I have been Yuasa batteries with great success in motorcycles since 1966, I have tried others but they did not deliver for the long haul.
I have found Yuasa easy to deal with, they publish great info pamphlets and now most of the info is available on their website for downloading. I have always been pleased with their customer service and especially the product.
Nothing against Westco, I just have used many Yuasa batteries over the years. I did use a Westco battery in a Miata once, traded the car after two years so it really was not tested. It just happened to be the one I could get the quickest when I needed a replacement.
I've been using Deka batteries (usually available at Batteries Plus) since they are the manufacturer for OEM Harley batteries. They have Goldwing applications. I usually pay $20-30 less than HD dealer prices for the same battery. Made in the USA, I believe.
My original OEM Yuasa was installed in the Wing in October of 2004. The bike only had 3061. miles on it when I purchased it used in March of 09; mostly sat in a garage unused and the battery on a tender "sometimes". I have put 70k on the bike since then, and ride all year round. My GL1800 is parked outside every night, and ridden most every day whether it's 7-degrees or 104-degrees.
My original Yuasa has never failed to crank strong and fast. This winter was so long and tough... the bike was actually frozen on a couple of occasions at my 6am commute. Yet, the battery just keeps on firing... instant start-ups! I have no plans to pre-emtively change it out either.
WHY WOULD I CONSIDER ANOTHER BRAND/model for the GL1800? :bow:
My Yuasa batteries averaged 9 years. I did have one that failed in only 5 years. It sat through several cold winters not on a tender, sometimes for two months at a time. When I get results like that I would never bother experimenting with another brand. If you search you can find Yuasa at very reasonable prices too.
Yuasa all the way. It is OEM for a reason... reliability. Yes, on occasion they fail. Happened to me many years ago, but the thing was 4 years old. Someone can practice or experiment with other brands, but I'm going with what is tried and true. Case closed.
