The starter and the alternator are two different parts that get blamed on "the battery." The starter is what cranks the engine when you turn the key; the alternator is what keeps the battery charged while you drive. Replacing the wrong one costs money and fixes nothing. We come to you, test which it is, and replace the right one.
Signs you may recognize
- You turn the key and get one loud click — that points to the starter.
- The battery drains even though it's new — that points to the alternator.
- The battery light comes on while you're driving.
- Lights go dim or the car dies while running.
- It starts sometimes and not others, with no pattern.
How we help
We test first, we don't swap blindly. We measure the charging system to see if the alternator is delivering what it should, and we check the starter and its connections. That separates the three suspects — battery, starter, alternator — so you pay for the part that's actually failing.
Once we confirm which it is, we replace it at your home or job and leave the car charging and cranking properly before we go. If the battery got damaged by an alternator that over- or under-charged it, we show you and tie it into our battery replacement.
We cover San Antonio and the nearby communities in Bexar County via Loop 410, 1604, I-10, and I-35.
Frequently asked questions
How do you know if it's the starter or the alternator?
We test them separately on the spot: the starter by how the engine cranks, the alternator by measuring the charging system. We don't guess.
I replaced the battery and it's still the same. What's left?
It often points to the alternator, but we confirm it by measuring the charging system. If it is not charging, the new battery will drain too.
Do you replace it in the same visit?
When we confirm the part and have it for your model, often yes, on the spot.
How soon can you get there?
Depends on your area and the schedule — often same-day when available.
