I have had only good experience with them. Over the years Twice I have had them rebuild and repair alternator issues; I have found their quality to be exceptional and their prices fair. My last encounter was to investigate an intermittent electrical failure. They tracked the issue down to a newly installed battery cable that was both not secured to the battery box and the positive terminal was very loose. They took pity on me. The did not charge me for their troubleshooting and repair. I will definitely go to them first for any battery and charging issue.
