YTX14-BS

Excellent, works great already on year two and the battery holds a charge and starts right up.

Like many, many other Pacifica owners I was getting the dreaded "Start/Stop System Requires Service" notification on my wife's 2018 van. This went on for several months and I didn't really think much of it. I did do some reading about the system however; it looked very confusing--so I left it alone. We don't really like the feature anyway (for those who don't know--and yet still care to know--this is the system that allows the car to turn off at stop lights and such and then restart as soon as the driver's foot lifts off the brake pedal. It's supposed to save $ on gas). Then, my wife called me from Costco to tell me that her car won't start. She called me back about 10 minutes later and said the car had now started and that a bunch of warning lights had popped up on her dash. We now had several warning lights up on the dash: the symbol for the start/stop system (which was nothing new...this one had been on for weeks) and now the check engine light was on. Correlation is not causation but I assumed that the start/stop system had something to do with this. Great. Now I was going to have to take the thing back to the dealership and offer to trade them my first born son in exchange for making this right. First, however, I decided to do some sleuthing. Digging in to my bag of tricks, I busted out my multi-meter and tested the battery. Low and behold, it read 12.5 volts--indicating the battery was JUST hangin' on. I tested it again a bit later and it was lower, reading 12.3, then 12.2. I figured I was probably on to something. Here's the (tricky) thing: these dang machines have TWO batteries! One big primary battery (the crank battery) and one small auxiliary battery (which is used by the start/stop system. You know this already because you are shopping for a small auxiliary battery and reading this review). The things is, you can't really check the voltage of just one when they are both in the vehicle and connected in parallel. Both batteries will read the same voltage. So, I knew that one of the batteries was dead but didn't know which one. I took a chance and ordered this battery, at the time hoping I wouldn't have to also fork out $200 on a new primary (crank) battery. Fun story: I had to buy a new crank battery, too. So, the new battery arrived on Sunday (yesterday) and I started disassembling the old batteries out of the van. Remember when removing a battery used to just be a strap over the battery and disconnected the negative and then positive terminals? Ha! No more! It took me darn near 45 minutes to get the two batteries out (for the record you need a 13mm and 10mm socket). The small battery has to come out first; the crank battery does not have room to come out unless you pull the auxiliary first. I got the auxiliary out and inspected it to the new replacement: they looked very similar in size and the labels indicated very similar properties in terms of capacity and such. The one big difference--and this was noted by another reviewer to my benefit--the old battery had posts mounted to each of the positive and negative terminals and the new battery had bolts that were supposed to connect through the terminal and then into a square receiving bolt. The problem was, the bolts that came with the new battery are rather short and--at first glance--don't appear like they will work. I'm getting ahead of myself in this story but when I went to put the new battery in I was able to make these bolts/nuts fit by cutting a rubber band in half, folding the rubber band over itself to about 3/8" height, and then squeeze the square receiving nut into the battery terminal with the battery under it. This pushed the receiving nut up and tight against the underside of the terminal and made it so that when I pushed the bolt down through the terminal the threads would catch. Saved me from buying longer bolts (a savings of probably 50 cents--still, it worked!) Now that I had the auxiliary battery out and it looked like it would work, I decided to pull the main battery and take it to an auto parts retailer to have them check it. The first one I drove to closed literally as I pulled in (because of course it did). The second, an Autozone, checked the battery for me: they measured it at 75% cranking power while at full charge and labelled it "dead." Gone are the days of a battery slowing dying; cars now are entirely electronically controlled. My suspicion is that if the car reads a certain level of battery it just stops working. There is no slow turning of the starter like on older vehicles. The Pacifica seems to be especially hard on batteries and so won't take anything but the battery's very best. Once performance falls below a certain point it is "dead" for all intensive purposes. $203 later, I had a new battery with a 36 month warranty. I took the new battery home, installed the big/crank battery first, then the auxiliary battery (then removed them both again because I had put the crank battery in backward). I reversed the multitude of cable connections to the battery exactly as they were before and...it worked! After a few miles of the car telling me the start/stop system was unavailable because the battery was charging, it became available and I had the joy of being able to turn up my music with the windows down so that everyone around me could listen to what I was listening to without the annoyance of the engine idling. I bet I looked PRETTY cool in my mini-van. With functioning start/stop. Long story short, this battery worked for what I bought it for. I have no idea how long it will last but--considering all other options for this battery are well over $100--even if I have to replace it twice, or even three times, as often, I still won't be losing much by giving it a try. I'll update this review if it fails ridiculously fast.

Battery fit correctly and is working great.

Perfect replacement size for the battery in my classic 1965 BMW R50 motorcycle. Great price. My only quibble is that the nut into which the terminal screws fit is not attached. Therefore, you somehow have to line up the screw with the nut somewhat blindly. I actually had to remove the seat to get at the terminals. Your mileage may vary. Overall, very satisfied.

Battery worked great so far the battery sat all winter without discharging

Reliable, Maintenance-Free Power for Motorcycles and ATVs I’ve been running the Weize YTX14-BS battery in my ATV, and so far it’s been exactly what I needed. It comes fully charged and ready to install, which saved me the hassle of dealing with acid packs or waiting around for an initial charge. The build feels solid, with a sealed AGM design that doesn’t require any maintenance or topping off. That alone makes it a nice upgrade over older-style batteries. On first start-up, it cranked my ATV engine quickly and confidently—no hesitation at all. The terminals are sturdy and made installation straightforward, though I’d suggest double-checking fit since some battery compartments run tight. For me, it slotted right in without an issue. One thing worth noting: this battery is marketed as “high performance,” and while I can’t speak to the long-term durability just yet, it has held charge well even after sitting for days without use. That’s encouraging for anyone who only takes their bike or ATV out on weekends or seasonally. The only minor watch-out is weight—it’s not feather-light, but that’s to be expected with a sealed AGM. The benefit is you don’t have to worry about leaks or spills. Bottom line: A dependable, maintenance-free battery that delivers strong starts and reliable power. If you’re looking for an easy swap-in replacement for your ATV or motorcycle, this is a solid choice.

Well made and cheaper than other similar batteries

Welp, i had this battery on the trickle charger inside my home all winter, waiting for spring to arive so i could drop it in my Yamaha RS Warrior. Sometimes giving it a break a few days here and there every week. I went to start the bike and noticed that my starter was very slow. It eventually started. I thought that maybe because this was the first start of the bike after sitting a few months and everything would be fine. I put the trickle charger back on the battery after the ride. A day later the same thing happened starting the bike and the battery lasted only three revolutions before completely dying. I mean zero voltage. I took my multimeter to it and to my surprise it was completely flatlined!!!!! I grabbed my old battery from last year that this one was supposed to replace and it read 12.5v. My return no later than date was January 2025 in the middle of winter. ***I was contacted after submitting my review from the seller. Even though the window had lapsed to return the battery they offered a free replacement or my money back to make things right!! I had since bought a locally sourced new battery this spring and so i opted for the money back. Customer service i must say really was something special and caught me off guard here. I would definitely buy from again knowing that id be taken care of from these folks. I changed my original one star to 4.

My wife Pacifica auto start stop was not working, removed old battery installed this battery and working like a charm !! 100% recommend this battery if you Pacifica is having same issue. Thanks to the guy with previous review who had same issue with Pacifica.

terminals were backward for my motorcycle ...tried everything...does not work even though application said it would....it was too late to send ...so I have a useless battery sitting in my garage
