The reasons for any Honda Odyssey having a battery draining problem are several. The problems with their solutions are briefly explained below.

Corrosion of Cables

There are several cables connected to your Honda Odyssey battery. The cable can be corroded and drains the battery. This corroded cable also hampers the battery from getting recharged.

Solution

Taking your car to an authentic mechanic and paying him to replace the corroded cables is the best solution in this case. 

Parasitic draining

Several components in your vehicle require electricity, such as lights, AC, stereos, etc. Leaving these components turning on or because of a broken relay will drain the battery of your Honda Odyssey even though you are not using it.

Solution

Follow these steps to save your battery from getting drained:

Step 1: Take off the hood of your vehicle

Step 2: Find the battery and check the positive and negative sides

Step 3: Be careful and loosen the wire connected to the negative side. Carefully pull them off

Step 4: Keep it this way until you start your vehicle again

Step 5: You can jump-start your vehicle after reattaching the wire to the battery’s negative side

This method is a simple way to keep your battery from getting drained. 

Step 6: If this does not work, you can take your Honda Odyssey to a certified mechanic. But before you go to the expert, you need to notice something. 

If all of the electrical parts turn off after you switch off the vehicle, go to a mechanic because parasitic draining may not be the issue here.

Bad alternator

It causes the battery to get drained and consequently lose its remaining charge.

Solution

In the case of a bad alternator, the solution is to replace the component itself. If you do not solve this issue, you can’t drive your car. For a Honda Odyssey alternator to be replaced, you will have to pay $676-$943, including labor costs. However, the alternator itself can be $514-$739.

Dead battery

Usually, after long use of batteries, they die down. If your Honda Odyssey battery has been running for a long time, it may have reached its end. It is also possible that it has started malfunctioning because of dead cells.

Whatever the reason might be, if your battery is dead, you will need to replace the battery.

Solution

Just replace it with a certified mechanic. However, the repair cost will vary depending on the cost of the parts and the labor fees. 

As mentioned earlier, you may have to pay around $750 to replace the alternator. Replacing just an electric relay will cost below $100.

But it is different for the battery replacement. You may have to spend only around $250 or less.
