I purchased this battery to replace the factory Varta AGM battery in my Mini Cooper that reached the end of its service life. While a little hesitant to purchase this sight unseen, but the battery is basically identical to the original one and fit perfectly in the compartment. Starts are quick and effortless now. I can't say how long this battery will last but for now it works great and I'm happy with it. Plus it was less than half the price of the ones available at the local auto parts stores.

I’m running this AGM battery in both my Mercedes E-350 and Mercedes G-550, and it’s been rock solid. Fitment for Group 49 / H8 is perfect, starts are strong, and voltage remains stable with all the electronics these vehicles carry. It performs exactly like the OEM battery - at about one-third the price of what the dealership charges. Excellent value without compromising quality.

I recently purchased the Weize Platinum AGM Battery (Group 49), and I'm very impressed with the quality and performance. The delivery was on time and the packaging was perfectly wrapped and secure, which is crucial for a heavy item like this. The installation was straightforward since the dimensions were exactly as specified (BCI Group 49). The real value is in the performance: the engine starts quickly and powerfully, even on cold mornings. It runs quietly and, so far, has maintained an excellent charge, which speaks to the quality of the AGM technology. Considering the price versus other premium brands, this Weize Platinum offers impressive durability and power. A great product and a solid upgrade!

Let me start by saying, this battery DOES fit a 2008-2016 Chevy Cruze Gen 1 (Amazon says it doesn't, but the H7 DOES fit. DO NOT TRY THE H8! Too large even cutting the battery box)! Now to the battery itself, its reading out at 14.8v and fired RIGHT up. Strong "ey-eff" and its 40F outside! I originally ordered the H8 which Weize was kind enough to allow me to return for a small 35 fee. (Which I was glad to pay out of the refund money, not an additional payment.) Overall its a great battery and with a 3 year warranty, you really can't go wrong! Get you one, ditch the Die-Hards/Interstates, save some $ and get an awesome product!

We purchased this battery in March 2024. Recently our car has been getting harder to start. A few times, it has not started, which is a big issue when our car has auto stop/start and won't start the engine when the traffic light turns green. We tested the battery today (August 30, 2025) and it shows it already needs to be replaced. At 99% charge, it is only producing 494 CCA (rated at 760 CCA). Up until now, the battery has been great. It was well packaged when shipped and fit properly. Since it is still under the 3 year warranty, I submitted a warranty claim for the battery with Weize. I'll update this review later as I hear back. 9/5/2025 EDIT: Weize sent another battery under their warranty replacement program. The turnaround time was quick, around 5 business days. The new battery is testing strong at 885 CCA. In light of the easy warranty process and quick turnaround, I have updated this review from 2 stars to 4 stars.

I needed to replace the battery in my 2012 Mazda3 that had a shorted cell, and this battery was a great deal, especially for an AGM which is superior to a traditional lead-acid battery. The seller shipped it promptly, but FedEx took their time getting it to me with predicted arrival times of last Wednesday or Thursday, which then turned into Friday, which ultimately turned into Monday (today), when the battery arrived. The packaging of the battery is excellent, with foam all around it to keep it safe in shipment. It arrived charged to about 12.7 volts, which the instructions assured me was enough. If you've ever changed a battery, this one will provide no surprises, and if you haven't changed a battery ... well, it's a simple process. The group size of this battery matched what I took out, so the fitment was perfect. The car started easily with the new battery and performed fine (I keep an eye on battery voltage with an OBD II monitor). Only time will tell about longevity, but my initial experience is totally satisfactory.
