Amp Hour counting with the OBDIIC&C Gauge

The recommended lead does not end in a serial plug it ends in a USB one. It has the serial/usb converter built in.
I just clicked the link in your quote of my post and it took me straight to the right one.

Voila! I think I may have accidently just fallen into a gold mine. I had previously purchased the USB to Serial Adapter recommended by Mike Dabrowski to log data from the grid charger. It is SewellDirect.com part number SW-1301, and comes with the driver on a CD. According to the package, it give me a bus powered serial port to my modern laptop.

I'm home free - Right

Yep, should work just fine.

OK, now I think I understand. Peter recommends a cable which works directly to a USB plug, Eli recommended a cable, in post #27, which ends in serial plug and requires an additional adapter. I bought the wrong cable, the one that Eli recommended, but hey what is a couple of bucks among friends

Eli, you should edit post # 27 before someone else goes down the wrong road, or the right road if they already have an adapter. Just make the choices a bit clearer

I think I'm still functional, because I fortunately had already bought a serial/USB adapter. Nothing lost - I think

It's hell when everyone is typing and "sending" at the same time

I'm not going to recommend that people spend another $25 on a device that already approached $200..for a simple cable, no less. The $6 cable plus $2 serial to USB converter is fine.

Obviously it's up to the individual on what they want to do. The options are out there.

Ok, I understand. It had occured to me that I myself had accidently fallen into a cheaper option - since I already had the adapter. Cheap is good - as you say. But do think a bit about editing post #27 to make the options a bit clearer. No hard feelings I hope.

[Eli]

Nah, not at all. I'm just self conscious about the price I guess. I edited my post to include both options.

Hooked us my OBDII C&C to my "new" silver 2001 that I got the good price on for the "dead" battery and IMA lights. Went out and did the Amp/hour counting test with some pretty sad results. Did the test twice and got .64A/h in 1:44 minutes, and .67 A/h in 2:54 minutes. So, it does appear that the battery is very weak.

Of some interest to me is that with my hypermiling type driving, it hasn't thrown an IMA light so long as I keep the battery SOC 70% or so.

One problem the guy had was a bunch of bad grounds and I notice he replaced all those cables. I'm wondering if that might have been partially responsible for the IMA light?

If the battery has got lazy and is just suffering from lack of capacity then cycling using mima/soc reset feature/grid charger discharger may recover capacity.

Removing the pack and cycling the sticks on an individual basis is best to recover capacity if you have the time.
