Buy a battery that fits with the most CCA you can afford especially if you live in a cold climate.
Mercury wants you to install a battery with at least 525 marine cranking amps if you boat in the summer, and 1000 marine cranking amps for winter boaters.
It uses a group 34 battery with a minimum of 500 cold cranking amps.
Take your battery to Napa and have them test the cold cranking amps, they'll tell you whether or not you need a new battery
Group 34, approx 500 to 600 cold cranking amps.
According to the owners manual , the 3.8 liter came with a ( 650 cold cranking amp ) battery - Motorcraft BXT - 65 - 650 and the optional battery was ( 750 cold cranking amps ) - Motorcraft BXT - 65 - 750 ( battery group size 65 )
varies, go out and check on top of battery, should have sticker that says cold cranking amps. all batteries should run 12.6 volts, do the math from that.watts = volts * amps , take the CCA (cold Cranking amps) number on the Battery and multiply it by 12.6No one answer, as there is no one car battery. Most are 12 volt batteries, but that can really be anywhere from about 13.2 to 11 volts. A standard large battery will have ABOUT 50 amps of current. Multiplying volts times amps equals watts. 12 x50= 600 watts. HOWEVER- you cannot draw that much power for more than a few seconds. Heat buildup would damage battery.
Answer 1No difference, but cold cranking amps is what is in battery to start. Answer 2Answer 1 is correct so far as amps are amps. However, the ambient temperature to which the battery is exposed greatly affects the amount of amps and rate at which current can be released. Therefore, most batteries have specifications on a decal for the cranking amps for which they are capable.The first spec ["Cranking Amps"] is at a "normal" temperature of [I think] 70 degrees F. The second spec ["Cold Cranking Amps] is at freezing [32 degrees F, or 0 degrees C].Since the battery output is lower at lower temperatures, the Cold Cranking Amps will be less than the Cranking Amps.j3hAs per the JIS specification for automotive batteries, Cold Cranking Current in Amps is tested at -18deg C and not at 0deg C. depending on the different Ah capacity, each 12V battery will have different CCA amps and durationThe battery will be brought to -18 deg C and then it will be discharged with the specified current, say 350, 400 ,450 A until the voltage on discharge drops down to the specified value. The duration in secs to reach the end voltage is noted and compared with the specified values in the spec.
BCI group size ( 65 ) fordparts.com has batteries listed for each of the available engines at 650 to 850 cold cranking amps
Batteries are not measured in Amps, but rather as Amps they can emit in an hour. The standard home unit for battery power is AH our Ampere Hour.At 12 volts the amps in your battery are then described in Ampere Hours or Amps per hour.From that we get that if the battery was plugged into a 12v device that drew 225 amps, your battery would run out in 1 hour.Similarly if it was connected to a device requiring 112.5 amps it would take 2 hours to run down.Wikipedia has stated that this is an approximation, that at really high currents (measured in how many Amps you are currently using) the battery life is shorter than expected and that the Ampere hour is generally supposed to consider a 20 hour cycle of discharge(therefore meaning lower amps per hour)This brings the battery back to it's "normal" drainage pattern.@ 12v and 11.25A your battery would take 20 hours to drain.
I don't know the physical dimensions but a battery with at least 650 CCA (Cold Cranking Amperage)
BCI group size 66 ( for the V6 and V8 ) 650 CCA or optional CCA 750 ( such as Motorcraft BXT-66-650 or Motorcraft BXT-66-750 ) CCA - cold cranking amps
buy a battery load tester, or simply take your battery to a store that sells them and have them test you ccv's.
