Battery YUASA or OEM BMW

buy original YUASA . it is the best choice.

Can’t attest for AJC but Yuasa is a quality driven company that is widely used as original equipment. If your usage is not critical or if you trust the recommendation of battery clerk then you can go with the cheaper battery, otherwise I strongly recommend Yuasa

Yuasa YTX14AH-BS is the OEM high capacity battery. I don't think there is a better one you can buy, even spending more money.

For about a month I have owned a 2016 REx whose 60 Ah battery is supposed to get 72 miles. This week I fully charged it and have been commuting four four days without topping up. Today the REx kicked in with the trip meter at 73.3 miles. This was a mixture of city traffic jams and short bursts on the carriageway, mostly with the air con on and mostly in Comfort mode. So I'm pretty pleased.

Go to Halfords, use their parts search, buy a Yuasa for fifty quid and ride away into the sunset mate.

My last Yuasa outlived the bike!

Ive been really happy with my yuasa battery, its only stuttered to start once this winter(and unfortunately I dont have a garage here so theyve been outside pets for the time being), and that was after sitting for a week waiting for ice to melt, otherwise riding nearly daily and once a month or so conncting it to my battery tender.

In my experience Yuasa batteries are the best, I had a Yuasa factory sealed maintenance free battery last eight years in my FZR1000.

Yuasa batteries are great. I would however recommend either getting the Yuasa charger/tender (available on amazon) or a battery tender to go with it. My commutes were too short (14 mi a day) to charge the battery and after a year or so of riding like that it lost its charge.

I'm using a Yuasa with a 4 year warranty. The optima yellow is good but not worth 3 and half times the price for twice the life span of a normal battery unless you plan on deep discharging it a few times. I just think they're a little over priced for what you get.

Put a Yuasa in my Street triple and it lasted 1.5 years almost exactly. Would keep it on the tender in cold months every so often, never killed it or discharged it, and still died which was disappointing for the price and the “OEM” brand.
