Impressed from the start
Very happy with service and battery The shipping and delivery response was amazing keep up the great work!
Exactly as promised
The team at BRS answered the questions I had prior to the purchase, ordering was quick and easy, received a confirmation minutes after purchasing( it was hilarious Andy) so coupled with the quick delivery, it was an enjoyable experience.
Performing great.
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. I bought the BRS smart trickle charger with this battery and will use it on the off season. We’ll see how it does long term next spring. I’m not too worried though, battery has a two year warranty.
Big thanks to the whole crew
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.
Pleasant experience from the start!
Read some good reviews online regarding the batteries and found exactly what I was looking for. Shipping was prompt and communication was great. Box was packed perfectly and well protected. The owner even emailed and thanked me for my order! I will definitely be returning and will be telling others about BRS!
Order received on time.
Order received on time. This is the third time I used BRS EXCELLENT service. Will recommend this it to all my friends.
Stayed in touch with me
highly recommend BRS Battery. The company stayed in touch with me during the purchase process and during delivery. The battery was received quicker than I thought. It was fully charged and I installed it right after delivery.
Excellent product
Excellent product, quick delivery. With the recent ice storm I had to fuel a generator for 10 Days. This fuel pump made it so much easier. No lifting, no spilling!
100% recommend this company.
100% recommend this company. I had an issue with the unit I ordered, sent an email on a Saturday not expecting to hear a response till the following week. Was totally PLEASED & SURPRISED to receive a response that evening, stating a new unit would be shipped (at no expense to me) Monday
