Civicowner,
I just received my refurbished battery from Hybrid Battery Repair.com 8 days ago. Since I am very local to the business (I'm in central NJ), I drove to and from the site for both the battery removal and re-installation.
While I can't offer you any solid evidence - yet - of the durability of the refurbishing, I can say that everything seems work as it did before I brought the battery pack in for repair: The IMA, autostop, the charging and discharging, etc. And I definitely plan to post when the 1-year warranty period ends on how the battery performed overall.
That said, you mention the "2-3 week turnaround" time as a concern.
On October 1, 2010 I drove to Hybrid Battery Repair.com and had the battery removed for refurbishing. At that time, I was told the repairs were running "4 to 5 weeks". While this seemed like a long time, it was a cheaper option than a new battery, and environmentally more responsible. Within a day I authorized a $500 payPal transfer as a deposit for the work. Fast forward 4+ weeks...
I called the company on November 3rd (or 4th) to confirm pick up on November 5th, 5 weeks after the battery was dropped off. My call was NOT returned so I called again on the 5th and spoke with the owner and was told that I needed to call his tech to get an exact delivery date. When I called her and got it, and I was shocked: November 24, 2010, almost 3 weeks later.
At this point, I became somewhat irate: Hybrid Battery Repair had my battery for 5 weeks, they had my deposit, and they had my message that I was expecting to pick up the battery that day, and they had NOT respond to my call, and now the delivery date was pushed back 2 1/2 weeks.
FYI, driving your Insight without the battery is harder on the engine (and I would say the clutch too, if you have a manual like me) and you lose the punch of the electric motor, which you need for climbing hills, passing, etc. And the starting from a 12 volt is a lot rougher too.
On November 8, 2010 I sent the company an email stating that I needed a firm answer to the question of whether the battery would actually be refurbished by the 24th or not. I wanted something in writing as I was concerned they would miss this delivery date too. In my words: "at this point, I just need straight talk from you - no spin, no optimism, no bullshit."
3 Days later, in a email, I was told the battery would be ready the 22nd of November. Indeed, I did have the battery re-installed on November 22, 2010 - 7 weeks and 3 days after I dropped the battery off - and things so far are working fine.
Why is it necessary to become irate to get people to do their jobs? i.e. respond to their paying customers, make reasonable estimates, and keep them informed as to what is going on? This seems to me to be somewhat of a pervasive problem.
Bottom line, think hard before parting with your battery and get delivery dates in writing.
