After the initial quote of £289.35 (GBP) from Keysight to replace the
battery, Keysight have now agreed to do it for £99. That's a lot more than
free, but at least it's a significant reduction from the original price

I had worked out that had I paid Keysight £289.35 to get the battery
replaced, plus another £140 for the calibration, the total was more than
60% of the cost of a brand new Keysight 34460A 6.5 digit meter.

I must admit, I have not done a detailed comparison between the 3457A,
34460A  and the more expensive 34461A 6.5 digit multimeters, but I have
decided to begrudgingly accept the £99 charge for the 3457A battery
