    • Little smaller than factory wet cell battery
Will come with a spacer to raise the battery up to fit in the space allowed. Otherwise top battery hold-down will not fit. Battery will be shorter and narrower than stock. Put included spacer underneath battery.

Unfortunately, after less than a year the battery proven to be defective and vendor was unable to provide a replacement so on return of item the vendor issued a full refund. Would not hesitate to order any other product vendor sells as they fully supported great business practices.

I replaced a Diehard lead acid battery that failed in under a year with this Bosch AGM battery for my Mazda 3. It’s a little smaller than the battery tray but won’t be a problem once I secure it with the brackets. I’m very pleased with how well it turns the engine over to start, and it appears to have alleviated the lower power faults the “old” battery was causing. I’ll update if my opinion changes, but 2 days in, I’m glad that I chose a higher-end battery. ... show more

    • Love AGM Batteries but not as of 6-2020
My last car had a Sears AGM battery that went 5 years+. That was a great battery. I've only had this battery for several weeks now but I'm pretty happy with it so far. I like this one for two reasons. First, it has a built in handle that basically folds down into the battery so that it is out of the way. With other batteries, AGM or regular, they seem to have a built in strap that arcs over the top of the battery so either you're going to have to cut it in order to get a top battery bracket to mount in place or be lucky enough that the battery strap can be positioned out of the way. If you end up cutting the strap, you'll have a tough time removing the battery if it becomes necessary for one reason or another. Secondly it has more reserve power than the standard battery that it replaced. I run quite a few accessories and I find this to be a bonus. If I had a complaint, it would be that the battery is too small for my battery tray even though I installed the recommended group (size) battery. It's being held firmly in place by the battery bracket but I would have felt better if the battery's footprint matched the tray. Update 6-2020: The battery has failed after 4 years. I'm a little disappointed by that since you pay a premium for an AGM battery. My last AGM battery went 5 years+. The only reason this battery died was because my truck sat in my driveway for several weeks during the COVID-19 quarantine and no matter how much I drove it after I jumped-started the battery, it would die a day or 2 later. This happened repeatedly. I see it's currently available on Amazon, for a while it wasn't At that time I had ordered a Northstar battery from Amazon (see my review- stay away). AGM batteries are great if you run a lot of accessories and they also have a lot of cold cranking amps. If you have a big engine or a high compression motor or just need to be able to start your car up on a cold winter day this battery is more expensive but I had hoped it would have delivered longer service. -------------------------------------------------------------------------------------------------------------------------- I rely heavily on reviews when I make purchases so I put some time into reviewing everything I buy on Amazon for personal or business use so I can help other people considering that item.

    • Battery arrived 1-day earlier than promised
Only 4-stars as I've not actually installed this year. Have been enduring so many car not starting issues with this 2011 V6 Toyota RAV I got about 1 1/2 yrs ago with less than 45,000 miles. Bought a new battery. Didnt matter. A week later it was dead. Had to call tow service so many times I had to up my membership to gold to allow for 12 road service calls a yr. Even had to have the car towed to the nearest dealer 85 miles away and back. Everyone said cant find a thing wrong with this car. Really!? So all cars of this make just eat batteries and dont start? Lovely. Ended up getting a trickle charge put on the battery to plug into the wall anytime I'm not driving it. Oh yeah, was told it was my fault that I dont drive it enough to charge the batteries. Read from a mechanic that 9x out of 10, he has to replace batteries on Toyota RAVs and their Van, due to a parasitic drain caused by the power steering set up. So, hoping this battery can enable me to pull the plug on my car as having to be plugged in certainly can put a limit on where you can go with your car. If this battery cant save it, next is selling it. Dont look forward to that. ... show more

    • Best battery out there
I love this battery. It is like mixing a starter and a deep-cycle battery into one. Last for days on one charge that only takes maybe ten minutes. Works all my after-market accessories, including heater, five fans: one for the cabin, the others on the radiator, and lights with no trouble for about 10hrs. Plus, it will still start the car with all that power consumed. ... show more

    • Good Battery, but...
This purchase was to replace the same Bosch battery, which functioned very well for the past 6 years. The positive post diameter on the battery is ~10 thousandths of an inch smaller than the previous battery and I had to shim the battery post so that the connector on the battery cable would tighten on the post. Installation was a PITA, and despite saying that it fit my year/model car, it did not. ... show more
