YTX9-BS Maintenance Free Lead-Acid Battery For Motorcycle, ATV, Honda, Polaris, Suzuki

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.

great price, decent battery, fantastic customer service!! Battery died 60 days after purchase, seller immediately sent a replacement for the battery. Even though it was past the 30 day refund window from Amazon!! I ordered this battery from this seller in February. The battery worked great until it didn’t. Idk what happened or why but the battery out of nowhere went completely dead. my bike started I began backing out of my driveway. I was low on fuel so I turned my bike off to close my garage and when I went to turn the bike back on I got nothing, zip, nada. At first i thought my ignition switch was dead so I swapped it with my old one. Still nothing. That’s when I said okay I’ll swap the battery to my old Harley one. Bike was slow to crank as the battery was dying, hence this replacement. But nonetheless the bike turned on and cranked over eventually. I hooked up the battery to my charger and it was so dead it wasn’t reading it at all. Knowing most motorcycle batteries usually get no warranty or only 3/6/12 months if it’s a fancy expensive battery. I read through the item descriptions and all I saw was 30 day amazon returns. It was past 30 days at this point. I was thinking oh well, serves me for buying a cheap battery even with the high reviews. But then said what the heck, Ill send an email to the seller inquiring about warranty anyways. i got nothing to lose. First reply back they asked for a couple pics showing the trickle charger I used and the info on it. (I think I might of actually bought it from this same seller ARKPOWER) And a photo of the battery on a multimeter which showed -0.07 volts. They responded back within a couple hours on a Friday night and asked to confirm address to ship a replacement. Wow, Totally awesome! the seller went above and beyond to make sure I was satisfied. Definitely recommend buying this as a oem replacement for an older EVO Harley. If the replacement dies in less than 90 days I’ll come update but my rating won’t change since I technically shouldnt of got a replacement anyways. But even if it does, I’d definitely buy from this seller again. Super satisfied with the customer service, so much so I logged in to write this review!!

Exceptional quality and price. Battery was a great fit and my four wheeler fired up immediately. Packaged well, arrived on time and very happy with my purchase. Sale price was so good, I bought 3

Nice battery. fit right on my 2014 honda rancher. Long term use is TBD, but so far works great.

I run it for my 1985 Honda Trx 250 fourtrax and it’s an amazing battary granted I only use it for a 50 doller light bar from autozone but it’s never failed in me and never died completely and Evan after hours and hours it’s still fully charged and ready to go I recommend for just about any atv tho

Moped batteries can be hit or miss on Amazon, this one ended up being fine. Key thing is on small batteries add a battery tender and keep a charge on it when you are not using the bike, you will extend the life of the battery. When a small battery runs low on a moped the charging system doesn't really have the necessary juice to charge it back up like a car would, so it has to be full initially before you ride to keep charge. Starts my big bore kit 70cc 2-stroke moped with no issues. Great price, great battery, highly recommended!

This did fit in my 2011 VRod however you will need to purchase or make a spacer for the positive cable. Harley Davidson has their terminals flush with the battery housing, I guess that’s why their batteries cost nearly $300 after tax but you can purchase spacers online or use a few washers to get you by. I had some electrical issues with my bike and Harley Davidson insisted it was my battery, so I purchased this one to see because I tested a bad instrument cluster. It came in and fit fine in the battery box but I had the issue with the positive terminal. The issue persisted and Harley Davidson also tested a bad instrument cluster and the bike had to sit for a couple of months for the part to come in. Thank God I had purchased the extended warranty every time I could. I got a call and the dealership informed me that my brand new battery was bad and I confirmed with my battery tester that this battery did in fact go bad. I contacted Weize and they were very helpful and professional. They refunded my money because the dealership took it upon themselves to replace my battery without permission and I was stuck with an OEM battery but I would’ve easily chosen this battery again. I have had this same brand in my Honda motorcycle for over a year with no issues.

Replacing batteries in a motorcycle is something I have to do every couple years. The bike does not get ridden frequently and I don't keep a battery tender on it as I don't have power where it is stored. This is my first time buying this brand. I had been using another brand that fit in the bike very well and was easy to install. My only concern was they did not seem to last very long so I wanted to try another brand. I saw good ratings on this battery and looking at the specs it seemed to be the correct fit for the bike. The actual publish measurements was actually 1/10 of an inch smaller than what I had been using. I received the battery and on inspection it looked very good. Well packed. I unpacked and put on a battery tender to bring it up to full charge. It stayed there for a week or two due to travel and other activities. A nice Saturday morning came and I wanted to get the bike out for a ride. I grabbed the battery and went to install in the bike, normally about a 5 minute activity. The first thing I encountered was it was actually larger than my last battery. I have a Harley and the battery box required the battery to be have very specific dimensions. This one is a bit too large and it was a tight fit to get it into the battery box. That turned out to be the least of the challenges on the install. Attaching the cables to the battery terminals involves inserting the supplied nuts into the terminal slots. The gap on the battery terminals where the nuts go in is so large that the nut would fall out or if I managed to keep it from falling out, the nut would get push to the back side of the slot and the terminal screw could not reach it. After about 20 mins trying to get them to stay in I knew I had to come up with another solution. It was obvious that I needed something that I could use as a shim to hold the nut toward the front of the terminal slot and prevent it from falling out when putting in the screw. After considering several materials I spotted a styrofoam cup. I grabbed some scissors and cut a strip out then folded it to fit tightly into the terminal slot. With that in place I inserted the nut which now is held tightly in place and at the front of the terminal slot. The styrofoam worked well because if easily formed around the nut to hold it in place. I should point out that I used the nuts from the previous battery because they were actually rectangular in shape as they should be and the supplied were hex nuts. Very poorly thought out. The battery is new and starts the bike well. I can't speak to the longevity of the battery because I have not had it long enough. I won't be purchasing this battery again regardless. The fitment problem and installation issues it's not worth it.
