The battery has been disconnected for around 11 hrs now:
13.13 VDC
13.13 VDC
AT 13.13V I bet you still have some surface charge.
With my Fluke 117 I measured parasitic current.
Initial: 300mA
3 min: 20-80mA fluctuating
Hmmmmmm

At first it read 0.000A. Fuse was somehow blown. Luckily I had a spare.
The parasitic current on my 2005 Subaru fluctuates from 44-58mA, in synchronicity with the flashing security light on my dash.
If the covers are under stickers it is a 'maintenance free' battery and unlikely to be low on water, as their gassing voltage is higher.
Maintenance free flooded are unlikely to ever need rewatering before they die form age/sulfation in non cyclic usage, and are not a good battery if deep cycle duty is intended.
I have a 8 year old sulfated Exide Edge AGM battery that I recently removed from service. I charged it yesterday with a CTEK.
Today I gave it a 400A load for 15 seconds. 2 hours later it measured 12.95V at a battery temperature of 22degF.
Battery voltage can sometimes be misleading.
I can't think of any, as long as you give it good powered-up and powered-down times. Eg not just a second here and there. Make your ammeter connection as sturdy as possible.Is there any problem with doing multiple parasitic drain tests? I mean repeatedly connecting and disconnecting the battery?

Huh. Our CRV has a bad CD changer (supposedly, never tried it, don't have a reason to), and it won't hold a charge for more than a few days. Been looking for a reason to yank it, maybe it's time...

In this article I describe two parasitic drain case studies—one of my first, from more than 40 years ago, and my most recent. A technician’s nightmare is diagnosing an intermittent high parasitic drain, as were both of these cases. Neither study involves hybrid or electric vehicles. By parasitic...www.motor.com

I'm planning on Wallyworld's finest. Just need FM, Bluetooth and aux input.
