    Although i never actually tried the Battery out, it seemed of good quality like it would last a long time. My only issue is in the description. This batt was supposed to fit my bike but it was a half inch too tall. But both the customer and the normal service were great. Speedy delivery. Packageing was spot on. As for returning it, couldnt ask for any better, they refunded my account before i even had a chance to send the battery back.

    There was a mix up of the ship to address when I ordered this. I spoke to a customer service manager, Leo, asking his help correcting the wrong ship to address. He handled it, it was received at the corrected location, Leo did a great job of following through. Based on this, I would highly recommend this seller.

  • U1 12v 35ah batteries

    The last ones I ordered were also Sigmas Tek U1 12v 35ah batteries. The old ones went over 2 weeks on a charge and these replacement go for under a week on a charge. They were both used for the same distance between charges. Also, and more IMPORTANTLY, the older Sigmas Tek batteries lasted 4 YEARS before they needed to be replaced.
