OPTIMA Batteries High Performance D75/25 YellowTop Dual Purpose Sealed AGM Car, Truck and SUV Battery, 620 CCA, Dual Terminal, Maintenance Free, Versitile Mounting

This was for a RAV4 Hybrid that gets little use now that we're retired. It replaced an Odyssey AGM battery that failed due to little use. The Odyssey was a starting/deep cycle battery, the Optima is a full deep cycle. The RAV4 Hybrid never has to start an engine, so the starting capability is wasted. Being deep cycle allows it to discharge more deeply without damage, much better for our use. Note that the D75/25 size IS NOT what is recommended for the RAV4 Hybrid, but it fits with some modification and fabrication. It has a lot more capacity than the one that is recommended, better for our use. It also does not have a means to vent the battery outside, which is necessary in the RAV4 (mounted in the cargo area). I fixed that by gluing some PVC pipe caps over the vents, with fittings to connect them to the vent hose. JB Weld Plastic Bonder 50139 works well to join the PVC caps to the polypropylene battery case.

Battery finally died in my Camaro had a buddy say this was the best for the buck. 283$ to my door instead of 350$ at auto parts store! Came charged and ready awesome!!!

Be prepared to order another one. I have been using, charging & restoring 12v batteries for decades. These Optima’s are generally a very good battery for rugged & abusive use. (Plows, winches, any type of heavy amp draw usage) I have a plow that also has a 10K lb winch that gets mounted to the rear of the F250, and plugs into the 00 cable to the front of the truck. Thai truck has 2-yellow tops. At any rate, I have removed the winch from the equation. And I have bought several yellow-tops for my F250 over the years. One will last me 3-years MAX. That’s w/one driveway that I plow ! That’s not very good. At any rate, lately I have been receiving BRAND NEW yellow tops DOA !!! Or, after 30-days the battery is DEADER THAN A DOOR NAIL ! It’s so dead (drained) that the Optima charger CANT EVEN BEGIN THE CHARGE ! Lol !!! All JUNK !!! So, you have to TRICK the dead better by attaching another battery that’s got voltage in parallel, and attach the Optima charger to the deader than a door-nail battery & the charger will begin to charge because it’s reading the battery that does have some voltage left in it ! Once this happens, remove the good-battery from the equation & the deader than a door-nail Optima battery will continue charging. That is, as long as it will accept a charge, and there isn’t any internal damage. So, I’ve had to call Amazon & tell them that the brand-new yellow-too Optima battery they just sold me for approx’y $280 is NO GOOD ! So, they can’t have you ship it BACK to them, so they do refund your $ & you end up stuck w/a bright yellow boat-anchor ! Which really sucks because then you’re stuck w/having to properly dispose of it. I’ve even tried & tried & tried to salvage these DOA batteries, to absolutely NO AVAIL. So, you just have to order another one & hope you get the luck of the draw ! What I think is happening, is AMAZON buys these batteries that are good batteries, by the BULK, and they DONT get bench-tested prior to getting shipped out to customers ! I bet they get taken right off of AMAZONS dusty old shelf & shipped out w/out as much as a volt-check ! Which really is piss poor, because AMAZON could truly save themselves & us Customers A LOT OF $ & A LOT OF HEADACHE if they just simply did a load-test & then a quick charge before it goes out da door ! So, I JUST HAD a yellow top optima arrive DOA this past spring ‘21. And I’m going to order another one today. And Jesus Christ, what happens if I get ANOTHER yellow-top battery that arrives DOA, again !??? Get my gd $ back & have to keep this one too !?? Amazon will start thinking I’m pulling a fast one on them ! Well, they best not, because I’ve been a loyal PAYING customer of theirs for DECADES. So, here we go ! Let’s see what happens. Maybe I’ll be back adjusting this review !?! Either way, be careful around batteries, they can ruin your day REAL FAST if you don’t know what it is you’re doing ! Over & Out !
