For approx 10 years My wife and I both bought batteries for scooters and a wheel Chair. Very good prices and friendly staff. I even wrote 5 star reviews BUT I finally had a problem, they were still friendly telling me a test with photo they needed to replace ( as it turned out only one of 2 batteries were defective) they sent them about 10 days prior and then they wanted another pictured test and then they suggested another. I finally gave up. Even after charging overnight battery status indicator on chair would go from green lights to only yellow lights after 45minutes of use. Over the years on two previous sets of batteries I could run for 1 3/4 hours and still have one green light left and batteries were 1 to 2 years old. So go ahead buy from this company as you save money but do not expect any warranty replacement when you deal with Battery Sharks. I will attach copy of invoice slip to show I'm a customer, and who knows when they see my customer and order ID maybe they will have change of heart and if so I will be happy to give another good review :).
