Lately my car has been giving me warnings about the low battery. Usually when I don't drive the car for a day and the following day I will start the car with a message on the iDrive "Increased Battery Discharge". The clock will also reset every time this happens. Car gets driven about 20-30 km a day (depends) usually 6 out of the 7 days. Should I replace the battery with a new one or buy a Battery Tender Plus and charge up the battery?

Any ideas?

You didn't provide any info on how old the battery is.

Likely the tender will buy you some time but in the end you will still replace the battery. The miles driven seems like it should be OK but there may be a real discharge on the battery when the car is supposed to be off.

It depends on temperature, usage, charge / drain cycle. I have an 8-year old garage queen with 16,000 miles and the original battery load tests OK. It is trickle charged weekly. I would charge your battery with an intelligent charger. Then take the vehicle to an automotive part store where they do battery load testing for free. You will need to remove the trunk liner to provide physical access to the battery posts directly on the battery.

If you don't know or if the battery is over 4 years old then I recommend you replace it.

IMO, the daily mileage you are driving should be enough to keep the car charged. If your battery is old it is due for replacement but if it is relatively new then you could have 'going to sleep' issues. A charger may help but your driving pattern is accomplishing the same result. I see a new battery in your future.

Sorry. It's a 2007 about 5 years old.

I'll give that a try. I have 9 year old Honda still running on its first original battery which I have never recharged.

It's about 5 years old, new battery is the only way to go I guess.

This should only be about a $200 problem if you do it yourself or via an independent mechanic. Don't fall for the dealer $600-$900 service for this.

I just had my battery replaced yesterday with a auto repair shop that?s very trustworthy and reasonable in pricing they installed my battery for about $190 my first battery made it a little over six years. I went to start it on morning and it gave me a quick crazy light show on the displays then nothing so it was time to replace.

Another similar post was just made earlier regarding battery. Get one from your local AutoZone or PepBoys Etc.. and save a ton of money.

Did they register your battery with your car? If not, the cars old charging pattern may ruin your new battery quickly.
