Craigslist Mobile Mechanic ? Recommendations?

I would ask if he has a shop and can you visit. Find out if he's done this before or is he just selling a junk yard battery that he has repaired a cell on. References should be personally checked. Otherwise why not go to a battery shop that has experience to stand behind a reasonable price and a shorter but believable warranty. Also Dorman is selling replacement batteries.

 

I removed replaced a bad cell and cleaned the contacts and installed my battery in less then 3 hours following videos on you tube and a $35 cell from e bay Id never trust a craigs list guy to work on prius...they don't have the equipment or training...and just walk away when they screw something up....just my two cents on backyard mechanics

 

Hello All, I have had a situation with my 2007 Prius high voltage battery and i used a local mobile mechanic by the name of EV Hybrid Tech, they charged me $800 for lifetime warranty battery replacement, i have tried to replace bad cells with other mechanics but i ended up paying the same amount of money and it only lasted about 6 months, my understanding talking to those guys that once you have a bad cell, which isn't easy to find using multi-meter only, it's probably an indicator for the overall health of the pack.
i went into deep technical explanation with Sam and Sherief who posses a Bachelor degree in mechanical engineering and have had certificates in both Electric vehicles and Hybrid systems. basically every time you have a bad cell, it means there is a block (2 cells) that went bad, when such even occurs, the Inverter overload the battery to try to get this bad cell to stay within the acceptable range of voltage reading, which overload mostly the rest of the cells, so when you have bad block, it's probably more than one set of cells, the other important issue is the sensing element of the battery pack, it goes bad sometimes and causes similar effect of bad cell, only that harness needs to be repaired or replaced for less.
one of the most important things is you have to use a good mechanic, other wise you end up paying as much as you would to a dealer.
those guys are highly trained, professional, honest and knowledgeable as well as approved mobile mechanics by the BAR Bureau of Automotive Repair, they issue invoices with clear warranty details, i recommend them to Los Angeles residence.
