Whats the problem?<p>Is it dying?<p>How many times has it died completely and needed a jump start / recharge?<p>Typically our batteries are maintenance free. <p>

Re: (chinaonnitrous1)

No directly attributable issues. I guess I can base it on fluid level. My understanding though is a weak/old battery can cause random otherwise undiagnosable issues. <p>It has not died at all. I'm just generally refreshing my car, so covering all my bases.<br>

Re: (chinaonnitrous1)

You never just add water. The way a battery works is electro-chemical. Your plates are being eroded through the process which eventually causes the battery to fail. If you just add water you are just weakening the dielectric. I would just change the battery, since I don't like things to fail when it is the least convenient time. But at a minimum you need to replace the dielectric, both acid and water need to be at the right proportion. Don't just pour it in, you need to test what is in the battery. They sell a hand-dandy tester at the part store. You lose Hydrogen through the charging process and most of that is from the water. This is why people say just add water, but if your dielectric constant is wrong the battery will not operate efficiently. I don't like to mess with the stuff. My father is the cheap guy who buys used batteries and always has problems. Having the car start every day is worth the money. <p>Edit: You don't need to mess with it if everything is working. I change mine at the first sign of trouble.

Thanks for the info dave_n_ruth... Believe it or not I got the add water idea from the owners manual! Check it out:<p> <A HREF="http://apps.volvocars.us/ownersdocs/2004/2004_V70/04v70_08b.htm#pg140" TARGET="_blank">http://apps.volvocars.us/owner...pg140</A>

Re: battery - replace or refresh? (iamnotmad)

As long the battery isn't drinking/evaporating the water the amount like we drink spirited-fluids ... it's healty.<br>My 05/2003 one hasn't needed a drip of water sofar. My dad's one only needed topping of 5yrs ago and it was 2months ago still at full.<p>Batteries nearing their end of life will evaporate more water then healthy ones because they need a higher charge to reload (so they get warmer/hotter). Be sure to blow out the little evap-hose connected to the battery from time to time so this explosive/smelly gas can escape safe.<br>The water is evaporating naturally, you will NOT weak the concentration acid/water if you add water to max. It was TOO acid before you added water <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/rolleyes.gif" BORDER="0"> <p><TABLE WIDTH="90%" CELLSPACING=0 CELLPADDING=0 ALIGN=CENTER><TR><TD><i>Quote, originally posted by <b>dave_n_ruth</b> »</i></TD></TR><TR><TD CLASS="quote">Edit: You don't need to mess with it if everything is working.

You also only change the oil every 7,500 miles right? <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/tongue.gif" BORDER="0">

Anyway, sounds like since I have no real direct issues with the battery, I'll check the water level, if low add some <B>distilled</B> water and charge it up. Otherwise if water levels are good, I'll leave it.<p>I wonder if the small dehumidifier I have in my garage sucks extra moisture from the battery?

Simple answer - you have a 2004...change your battery and have no worries till 2013. There are other things with the car requiring more of your attention.<p>Problem solved.

Re: (JARMO)

Agree, it usually happens in the winter time. I have yet to change my battery, but the second it fails I will get a new one. Too much other stuff to spend time on with the car. To little precious time to be spent on it as well. <IMG NAME="icon" SRC="http://********************/smile/emthup.gif" BORDER="0">
