I am trying to find a fan for my Sears 300 amp battery charger

All batteries need to be fully charged. It should hold about 12.3 volts. Amps is the important thing and if you have a ful battery, and the machine turns sluggishly, it means the battery is low in amps. This reduces over time and can only be tested with a special tester. Any Interstate shop or garage will test it for you free of charge.

I got this free Pdf manual from reliable-store. com for free and I don't think Ive visited a mechanic or fixya for help for more than 3-4 times out of the 20 times I fixed the chipper in these 4 years

Try charging the battery with a small 10 amp battery charger with the negetive terminal removed, remove the charger and let set overnight. Hook the battery back up the next day and see if the car will start. If so, the alternator is bad. Drive to your nearest parts store and they can check the alternator to be sure it is bad. or just skip my first step and just go to the parts store, they will check the battery and alternator for free.

Maybe your battery was overfilled. You should be fine. Well, you may have to charge it again, lol. If you don't have a voltmeter to test it, just try starting. If it starts, the alternator should take care of charging it up after about 30 minutes of running. 10 amps in one hour is not too much. I thought all battery chargers sold today had an automatic function to reduce output down to a trickle charge (about 2 amps) after sensing battery was nearing full charge. My Sears charger is like that. Sure helps when you forget and leave it on all night! I've done that more than once and no ill effects.

3 possibilities are:

• Dead cell in battery; a battery with a dead cell won't accept a charge from the alternator
• Bad alternator; if the car will run on it's own without stalling, the alternator is probably still good; if the car stalls you may have alternator problems
• Bad starter; (assuming you've ruled out alternator problems) a bad starter will start when the car is cold; once warm, it requires more power to engage than the battery has therefore, it needs a jump start

I'd advise bringing the car to a shop (most autoparts chains will do a free electrical system check) and have the electrical system checked.

Couple questions: Is the battery three or more years or older? If not a maintenance free battery, is it full of water (if you can easily remove the caps, it is NOT maintenance free). How dead it is? Have you taken any measurements? Voltage should be 12 volts and acid should read 1200 on a fully charged battery. The charger you are using, what is its capacity? Most vehicle batteries can produce 300 amps or more when charged. If you have a 10 amp charger it would take 30 hours at 10 amps to fully charge a 300 amp battery. The battery on my vehicle is rated at 1000 amps just for a point of reference.

At 20 minutes I wouldn't expect to see much change in the condition of a dead battery with a consumer grade charger. If the battery is out of the vehicle, I suggest you take it to your local auto parts store to have it tested. If it needs charged, they may be able to put some juice in it for you for a couple bucks. If it needs replacement, you have 1/2 the job done and you will not have to worry about the core charge since you have the old battery with you. While you are there, the guy or girl at the counter can probably tell you what the age of the battery is.

If you are keeping this car, I recommend you get a premium battery for your car. The best only costs a couple bucks more.

I hope this answers your battery question.

Thank you for you interest in FixYa.com

How many amps does this charger put out????
A small trickle charger will take forever to fully recharge a dead battery, you'll need to have a battery charger that can put out enough amps to properly charge a dead battery.To clarify, the chargers sold at Sears, the large square types on wheels are the best for charging dead batteries and they also have an amp meter telling you how much the battery is accepting. After you charge your battery, you should be around 12.5 volts to 12.7 volts. DO NOT OVER CHARGE!!!

For a general battery seletion guide, I checked Sears.com and came up with this page:

http://www.sears.com/shc/s/s_10153_12605_Automotive_Batteries+%26+Chargers_Automotive+Batteries


It showed 6 results for a FWD '04 Chrysler Pacifica - but there's also an AWD option for that vehicle and I'm not sure what type you have.
If that link does not work you can locate the battery selection guide by going to:
Sears.com
and from the left menu selecting in the following order...
Automotive > Batteries & Chargers > Automotive Batteries

They probably had a series of batteries that were bad, and unfortunately, you got 2 of them. Take a credit (as it must still be under warranty) and get another one, or buy another brand. I don't think it has anything to do with your car.
