
With batteries, I have never experienced catastrophic failures that were not caused by external action such as someone connecting it up wrong, dropping their spanner on it etc.
There are batteries driving radio sites in the Middle East that I installed nearly 20 years ago. None have ever decided to burst into flames.
On the other hand, a new transmitter/receiver was being introduced on a massive scale by my former employers and they kept failing. One day, a meeting was held to discuss the fix the development people had found and we (about 15 people in UK & US) were asked to agree to support the fix. I refused on the grounds that it was my team that would be lumbered with constant calls from irate customers and short notice trips to Holland, South Korea and the Middle East. When the development people admitted they seemed to have stumbled on something that seems to stop the fault, yet they did not know the cause of the fault, they had to go away and do the job properly. A month later, they had found the 'real' fault and re-designed their fix. Some of the development team later told me they were glad I had stopped the roll out of this fix and forced them to find the root cause. Saved the company millions in support costs and penalties.
