You may think so, but I've always hated having trailing leads going from a board I'm working on... you turn the board over and the wretched things drop off.
Charging a small cap is hardly complicated...
Each to their own, but if the leads drop off, surely you're using the wrong connectors
And if you're happy to tack on a capacitor, why not tack on a couple of leads?
With a bench power supply, the metering gives you the reassurance of knowing what voltage is applied. With a capacitor, the charge could disappear and you wouldn't know.
Ultimately, any method has pros and cons - it's certainly good to have a range of options on the table...
As far as I can tell from the manual, the battery is only there to store user stuff? So at least it's not calibration data, making it a "low risk" change. The last battery I changed was the one in my HP 3568A - that was somewhat more critical, as re-calibrating that would have been a pain, to say the least. Luckily all went well. Amusingly, the old battery is still perfect, many years on - not bad for a 30 year old battery! Next time it'll be the one in my HP 3314A, but that only stores user data, so I'll only be changing it to mitigate the risk of leakage. Not urgent...
