I have bought eight or possibly more, no fewer, batteries from Dyno. I purchase them for one reason…read moremore than any other, quality. If one were interested in proving the point simply take a Dyno battery and a battery from any other supplier such as those through O'Reilly Auto Parts. The O'Reilly are good enough but Dyno are better. Simply weigh each and you will find the Dyno battery about 20% heavier. That is due to Dino's use of more lead. That means you can run down each the same amount and the Dyno Battery will have a reserve of power not available in the O'Reilly battery. There is a reason why all of the fisherman going up the inner passage to the Alaska fisheries use Dyno. Running out of juice in a storm might mean the ship will founder. Where a fisherman's life depends upon the battery, fisherman trust the Dyno battery. The service is far better too. Relative to my own car, a Subaru Legacy, for example, the owner, Mark Allen Knowlton noticed that the battery shelf in my car was appropriate for a 27 series battery despite the manual indicating the lesser 24 series battery was the recommended battery. He recommended I move up to the larger battery though they were relatively close in price. The only difference between the two series is that the 27 has more cells, thus, more cranking capacity though otherwise they are the same, i.e,, the same voltage. This winter, I have noticed the difference. This extra cranking amperage is a big deal when it is cold out. The 27 catches quicker, charges more fully, and assures the start up fuel charge is more consistent with the designed charge because the injectors have full power despite the cranking voltage drain. Far better for the engine and more likely to start immediately. Good for older cars especially. All in all Dyno has all my family's battery business.

They immediately did a thorough job inspecting and testing the battery with no evidence of any issues with the battery and confirmed it was producing over 960 CCA which was great for it's age and use.

The new battery is working perfectly and I wanted to call out a company that stands behind it's products which is becoming so rare nowadays. Great job and thank you Dyno Battery team.

After installation of the inverter cable from battery to rear of the cab he took me through his work sharing what he did and why. We also discussed the scope of what would be required for a future install of the "Big 3" and I left grateful at the competency I'd just experienced.

The diagnoss was I needed a new hybrid battery... estimate $6,600 including a new 12 V battery. I didnt think it was prudent to spend that much on my 2007 car and researched options. They were more epensive at Toyota dealers and the diagnostic test were as well. Toyota no longer makes hybrid batteries for the 2007 Prius so they are refurbished with 1 or 2 year warranties..for ove 6K A very nice place that sells 12 V batteries for my car told me to contact Greentech Auto in Auburn. They explained that there were choices .. a refurbished with a 1 year warranty that was made to last for 2 years, a 2 year warranty refurbished hybrid that was made to last for 4 years and a 4 year warranty battery with new cells that was built to last for 8 years. The price for the 4 yer warranty was $2,700 and they would install a new 12 V battery as part of it with no labor charge if I provided the battery. I got one at Napa in Bellevue. They said it would take 2 weeks to make the battery with new cells. I had my car towed to Greentech in Auburn. The 4 year warranty battery was ready in 5 days and they called me that it was finished. They said I didn't need a new 12 V becaue once the new cell hybrid was installed it started and ran perfectly for days, so it was holding the charge. I don't drive on highways so they delivered my 2007 Prius to my house at no additional charge and gave me all the paperwork. They were knowledgeable and clear about keeping ny hybrid battery in good condition. With gas prices what they are I am thrilled to have my Prius in working order and not having to buy another vehicle under pressure. Greentech makes hybrid and electric batteries. They actually suggestd I get the less expense battery since I don't drive very much. The warranty on the hybrid with new cells is transferable to a new owner if I sell my car. BRAVO Greentech. Bravo to the battery place Pacific Battery in Kirkland that recommended I check out Greentech. Bravo to Tony's roadside assistance for coming so quickly to jump sta and my battery and being straight forward about suggesting I need to check out anytt other issues my car had. I whole heartedly recommend Greentech Auto in Auburn, and the other auto professionals who gave me excellent advice that did not line their pockets.
