When replacing capacitors should I look at higher or lower ripple current ratings?

When I tried to repair LG 29 inch CRT TV, I found that the ESR value of samyoung SMS capacitor(160v 2.2uf), which is very close to D1879 transistor, is 6 ohm.
Judging from above ESR Meter Table,I think It is necessary to replace this sms capacitor.So I visited local electronics shop,and I purchased 160v 2.2uf rubycon YK capacitor.
But when I browse through rubycon YK datasheet,I found that there is no ripple current rating for 160v 2.2uf specification. But On the contrary, I found 39 mA ripple current rating for 160v 2.2uf SMS capacitor.

I'd like to start out by thanking this forum for providing the info to be able to repair my 15 year old CP1500AVRLCD UPS. Here is all the info I gathered during my trouble-shooting and re-capping.
Like clockwork, I've had to replace the SLA batteries every 4 years. It was about that time and the UPS was acting like it needed new batteries... randomly shutting off with AC present, not being able to charge fully, and poor runtime when AC was removed. So, I replaced the batteries but noticed that it was not charging properly.
I decided to verify that the batteries were... -

Recently I purchased a Tektronix TDS1012, a 20 years old product for cheap and I thought it could be a nice opportunity for playing (i.e. recapping) and learn something in the process.
The power supply board is exactly the same from this post so I'll just steal it for now.

Howdy folks,
I have an Optiplex GX260 that blew a couple of those troublesome Nichicon HM series (ultra low ESR) electrolytic capacitors. Because said caps are obsolete, they are pretty much impossible to find on the market; I did find a listing for some but I believe they are counterfeit. I feel the easiest thing to do would be to replace all the blown caps with polymer ones. I am by no means an expert in electronics, and I've found a fair bit of conflicting information, so any guidance or confirmation would be greatly appreciated. While from a practical standpoint it's not worth... -
Hello everyone.
I'm having issues with my DJ mixer, and after taking it apart and checking everything out, it seems that I need to replace 2 rotary potentiometers for the filter, and that the PSU has some caps burned. Hopefully these 2 fixes will solve my issues.
The potentiometers I will just replace (hopefully the repairman I spoke with will indeed send me the spares, in case he doesn't, I'll update here if we can find a suitable replacement), but for the PSU caps I'd kindly ask you forum members, if anyone could help guide me in the right direction. I'm having difficulty...
