Delphi BU9094R MaxStart AGM Premium Automotive Battery, Group Size 94R (Reverse Terminal)

Worked great for awhile. Then just suddenly cranked over slow. Then dead next day. Not completely dead but couldnt start the car. Had battery tested. Test came back as a bad battery. Kinda pricey for only 6 months of use i think

I’ll revisit this review if I have any issues down the road but:The battery showed up in 3 days (we are still in Covid delivery mode where not much is 2 day Prime).It was dropped off by a trucker, no box (not unusual for a battery).The battery was dated 5/20 (it’s June 10th) so it’s fresh.It comes with handles and protective plastic post caps (to be removed for use) and + clearly marks the positive side in red on the battery.I ordered an R94 to replace a battery on a 2013 Dodge Grand Caravan. It fit perfect and is an upgrade in CCA (800 versus the stock battery’s 730). Reserve is 140 minutes.In case it matters to you this is an AGM battery (absorbent glass mat) versus a flooded cell (conventional) battery. AGM has less chance of leakage. Usually they have faster recharge and a deeper cycle.The battery is a typical 3 year warranty.

I ordered one, based almost entirely on a Camaro owner's review while doing preventative maintenance tasks. The moment I received it, I laid a multimeter across the battery terminals, and it was 12.6 volts. It was still 12.6 volts after installing it in the trunk. Then the in-dash computerized voltage indicator read 14.4 volts, -after- starting the vehicle, and the multimeter confirmed 14.2 - 14.4v at the battery terminals while the engine was running.This U.S.A.-made Delphi car battery is an immediate upgrade from the Mexico-made OEM Mopar battery, with almost 100 more cold-cranking amps, and significantly higher reserve. It actually made the stereo louder and clearer both while driving, and parked with the engine off, because it is sending a stronger current to the amp. Battery was manufactured not quite two months before purchasing it.No issues installing it. Perfect fit, as advertised. The battery comes with two vent holes for vent tubes, new hardware for the vent tube and vent port (a 90 degree plastic pipe), and one plastic plug, to insert into the vent hole you are not using.

I have never purchased a Battery online. I purchased this one and as promised it is Exact fit. Upon delivery I checked the Voltage. Voltage was at 14.0 volts. I even noticed that there’s a vent hole with 2 extra tube fittings. I am Highly impressed as I am a retired Class A Mechanic. Road tested my 2015 Camaro 2-SS immediately noticed a 2% charge rate increase. Please note all, I changed out my Battery because I do pm everything I own ( Preventive Maintenance) and it was 4 1/2 years old. I Live In Florida and FYI Heat is worse for a Battery than Cold.

My OEM battery lasted 7 years with no issues, but I decided to not push my luck and replace it with this Delphi battery. Unfortunately, after 6 months (and only a few thousand miles) I began having issues with starting difficulty, the radio resetting, and eventually a check engine light for low voltage, which I was able to confirm with a multimeter. I thought there was no way a battery would fail that soon, so I assumed I had something more serious wrong with my vehicle. I took it to the dealership since I have an extended warranty on the vehicle. They diagnosed the battery issue and replaced it. Since it wasn't a covered event, I had to pay $400+ to get out the door, including an extra core charge to keep the dead battery so that I could get a refund. I contacted Delphi since the battery is well under the 3-year warranty limit. They informed me that since it is sold through Amazon the warranty coverage goes through Amazon. I have contacted Amazon multiple times now. At first, they sounded as though they were going to be very helpful (which has been my experience before), but now I'm getting no response. So, it looks like my $200 battery will now end up costing me $600? Very, very disappointing.UPDATE: After several email messages, Amazon has now refunded my money for the battery. Leaving the review as one star because there's still no reason the battery should have failed so soon. In the future, I won't be buying automotive batteries online.

Fits 2015 Mercedes C300 without modifications. The ECO Stop/Start stopped working. Replaced battery with this it’s fine now. Car starts right up even after few days of no start in dead of Pennsylvania winter.

Excellent quality battery at a very good price. AGM batteries are a step up from the lead acid. This Delphi AGM battery is only slightly higher cost than a standard battery. The Delphi battery is a good value. It is also much heavier than the one it replaces.

I ordered two for a Cummins truck. They fit and worked perfectly. My OEM batteries were 3 years older than the truck, so the dealer/manufacturer really hosed me. It is nice having two heavy batteries delivered 6 feet away from my truck. 20 minutes later, problem is solved.
