Summer heat cooks the internals, winter cold cripples cold-cranking amps, and short trips never fully recharge it. Most passenger-car batteries last 3–5 years, and by year four you’re on borrowed time. ![Digital battery load tester displaying cold-cranking-amps reading](/images/misc/digital-battery-load-tester-attached-to-car-batter.webp) **Every visit to our New Britain shop includes a free battery load test.** We use a digital tester that measures actual cold-cranking amps against the spec printed on your battery — a real load test, not a guess based on voltage alone. If your battery is weak, we’ll show you the number and let you decide. ### Won’t Start? We Diagnose the Real Cause A car that won’t start could be the battery, the alternator, the starter, a bad connection, or even a parasitic draw slowly killing your battery overnight. We test all of it before recommending a repair — you don’t want to buy a new battery only to find out the alternator was the real problem. Our diagnostic tools: - Digital battery load tester (with CCA readout) - Charging system tester (alternator output under load) - Multimeter for parasitic draw measurement - Professional OBD-II scan tool for trouble codes ### Quality Batteries, Fair Prices We install Interstate, Duralast, and other quality-brand batteries with **real warranties** — not house brands with fine-print exclusions. Prices vary by vehicle size and battery type; we’ll give you a firm quote after testing. Old battery core credit applied at the counter. Transparent Pricing ## Battery & Electrical Pricing Fair, honest pricing with no hidden fees. Ask about current coupons. Starting at Per service — free battery test Free battery load test with every visit. Interstate and Duralast batteries in stock.

Berlin FAQ ## Battery & Electrical FAQs ### How much does a car battery cost at your shop? expand\_more Depends on your vehicle's battery size and type (standard flooded vs AGM). Interstate and Duralast batteries range from around $130 to $250 installed for most passenger cars. Free load test first — sometimes the battery is fine and the problem is elsewhere. ### How do I know if my battery or alternator is the problem? expand\_more A dying battery cranks slowly, especially in the cold, and may need frequent jumps. An alternator problem shows up as dim lights while driving, dashboard battery warning, or a fresh battery that keeps dying. We test both to be sure. ### Do you charge for battery testing? expand\_more No. Battery load testing is free at our New Britain shop. Bring it in any time, especially before Connecticut winter starts. ### How long do car batteries last? expand\_more Typically 3–5 years in Connecticut's climate. Extreme heat and deep discharges shorten that. If your battery is 4+ years old, get it tested annually — even before it fails. ### Can you diagnose electrical problems beyond the battery? expand\_more Yes. We use professional OBD-II scan tools and multimeters to trace parasitic draws, faulty ground connections, alternator diode failures, and starter solenoid issues. Real diagnostics, no guesswork.
