My next battery will be an OEM Yuasa. I used the first one from 07 til 2013 and it never failed I just replaced it because it was old and didn't want to find out just how long it would last.
You probably already know this but powersports Motorcross battery is the same as OEM Yuasa, just different lable. Made in the same USA factory in Philly.
I bought Powersports Motorcross 310 CCA for $89. Fingers crossed
First, let's look at Yuasa:
Yuasa (pronounced "You-Aw-Sah" is almost a household name when it comes to motorcycle batteries. Since 1979, Yuasa has been manufacturing OEM Batteries in the USA for new motorcycles, ATVs, and other power sports applications. Although Yuasa has factories in Japan and Taiwan, they manufacture their large capacity powersports batteries in Laureldale, Pennsylvania. They offer a wide selection of both conventional wet-cel and sealed AGM batteries. These are good batteries, hands down.
So, what about Motocross?
Believe it or not, Motocross is manufactured in the same factory, the same assembly process, at the same time as the Yuasa. The only difference is the label applied at the end of the manufacturing process. Motocross came about as a way for Yuasa to enter the ever growing aftermarket, without disrupting their already established brick and mortar new bike dealerships. This allows them access to a much broader market share, at a much more reasonable price point.
So, basically, when you buy a Motorcross replacement battery, you're really getting a Yuasa.
There you have it. This round of Versus is really about shedding some light on a common misconception. Motorcross is not better than Yuasa when it comes to performance. They are just as good. However, they are the winners when it comes to a better deal. Buying a replacement battery from Yuasa will typically be marked up in price because they sell directly to bike manufacturers. But the Motocross is marketed as the affordable alternative replacement battery.
To add to that Deka/Easternpenn battery mfg has been in battery mfg biz since 1955 so they have just as much or more exprience in the battery mfg biz as yuasa does with both mfgs having a good rep.
Deka has such a good engineering rep when it comes to batteries that the federal government is investing in East Penn, which has 90 warehouses across America and facilities that make battery accessories, wire and cable.
East Penn's reputation for innovation and environmental friendliness, landed it a $32.5 million U.S. Department of Energy grant in August to develop new battery technology for electric hybrid vehicles.
Also,the 500 & 375cca mant free agm factory activated batteries i posted on here in fact mfg in the USA per main
mfg website so they are not mfg in china that can be questionable at times.
I have been wrenching bikes cars for over 4 decades and know 1st hand deka bike car batteries are a good quality reliable battery just as good as Yuasa.
In over 4 decades 1st hand exp installing new batteries in bikes and cars have i run into a few Yuasa & Deka batteries that were either defective when bought new and or expired before they should have in both cases .
And Yuasa that many people use as a benchmark isnt perfect either because have had them fail on me personally leaving me stranded a couple times not to mention people brining bikes to me to work on that wont start with dead/defective yuasa batteries that wee only 1-1.5 yrs old with a bad cell etc.
But in the long run i have found both mfgs (yuasa & deka) to be approx = when talking quality with the deka agm maint free 310cca bike battery being 1 of if not the best value for money spent ($89)vs srv'c life with yuasa's factory activated mant free agm 310cca battery costing on avg $30-35+ more for not any better perf or srvc life oin avg for more money.
But time will tell how these 375 & 500cca batteries i posted on work out when it comes to quality & srvc life.
Now if those batteries work out to be good & reliable with long srvc life (at least 4-5yrs) they would also be great replacement batteries for the R* when it comes to cost vs starting power & srv'c life.
