your profile does not include your state, so shipping cost could be a factor in the total cost (with regard to BB -further away from Oregon, higher the cost.
I just went straight to a shop very close to where I live, bought new w/ 3-year warranty, they installed it. total $1800
If something happens, I drive down the street and resolve it.

did your battery have 11 years/170,100 miles warranty?

Sorry for the delayed response. ptb, Iím in Iowa, so my original warranty was 8 yrs, 80,000. Even after extension the battery was still performing okay after 9 years. Not like new, but it wasnít anywhere near throwing codes so my dealer would not have replaced it. I know there are people who have talked their dealers into giving them new batteries under certain conditions, but that wasnít going to happen here.

SKieth, thanks much for sharing your knowledge.

Jody, Iím glad you had a good experience in Raleigh. I might call the guy to understand where he sources his batteries and how he matches them. His prices look good but I can install myself with little trouble so the free installation isnít that valuable to me, and a trip to Raleigh would offset the savings vs Bumblebee. I canít imagine he does better than them based on SKiethís info. Thanks for the reference, though. Iíll definitely check it out.

Re: Looking for recommendations on battery pack replacement
 
Put my new Bumblebee battery pack in this weekend. Surprisingly easy to install. It didn't come with any directions, but I found a YouTube video that walked me through it. There was a black ground that needed to be disconnected/reconnected which wasn't shown on the video, but it was easily spotted once I pulled the old pack. The hardest thing about it is getting the seat back off and on. I'd done it myself before and knew it was a bear, but this time after struggling with it for awhile I got some help. With two people it's a breeze.

The pack weighs roughly 75 pounds, but it has some lifting handles on the front, so it's not that hard to get out and in. They want you to keep the packaging and return the core in the exact same packaging. They provided a self adhesive FedEx return sticker, so that part was a piece of cake.

The only thing that was a little disconcerting was I wasn't sure if the pack had a charge on it from Bumblebee. When I started the car with the new pack, it started from the pack (not the 12V starter), but I had zero bars. After about a minute of idling the bars started appearing and a few minutes later it was at 8 bars.

I would say it runs like new now, but when it was new the infamous software update for "extending" battery life had not come out yet, so it acted quite differently back then. Wish we could go back, but....

Anyway, I'm very happy with the performance and it's good to know I've got a solid pack with a 3 year warranty behind the seat.

NiMH SoC can't be evaluated in a resting state.

When you disconnected the 12V, you wiped the battery status from memory. At next start, the car evaulates the 11 tap voltages to ensure they meet minimums and if so, it starts the engine with the IMA battery/motor. It then initiates an evaluation routine where it charges the battery at idle to see how those 11 voltages respond to 5-6A charging. Once it sees how they respond, it can estimate the SoC and report a value on the gauge. If you don't allow it to idle until the SoC gauge responds, the car conducts the evaluation based on charge/discharge response while driving.

What you describe sounds 100% normal.

The software update *should* enhance the life of the battery. Honda previously permitted discharging down to 20% SoC. Now it is more restrictive - closer to 40% - like the Prius. The patch was problematic because SO MANY OF THE BATTERIES WERE ALREADY SUBSTANTIALLY DETERIORATED, the loss of the additional 20% of operating range at the bottom meant one or more of the 11 tap voltages was triggering recalibrations at 40% SoC where they weren't before. For a fresh or healthy battery, the patch is goodness. For an old and tired battery, the patch could be very problematic.
