Our Super Charging ProcessLearn more

We don’t rush batteries out the door. We do five things so it works when you turn the key:

Fill with 1.265 SG electrolyte to spec.
Let it soak for full glass-mat absorption.
Slow, high-frequency forming charge (~900 mA) to form the plates.
Rest and verify it holds 12.6–12.8V.
Final QC. Ships ready to install.

Pro Tip: Keeping the battery on a smart maintainer after rides helps it last 8–12 years.

FAQAnswers

Do I need to charge it before installing?

No. It ships charged and ready.

How does the maintainer help?

Machines sit. The BRS612 keeps the battery topped so it starts on the first push and helps maximize lifespan.

Where’s my model number?

On the face label (e.g., YTX9B-BS). This BRS9B-BS replaces that size.

How is this different from a cheap battery?

We soak, form, and test each one. No acid splash-and-dash. That’s why it cranks harder and holds charge longer.

How cold will it work?

Our Super Charged AGM performs in tough weather. For maximum reliability in winter, keep the battery on the maintainer when parked.

STORE REVIEWS

So far this battery is performing great. My 10 year old H-D AGM battery was giving me trouble, would not hold charge for more than a couple of days, then it would not start the bike. Since installing this battery a couple of weeks ago, I have not had to plug the trickler in and the bike turns over like a champ and starts every time.

Mike Steak

Ordered a battery for a snowmobile and a fuel transfer pump. Both items arrived in record time (ordered on a Saturday, arrived on Tuesday). I am extremely happy with both products. Battery has tons of cranking amps and fuel transfer pump with shut off sensor works fantastic. I would highly recommend both products and will making more purchases from BRS Battery in the future.

Had my eye on this pumpmatic for over a year and finally bought it-used it last week at my cabin in the woods and it’s a total game changer!! Loved it and it worked better than I could have hoped for. Gassing up the generator was so easy and being able to fill the boat tank was so easy and no spills or lifting!! If you are on the fence it’s worth every penny!!

BRS Battery Ltd. is a fantastic company. ThePumpMatic Super Long Gas Pump w/ 12 Ft Hose is a life changer for me. I am 78 years old and my gas cans I use for my riding mower are on the floor in my garage. They are 5 gallon containers and are to heavy for me to pick up and pour fuel into any of my gas engines or vehicle. The 12 ft hose is great for this situation and safe. BRS is my go to gas can pump needs. Thank You KW, USA

Battery arrived to my door within a couple days at the most. Appeared to be fully charged, and in 100% state of health according to my battery tester. Incredible customer service from the moment I requested information on the battery, including now. Battery seems strong, I've only started the ATV a handful of times, but it works, and when I put it on the trickle charger, its fully charged again in minutes. I'm glad I did an internet search, and found this company and their battery. Looking forward to some cold starts in the winter.

Michael Linschoten

So again I went with BRS as my new ATV Battery because the one I bought for my side by side worked so well why not deal with local. The battery comes pre-charged ready for install not like them other batteries.
The price was about $12 cheaper then Yuasa and was delivered to my door in less than 32 hrs can't get better than that and like I say its keeping our money in Canada/Ontario.
Big thanks to the whole crew for making and delivering these awesome batteries.
