Smart Car Battery Charger

How would you know the CCA of a regular UPS battery if the label says Ah ratings only? VRLA Gel and AGM types on -48VDC system also have Ah ratings but not CCA? I've read the manual online and it says from 100CCA 5increments to 2000CCA, so if I'm going to test a 100Ah VRLA, what CCA should i choose from the menu? I guess test will only be accurate if CCA is advertised by the battery manufacturer as the tester compare CCA values to get the SOH.

All this time, I haven't actually used the tester on UPS batteries as I didn't have any SLA batteries lying around. But as I looked at the Micro 200 spec sheet, I realized that, although, it is designed for 12-24V lead acid battery configurations, it can only measure batteries that are between 30-200 Ah in capacity... which is car battery territory.

Most commodity compact UPSes use 12V | 4, 7 or 12 Ah batteries, which is way below what the Micro 200 can accurately measure. For that, you could opt to exchange it for the Micro 30 instead. The Micro 30 can measure 12V SLA batteries in the 3-30 Ah range.

So, I'm just finding this out right now, too. Sucks to know that I can't use the Micro 200 on any of my Yuasa NP7-12 batteries that are currently in service. But knowing what I know now, I'll be buying a Micro 30 to test UPS batteries and keep the Micro 200 for batteries larger than 30 Ah.

I should've left a disclaimer; Caveat emptor. Sorry bro.
