I have a lot of amateur radi equipment i my Hummer H3. The total current draw from the radios and…read moreamps can be 180 amps. I installed 2 Odyssey PC1500 batteries and had him build a 14.4 vdc alternator at 300 amp output. It works perfect. The Odyssey batteries are 13vnc instead of 12 volt so the charge voltage needed to be raised. The engineers at Odyssey recommended the 300 amp charge rate. I also purchased a 20 amp charger from Odyssey to condition the batteries. Since doing this, there have been no problems with any of the charge circuit and after 2 years there is no discernible degrading of the batteries. I checked the current output capacity and it has no problem in providing up to 285 amps. This is about all the computer actually demands to keep up with high current drain which is seldom. Most of the time I only use about 120 amps current draw while on HF and using a 500 watt rf amplifier. I regularly check the output with a portable Fluke 199c Oscilloscope and see good clean DC voltage with no noise even while high current demand. I do this because I have over $20,000 worth of radio equipment that needs proper and safe voltage. I have never had any damage to any of my equipment . I don't know what the other reviews experienced with their alternators but mine has worked flawlessly. Robert S. BSME MSEE Member IEEE and ASME EXtra Class Amateur radio operator.

I have never once made a review on Yelp for anything but this one absolutely had me so infuriated…read morethat I believed others should find out about it as well. I made an order through down4sound which I have found to be very reputable and had nothing but great customer service through my multiple purchases. When I reached out to the D4S team, they expressed that I needed to contact excessive amperage directly. I did just that and received one response with a promise to send missing parts and the manual that I did not receive. This was requested in June of 2026. As of this review, it is August and I have still not received a single response or parts for the alternator. I have since sent three separate emails in which no response was ever elicited. This company is so infuriating and has no interest in public service once you have forked out money from your butt to get a nice alternator. Please take note of any and all reviews and note that every one of them are true. This company sucks and I regret ever spending my money through such a bottom feeding human.

This may be the best AutoZone I have ever been in, if you ask why I'd say my shopping and checkout…read moreexperience required absolutely no customer service or interaction with the staff although it appeared the entire staff was sitting on their butt behind the parts counter doing nothing, I didn't even get a "good morning" or a "how can I help you" or a "thank you" this made for an amazing experience and I was in no way offended by their lack of effort. I walked in found exactly what I needed, (2) boxes of DEF for my motorhome threw them on the counter, grabbed the scanner, inserted my credit card, printed my receipt and walked out I ask you how amazing is that? Noooo I didn't need to provide my phone number or email address and I also won't be getting a bunch of junk in my inbox or unsolicited text on my phone this alone is well worth not receiving any reward points or promotional emails. I only hope this a trend that will spread across this brand which would definitely be a reason to shop at AutoZone verses the other two major brands and maybe just maybe this could reduce their overhead and lower their prices...

I have had good experiences years ago, but now the charges are way too much !…read more They quoted the labor at $300.oo, then charged $785.oo to repair breaks , alternator, and a small oil leak. That's nearly $400. per hour for just labor. The parts were $1068.01 , Shop supplies charged twice $60.oo, Tax $129.47, Total if cash = $2000.oo , but my ride had left, so I had to pay an additional $129.74 to pay with my checking account debit card ! They charged for a " Thorough inspection" But there is still something wrong with the wheels or tires. The calipers aren't even new . Looks like they wiped old ones down with oil and the caliper on the left is still tight.
