RAM 2500 AGM Battery or Lead-Acid Battery?

A lead-acid battery performs poorly in very cold conditions, repeated power failures shorten the life of the battery in the RAM 2500. For these reasons, many RAM 2500 owners like to switch to AGM batteries. If you want a new replacement battery for your Acura MD or want to upgrade to a better quality battery for your Acura MD, switching to an AGM battery can be a great option. Not only are these batteries sealed, but they also have excellent performance.

Why is it better to use AGM Batteries for the RAM 2500?

AGM batteries are better able to cope with the increased stresses that the RAM 2500 driver constantly faces. The main problem with conventional batteries is their shorter lifespan due to the high electrical stress your RAM 2500 is subjected to.

The AGM batteries in your RAM 2500 can discharge without being damaged. Because the plates and gaskets in AGM batteries are much tighter against each other, the casing is sealed, AGM batteries for your RAM 2500 are more resistant to vibration and off-road shock.

The functions that the battery performs in the RAM 2500:

  • Provides power to the starter in the RAM 2500
  • When the RAM 2500 engine is turned off, the battery powers auxiliary electrical equipment
  • Powers emergency systems when the engine is off in the RAM 2500
  • Is an auxiliary power source in the RAM 2500 when operating devices with high current consumption

How do I choose a battery for my RAM 2500?

  1. Study the RAM 2500 owner’s manual, it will indicate the battery requirements
  2. Determine which battery is currently installed on your RAM 2500 (capacity, size, starting current)
  3. Select a battery for your RAM 2500 based on our review

Key criteria for choosing a battery for your RAM 2500:

  • Capacity. For diesel cars and SUVs with a large engine capacity, we recommend using batteries with a capacity of 70-90 Ah. Stick to the RAM 2500 manufacturer’s recommendations and use a battery with the rated capacity for the RAM 2500.
  • Starting current. The maximum amount of current a battery can deliver in a short period of time (10 to 30 seconds). Cold Cranking Amps (CCA) – The cold cranking current of a starter battery. For RAM 2500, it is recommended to use a battery with CCA between 700 and 800 A. We recommend choosing a battery for the RAM 2500 with higher starting current ratings. Such batteries are more expensive, but they allow you to start the engine RAM 2500 even in severe frost.
  • Dimensions. Pay attention to the size of the battery pad in your RAM 2500.

How do I check the battery in my RAM 2500?

You can check the battery in your RAM 2500 in several ways: with a multimeter, a load fork, and a starting current tester.

The RAM 2500 battery terminal voltage should be at least 12.5 volts after 10 to 12 hours of stopping the RAM 2500 engine.

What does it take to measure the battery in a RAM 2500?

  • RAM 2500 battery terminal voltage when the engine is stopped
  • RAM 2500 battery terminal voltage with the engine running

To test the battery in your RAM 2500 with a multimeter, you need to connect the red probe of the multimeter to the positive (red) battery terminal of your RAM 2500 and the black probe to the negative (black) battery terminal of your RAM 2500.

The RAM 2500 battery terminal voltage should be at least 12.5 to 12.8 volts after 10 to 12 hours of engine shutdown. If the value is less, then the battery in the RAM 2500 will have to be replaced.

RAM 2500 battery terminal voltage with the engine running should show 14.0 – 14.5 volts, a deviation in any direction is undesirable. This measurement is not indicative of the battery but of the alternator in the RAM 2500 and the charging circuit parameters.

How do I charge the RAM 2500 battery?

To charge the RAM 2500 battery, you will need an inverter microprocessor (intelligent) battery charger. They charge the battery by pulses. The battery chargers are small, lightweight, and easy to use when charging the RAM 2500.

When charging your RAM 2500 battery, select the correct charging current to prevent the battery from aging prematurely. The higher the charging rate of your RAM 2500, the higher the current that passes through the battery, which will damage the battery. The current rating is 10% of the battery capacity. If your RAM 2500 uses a 70 Ah battery, then the charging current should not exceed 7A. The lower the charging current, the better the RAM 2500 battery will charge. Do not allow the RAM 2500 battery to be completely discharged, in which case you will not be able to restore it and you will have to buy a new battery.

What tool do I need to replace the battery in my RAM 2500?

You’ll need two wrenches: a 10-mm open-end wrench, and a 13-mm socket wrench.

How do I properly remove the terminals when replacing the battery in the RAM 2500?

First, you need to disconnect the black (negative) battery wire in the RAM 2500 (otherwise you can make a short circuit), then you need to disconnect the red wire from the battery in the RAM 2500.

How do I properly replace the battery in the RAM 2500?

  1. Turn off the RAM 2500 engine ignition
  2. Remove the cable from the negative battery lead in the RAM 2500, and then from the positive
  3. Remove the battery mount and then the RAM 2500 battery itself
  4. Clean the area in the RAM 2500 on which the battery sits
  5. Clean the lugs of the power wires in the RAM 2500
  6. Install the new battery and secure it in the seat in the RAM 2500
  7. Connect the cable to the battery positive terminal and then to the negative terminal

We hope the review helped you make the best choice for yourself and your RAM 2500.
