2010 Accord Original Factory Battery Specs
When new in 2010, the Honda Accord was equipped from the factory with following battery specifications:
- Group Size: 34/78
- Voltage: 12V
- Cold Cranking Amps: 500-600 CCA
- Capacity: 45-60 Ah (amp-hours)
- Type: Lead-acid, sealed and maintenance-free
- Terminals: Top post
- Location: Front right of engine bay
- Manufacturer: Typically Exide, Interstate or Johnson Controls
Adhering closely to these specs when the time comes for replacement is recommended to maintain proper electrical operation.
Signs Your Battery is Due for Replacement
How can you tell when the original battery in your 2010 Accord is reaching end of life and due for a swap? Watch for these common warning signs:
- Slow cranking when starting, requiring multiple tries
- Dimming headlights upon startup
- Battery warning light activating on the dash
- Reduced radio/electronics performance
- Failure to hold a charge over extended periods
- Corrosion or damage on the case or terminals
- Cracked or bulging battery casing
- Over 5 years old existing in hot climates
Upon experiencing these symptoms, have your Accord’s battery tested to determine if a replacement is required.
Buying the Right New Replacement Battery
When selecting a replacement battery for a 2010 Honda Accord, ensure to choose a battery meeting the factory specifications for optimal performance and fit, including:
- 34/78 group size
- 12V voltage rating
- 500-600 CCA for sufficient starting power
- 45-60 Ah capacity range
- Proper top side terminal configuration
- Same physical dimensions as original
Purchase from reputable brands such as Interstate Batteries, AC Delco or Optima to get a quality battery backed by a strong warranty. Avoid cheap no-name batteries that won’t last.
Steps for DIY Removal and Install
Installing a new battery in a 2010 Accord takes less than an hour and requires only basic tools. Follow these key steps for a DIY battery swap:
- Disconnect negative terminal first then positive terminal
- Release the hold-down clamp or J-hook from the battery mount
- Lift out old battery from the tray and dispose properly
- Clean corrosion from the tray, clamps and terminals
- Lower in the new battery, ensuring proper positioning
- Securely mount the new battery and reinstall clamps
- Reconnect positive cable first, then negative cable
- Verify electronics turn on and engine starts correctly
Always wear eye protection and avoid touching eyes while handling batteries. Take old batteries to recycling centers.
Signs of a Failing New Replacement
Even shortly after installation, some signs your new replacement Accord battery may be defective or fail prematurely include:
- Poor starting ability immediately after install
- Frequent need to recharge the battery
- Continued loss of charge when parked
- Persistent battery warning light after replacement
- Low voltage readings from a voltmeter
- Extremely short lifespan before failure
Faulty new batteries under warranty can typically be returned to the parts store for a free replacement.
Steps to Maximize New Battery Life
To get the most years of service from your new Accord replacement battery:
- Maintain a full charge by regular driving or charging if stored
- Keep it securely mounted to minimize vibration
- Clean any corrosive buildup from terminals
- Avoid overcharging by unplugging accessories when running
- Check voltage monthly and recharge as needed
- Park in covered areas to protect from extreme heat
- Have the charging system tested annually
Proper care can potentially double the lifespan of a new battery.
Alternatives to Typical Lead-Acid Batteries
For even longer life than lead-acid offers, some alternatives to consider are:
1. AGM Batteries
Absorbent glass mat batteries provide increased cold cranking power and lifespan over standard batteries.
2. Lithium Ion Batteries
Though pricey, lithium batteries are very lightweight with a typical 10-year service life.
3. Hybrid Batteries
Hybrid battery packs are rechargeable by the car but pricy when replacement is needed.
Discuss alternative battery technologies with your Honda service advisor to see if one makes sense for your needs and budget.
Steps for Safely Jump Starting a Dead Battery
Despite your best efforts, you may still occasionally find your 2010 Accord’s battery dead due to leaving lights on or other mishaps. Jump starting it properly gets you back on the road quickly:
- Position the donor car so cables easily reach both cars
- Turn off all electronics in both vehicles
- Clamp red cable to Accord positive terminal first
- Attach red clamp to donor battery positive next
- Clamp black cable to donor battery negative terminal
- Complete black cable connection to Accord negative last
- Start donor car and let idle for a few minutes
- Try starting the Accord, keeping donor car running
- Once started, unclamp cables in exact reverse order
- Keep Accord idling for 30 mins to recharge before shutting off
Observe polarity and work safely to avoid battery explosions or electrical damage. Call for professional assistance if unsure.
When to Call a Tow Truck
While a jump may resurrect your flat Accord battery occasionally, calling a tow truck is wise in situations like:
- Battery is extremely old and due for replacement
- Terminals are excessively corroded or damaged
- Battery case is cracked, split or bulging
- A jump start cannot get the car running
- Issues persist immediately after installing a new battery
- Specialty equipment like a load tester is needed
- The battery fails in an unsafe location
Let experienced automotive technicians safely evaluate or replace the battery back at the shop as needed. Don’t strand yourself unnecessarily by ignoring the signs of a dying battery.
Preventing Corrosion on Terminals
To help avoid battery terminal corrosion buildup on your Accord:
- Tighten connections securely to reduce seepage
- Use dielectric grease on terminals during install
- Check for white or blue crust monthly
- Clean any corrosion immediately with a wire brush
- Rinse terminals with diluted baking soda solution
- Apply an anti-corrosion spray after cleaning
Stopping corrosion early keeps your battery operating at peak efficiency for longer.
Disposing of Used Batteries Properly
When your old Accord battery finally dies, recycling it responsibly is important:
- Wear gloves and eye protection when handling
- Tape the posts to prevent short circuits
- Take to a battery retailer or recycling center
- Never toss old batteries in normal trash
- Consider exchanging old for a discount on new
Proper battery disposal keeps acids and heavy metals out of landfills.
Regular System Inspections are Key
To maximize battery lifespan on your 2010 Honda Accord, having the electrical system inspected annually is recommended:
- Check charging voltage and draw
- Inspect cables and connections
- Load test to determine cranking power
- Assess starting and charging system parts
- Scan for computer fault codes
Proactively identifying impending electrical issues provides opportunity for repairs before battery failure gets stranded.
While often overlooked, maintaining your 2010 Honda Accord’s battery diligently and replacing it promptly when needed provides reliable starting and power for electronics. Avoid getting left with a dead battery by monitoring age, watching for warning signs, properly jump starting and having the charging system inspected routinely. With some basic knowledge and preventative care, your Accord’s battery will keep you cruising for years down the road.
