Heat is harder on a battery than cold is. Cold weather gets the blame because that is when a weak battery finally refuses to start the car, but the damage usually happened months earlier, in July. Under the hood in Central Florida a battery spends most of the year at temperatures that speed up the chemistry inside it, evaporate fluid out of the cells, and build sulfate on the plates. Sulfate is the chalky layer that keeps a battery from accepting and holding a full charge. So a battery down here can look fine on a mild morning and still be well past its useful life.
Testing tells us more than age does. We load test the battery and watch what the voltage actually does under demand, check state of charge, and see how it behaves with the engine running and after the car has been sitting. Then we pull the terminals, clean the posts and clamps, and look at the white or green crust that quietly adds resistance to every circuit the battery feeds. A loose or corroded connection can act exactly like a dead battery, and it costs nothing to rule out.
Here is the part that saves people money. A battery that keeps dying is often not the problem. If the charging system is not putting voltage back in, a brand new battery will die the same way in a few weeks. If something in the car is drawing current after you shut it off, same result. So before we sell you a battery, we check charging output and look for a drain. Sometimes the answer really is a battery. Sometimes it is a charging or wiring issue, and a new battery would only have reset the clock on the same complaint. Either way you get the test numbers and the inspection photos on your phone, so you can see what we saw.
The technician ran a diagnostic parasitic draw check of multiple modules, fuses, relays and harness as a digital inspection at the Lake Wales shop.

Read the full jobWe stopped in with my 2021 Jeep Wrangler because my AC wasn’t working. They took it back almost immediately, diagnosed it for $140, and gave us two estimates on what it will cost to repair. We’ve decided to bring it back next week to have the work done by them as they offer a 3 year/ 36k warranty, and the man was very helpful and extremely knowledgeable. I wish we would have taken my husband’s Cadillac there before we ended up trading it in due too to many expensive issues.

Johnny’s in Lake Wales was great!! Sahra listened to what was going on with the Jeep and the technicians were able to diagnose the problem and fix it. We will definitely go back there!! Hopefully only for routine maintenance.

I had my 2014 Jeep grand Cherokee in for an oil leak. Jerry quickly diagnosed the problem. Scheduled appointment for the following day. I dropped the Jeep off with Kevin and Sarah stated they would give me an update later that day. I received a call that my jeep was finished. I came in and when I picked up the jeep, the bill was a little lower than they had originally quoted. It was a great experience for me and I would definitely recommend them to all my friends!

My Jeep started acting up on Tuesday 12/05/23 on my way home from work almost got stranded out in the middle of nowhere. Called Johns the next morning and they got me in on Thursday 12/07/23 first thing. I got a call back with in a couple of hours with a text detailed report with pictures showing what was wrong. Also gave me a report as to what should be done over the next 3-6 months to avoid huge repair cost on the future. As my Jeep is getting close to 100.000 miles. Once additional work completed the tech said I will have a great running safe vehicle. The problem that almost got Mr stranded was key SAFETY things the dealership missed on its 120 point inspection when I took it in for a oil change 2 weeks ago. At Nissan Hill and previous break work done at Tuffy's in July, They missed rear bearings we shot. I will no longer take my vehicles to a dealerships or other place, I will only be dealing with Johnny's in Lake Wales from now on..for my Jeep and my wife Nissan.. Once work is completed on my Jeep we taking my Wife Nissan in for inspection to see what the dealership may have missed on her car so we don't run in to this issue of things missed and the end up with huge repair bill in the thousands. The very nice young lady at the front desk. Gave me single rose for me to give my wife. To help her feel better because of other places not doing there job this a costly repairs. My wife just lite up and got very teary eyed and smiled. They make you feel like family the moment you walk in the door. They don't rush you and help you find a way to do repairs in states as long they (Johnny's) knows the vehicle will be safe on the road.. And with the distance I drive for work. The tech said for your safety these list of things has to be done others we could probably do in stages but not to far apart. Jeff & Jennifer.
