Vanesa was very helpful through the purchase process and shipping was timely and the batteries arrived in great condition. All installed and working well….. Only thing you could have done better would be to carry them down to our boat for me…. 🙂

Very easy to work with and I look forward to seeing how the Crown batteries perform over the long haul. I have used Trojan T – 105’s for our battery bank and got 10 1/2 years out of the first set but only 7 years out of the second set.

The experience with Online Battery Sales is great. The communications and purchase process is easy and the prices are great. I’m a repeat customer and plan to continue.
