My battery was fine, and then the cold weather came! I took my battery inside and charged it and it will barely turn the motor over.it has 525 cca and i was wondering if getting a battery with more cca will fix the problem?

Re: 1991 Explorer not starting
Boy the cold weather has wreaked havoc on batteries. Get a new battery. 525 cca seems a bit small, I would put in a higher cca battery just for peace of mind. After you install it, make sure the charging system is working properly.Hope this helps.

cold weather kills batteries this time of year...heres why..most batteries are a chemical factory..the acid and water separate as the battery discharges..also the chemical process is lessened when the air temps go below freezing by around 50% or more depending on the age of the battery..in extreme cold areas, external heat sources are required to keep engines warm enough to run..in alaska for example,the batteries are taken out entirely and put inside to keep warm..sometimes a fire pit is used to warm the engine from below (red hot coals no flame)..also in very cold weather, the engine oil will get very thick..in some cases the oil will actually glue the engine semi solid..locking it up..if its a cheaper oil that whathappens..I like 20 miles north of st louis in illinois and when it gets below 30 degrees outside i place a under cabinet 350 watt heater(used for keeping food warm to serve) upside down under my engine overnite..this keeps the block warm and the oil thinned out..and works very well for me..my car will start whe no one elses will in my neighborhood..hope tyhis helps you..
It is normal for batteries to lose a good deal of their power due to cold temperatures. If you want better starting power, try using a battery charger/maintainer overnight. It should charge at no more than 2 amps. The slow trickle charging overnight will charge and warm up the battery and allow it to develop full power for a cold morning start.
This really sounds like a problem with your battery. I know you said you checked it, but is it really putting out the appropriate voltage (12.66 volts) and CCAs? Even draining the battery once can damage it (especially in cold weather), and cold weather reduces the CCAs a battery can put out. A weak battery can cause those codes. When the vehicle hesitates to start, does that typically happen on colder mornings or after the car sat for longer periods of time? I would double-check your battery. If it's the original, it's near its end of life anyway.
You can try insulating your battery (cold might still get thru) or purchasing a solar recharge kit from an aftermarket company. Cold weather will affect the chemical reaction between the plates of the battery and will not put out the high amperage required. I would also recommend to keep a portable battery booster in case you cant get a solar charger. Keep the booster in a warm bag inside your trunk and always charged for when this happens. Keep it during the duration of your winter weather. In summer you will be fine.
Get your battery voltage checked.The cold weather will reduce the strength of your battery. The starter solenoid is trying to engage the starter but it doesn't have enough power from the battery to make it happen.If the battery voltage is low then get it recharged .The voltage of fully charged battery will show near to 12 volts.--------------That's it.
You were told the battery and alternator was good? how did they check your alternator? did they perform a load check on the battery? you should check the battery out yourself with a cheap digital meter...it should read at least 12.5v..if not the alternator is not charging your cars battery that is why a jump keeps it going for about a day and then your battery will drain and it wont start again until you get another jump; or your serpentine belt is worn out and slipping. Do the windows fog up in cold weather only?...because that would be normal with you sitting in your car for awhile with a dirty inside windshield and trying to start the car for long time..it just could be a coincidence. The only reason your car started that time in haste was because it sat overnight and it gave the battery a chance to charge up somewhat and it barely had enough juice to turn it over. have AAA or someone jump start you, then take a voltage reading right as it starts and you should see the voltage rise to about 14.5v then stabilize slowly down to 13v or>. this voltage is being properly regulated!
Check all wires and switch used to wire the push button ignition. Make sure none have melted due to the stress from hard starting in cold weather. If a thick enough guage of wire was not used it will get hot and could melt.
Most vehicles have problems starting when it is cold. Short of installing a block heater, your problem lies in your battery. if it is cold in your area for a few months of the year, my suggestion is to invest in a higher rated CCA battery, and a block heater.
Cold Cranking Amps is a rating used in the battery industry to define a battery's ability to start an engine in cold temperatures. The rating is the number of amps a new, fully charged battery can deliver at 0° Farenheit for 30 seconds, while maintaining a voltage of at least 7.2 volts, for a 12 volt battery. The higher the CCA rating, the greater the starting power of the battery.
This morning it was -19F here, and my new car gave me a fit starting, so you are not alone. Replace the battery, and pay a little higher premium for CCAs and you should be fine.
