OPTIMABatteries High Performance DH7 YellowTop Dual Purpose Sealed AGM Car, Truck and SUV Battery, 880 CCA, Maintenance Free, Versitile Mounting, BCI Group Size 94R

Great quality Batteries I have not ever had any issues with Optima Batteries that I have bought I had 2 red tops they both lasted around 7 years each great battery life. This is the first Yellow top I have bought.

Installed in my 2017 Jeep Cherokee. Works great, as expected from an Optima. Perfect fit and handles my electrical needs.

This battery should have come stock with my 65K f150 2022, the factory battery is junk, with all the electronics on new trucks, the factory battery didn’t even fit/fill the battery tray!! This battery does, and no issues if your truck sits for a week , like factory battery!! Ford service department SUCKSITS expensive but I feel it’s worth it,Absolutely recommend!!!

Length & width match, height perhaps 3/8 inch lower than OEM, shimmed top with some very firm foam duck taped under the hold down bar to stay in place. 10mm socket/wrench for battery terminals & both ends of hold down bar. 13mm socket 8+ inch extension for clamp holding rear end of battery to floor. Use a bit of thin wire, like a long bread bag twisty, to hold clamp&13mm bolt to end of socket/extension, makes it easy to reach down in there and line it up. BMW's will need battery registration with computer attached to OBDII port. Installed easy enough, will be years to know how it holds up.

Working well now I need an alternator

What can I say? You get what you pay for. These are high-quality batteries that are very reliable and are my go to whenever replacing batteries. I’ve made the mistake of trying others that were nowhere near reliable, and a waste of money

Bought one locally dated December 2021 on battery, started being unable to start my Jeep by December 2022 if it sat for more then 1-2 weeks. Went back and forth with AZ, they wouldn't warranty the battery if it passed the Cold Cranking Amp test (which it did), it would just self discharge with nothing attached to it, at a rate of roughly 0.125v per day. Past 2 weeks the battery was too low to start vehicle. Optima support said AZ has to warranty it and refused to help.Bought one off Amazon and received it in May 2023, it appeared to be brand new and shipped very recently from the manufacturer. Tested it about an hour after it was delivered : it was 10.5v. To be clear a fully charged Yellow Top should be about 13-13.2v. Typically 0% charge is considered somewhere around 11.5v, and most vehicles won't start that low. Additionally, on Optimas website they state anything below 12.4v causes sulfation which will permanently degrade the capacity of the battery (especially the longer it is that low). Hooked up a battery tester I have that claimed about 50% State of Health.I don't know if Optima is failing with this model battery in specific. I don't know if they've changed manufacturing quality since they were sold in 2019. I just know this is not anything like the 2 dozen+ red, blue, and another yellow top optima I've bought in the past 2 decades for various applications. For ex: I bought 3 blue tops around 2019-2020 for my RV/solar, one of which I never installed, and it read today (roughly 3 years later) still 12.5v. It lost considerably less charge in 3yrs then this brand new yellow top did in the couple weeks it took them to ship it to me. Over the decades I've also had multiple red tops on other vehicles that can sit for months, and NEVER hesitate to start, even sitting in -20c temps. While this review only has a couple of people stating similar problems, look at the slightly smaller Optima DH6 Yellow Top reviews on Amazon, and you'll see DOZENS of other people describing this exact same fail pattern of self discharging, dead on arrival, and unable to start car after it sits for a week or so.I'm unfortunately going to probably go back to one of the other AGM H7 clone batteries from a local store. I got 3 years each out of those before, and they were half the price almost of this junk battery.Optima may have lost my business permanently, but I doubt they care, if cutting quality and costs makes them more money.

I always had Optima Battery B4, I haven't had one for a while, but I known that they last. I really needed a new Battery in my vehicle. I will see if this Optima Battery will last me 7 years like the original chevy one I had. Love the way it looks and fits nice, plus I have a subwoofer in my vehicle and Optima Yellow Top are known to handle the bass.
