Cincinnati Auto Repair in Cincinnati replaces car batteries only after testing the battery, alternator and starter together, because a new battery in a car with a weak alternator goes flat again within days. Call (513) 666-5717 with the symptom, the vehicle's year and model, and when the battery was last changed.
A car that clicks and won't crank is not automatically a battery problem. The battery, the alternator and the starter each need to be tested before anyone sells you a replacement, because a new battery bolted into a car with a failing charging system will be dead again in a few days and you will have paid twice.
Cincinnati Auto Repair handles battery replacement for Cincinnati drivers as part of electrical diagnosis at 4436 Vine St in Cincinnati. Give the year, make and model when you call, so the battery size and terminal layout can be confirmed before you arrive.
How do I tell a dead battery from a bad alternator?
Jump the car and watch what happens next. An old battery that simply gave out will usually let the car run normally once it is started. A failing alternator lets the car start on the jump, then stall minutes later, often with dim headlights and a battery light on the dash.
Slow, labored cranking on a cold morning points to the battery. A single loud click with bright dash lights points more toward the starter or a bad connection at the terminals.
What should a battery replacement quote spell out?
Ask for the battery size group, the cold-cranking rating, the warranty term, and whether a core charge is included in the number. Ask whether the terminals and cable ends are cleaned, since corrosion there can mimic a weak battery.
- Whether the charging system is tested before and after the swap
- Whether your vehicle needs the new battery registered with its computer, which some newer models require
- The date code on the battery being installed
Why does a brand-new battery keep draining overnight?
That is a parasitic drain: something is drawing current after the car is switched off. Usual suspects are an aftermarket stereo or alarm, a stuck relay, or a light that never turns off in the trunk or glovebox. Finding it means measuring current draw with the car asleep and pulling fuses one at a time until the number drops.
That is electrical diagnosis rather than a battery sale, so expect it to be quoted separately.
How long does a car battery last?
It varies with the battery, the car's electrical load and how often you take short trips. If yours is several years old and cranking has slowed, have it load-tested rather than waiting for it to strand you.
Can I just get a jump and keep driving?
A jump gets you started, nothing more. If the alternator is the problem, the car can die again on the road, so get the charging system tested the same day.
What do I need to tell the shop when I call?
Give the year, make, model and engine, how the car behaves when it fails to start, and roughly when the battery was last replaced. That lets the shop line up the right part and plan the testing.
