United StatesPoor decision not to honor price over $20.00. Felt like I was dealing with a scammer. Left a bad taste, also order was late via fedex. poor communication.
On your original order, you purchased 3 bigger more expensive batteries which we did $20 off per battery. When you called back, you wanted to order 1 smaller less expensive battery, which we offered $10 off on. Shipping one battery can be expensive and we typically don't do discounts on single batteries because of this. However, since you had purchased before, we did offer you $10 off. The percentage of discount was the same as before because of the difference in pricing in the batteries you wanted. It is unfair to call us scammers, when you did receive your product at a fair price. Not to mention it was fresh product that is hard to find these days. As far as Fed Ex delaying your package, that is out of our control. With the pandemic, shipping times and have been greatly affected. We did ship your order out right away.
United StatesThe NorthStar NSB-AGM-31M was a hard battery to find with the current supply chain issues of marine products. This is a great battery and their price was fair with the shipping included.
United StatesOrdered this battery on a Sunday and Batteryguys had it ship the next day.
United StatesFinally got them installed in the Safari Serengeti motorhome and it cranks over really fast with these 2 new batteries. Items were packed well in a nice thick box cardboard box with good protective support, and shipping was fast via FedEx. Satisfied with the purchase.
United StatesI have only been off shore in my boat with my new NorthStar battery installed one time, but it performed flawlessly! The Battery Guys had the best price on this battery and with free shipping! It was shipped on the first business day and I received it four days later. Fantastic price and service.
