Maintenance and lifespan

Typical lifespan

Lead-acid starting batteries commonly last around 3 to 5 years. Heat, frequent short trips, deep discharges and high electrical loads shorten their life.

Signs of wear

  • Slow or laboured cranking
  • Battery or charging warning on the dashboard
  • Start-stop working less often
  • Corrosion on the terminals
  • Swollen or leaking case
  • Needing jump starts

Basic checks

  • Measure the rest voltage with a multimeter after the vehicle has been off for several hours
  • Ask a workshop for a load or conductance test
  • Clean and tighten the terminals
  • Check that the hold-down clamp is secure
  • Have the charging system tested if the battery keeps going flat

Safety

  • Wear eye protection and gloves
  • Keep sparks and flames away: batteries can release hydrogen
  • Disconnect the negative terminal first and reconnect it last
  • Never short the terminals with tools
  • Recycle the old battery at an authorised collection point

Flooded Serviceable flooded batteries: check the electrolyte level only if the caps can be removed, and top up with distilled water only.

General guidance. Always follow the battery and vehicle manufacturer instructions.

Frequently asked questions

Answers built from the fictitious demo record. Not valid for purchases.

Which battery does the Caterpillar 320 Cat C4.4 need?

The data on this page lists 2 × Demo Battery Co. DMO-4D-HD (Flooded, 12 V, 180 Ah, 1000 CCA (SAE)). Status: Demo (fictitious).

What size or group is it?

BCI 4D. Case dimensions: 527 × 222 × 250 mm.

How many cold cranking amps (CCA) does it need?

The listed battery is rated 1000 A under the SAE standard. Choose an equal or higher value measured under the same standard.

How many batteries does it use?

2 batteries connected in series. Replace all of them at the same time.

Do I need AGM or EFB?

The listed battery uses Flooded technology. Do not replace an AGM battery with EFB or conventional flooded.

Where is the battery installed?

Battery box, right side.

Does the new battery need to be registered or coded?

Some vehicles with battery monitoring require registering the new battery with a diagnostic tool. Check the owner's manual.

What happens if I install the wrong battery?

It may not fit the tray or reach the cables, start-stop and charging may not work correctly, and the battery or electrical system can be damaged. Match size, terminals, technology and ratings.
