Last year I went down to Keysight for a course, and got a tour of their cal
labs. I spoke to the person showing us around about the 3457A battery. He
said if the battery was less than £35 or so, it could be replaced free of
charge when the instrument was calibrated.
So despite my 3457A's battery must be on its last legs, I decided not to
bother replacing it, as I thought Keysight would do it free. The other more
serious reason is that I can't seem to find a suitable battery in the UK.
This from Mouser
The Panasonic BR-2/3AE5SPN
looks like it will do the job, and is less than $6 in the USA, but I can't
get one in the UK.
Anyway, my meter was sent to Keysight for a technical evaluation, and today
I received a quote
* Keysight calibration with uncertainties £140 (GBP)
* Repair (time and material) £289.35 (GBP)
* Total £429.
All + 20% VAT
So far from being free, they now want a serious amount of money to replace
the battery! It's more than a third of the cost of a brand new 6.5 digit
meter, with the complete battery and calibration costing more than 50% of
the price of a new 6.5 digit meter.
With eBay being a counterfeiters paradise, I will not buy a battery from
there. None of the UK companies I find have something that looks suitable.
I might try to find someone in the USA who will post me one by surface
mail. That should avoid all the problems with air transport of lithium
