A savvy battery expert may save a useful piece of testing equipment — such as meters, scan tools and oscilloscopes — from premature extinction by creating an effective replacement battery for it.
Based on my field experience, some managers and technicians do not consider battery life, cost and availability when purchasing a tester of some kind.
Of course, batteries fail at one point or another in the life of the equipment, but whenever a battery does fail, the cost of replacement may startle the owner of the tester, meter, etc.
Incredibly — not to mention sadly — a diagnostic device may collect dust because its owner postpones purchasing a new battery for it.
In fact, some techs I know have acquired an oscilloscope or tester dirt cheap solely because a discouraged owner balked at the cost of replacing its battery.
Remember that a local specialist such as Batteries Plus Bulbs may be able to create a direct-fit replacement battery for you that equals or exceeds the electrical capacity of the original one.
Although I was aware of this company, I didn't know that its techs could customize batteries for various applications.
A shop foreman I know very well began sourcing replacement oscilloscope batteries from the neighborhood Batteries Plus store. Based on his recommendation, I began doing the same thing more than 10 years ago.
