Problem Description:

My company recently purchased the BT100 battery tester for the field technician. However, due to the vague instrution, we were wondering the correct setting and testing methods for AGM Sealed batteries. Our equipment used anywhere from 35 to 100+ AmpHour batteries, and we are not really sure on the correct testing method. Batteries not rated in CCA or CA.


Solutions for engineer:

1 It is same methods as when you testing CCA, just when you choose battery ,you select AGM.

2 If do not know Rated CCA, better directly ask the battery manufacture. If really can not get the rate, can use BT100 battery tester to test a new battery to get a CCA data, but this data can only be used for referrence.

How TO Test Your Automotive Battery

It’s important to test your battery and electrical system regularly, not just when it’s starting to show signs of weakness.  Proactively testing it (or making sure your mechanic does) at least once a year will hel reduce your chances of failure.  Refer to your owner’s manual and your battery tester manual for instructions. Review all safety instructions that came with your tester and battery.

Note: Conventional wet cell car batteries are filled with a mixture of water and sulfuric acid. Wear gloves and handle the battery with care so no liquid spills on your skin or clothing. Battery acid can cause severe burns. If a spill does occur, wash with plenty of water and neutralize the acid by applying baking soda.


Fully charged automotive batteries should measure at 12.6 volts or above. When the engine is running, this measurement should be 13.7 to 14.7 volts. If you don’t have a multimeter to tell you the voltage of your battery, you can do a test of your electrical system by starting the car and turning on the headlights. If they are dim, that indicates the lights are running off the battery and that little or no charge is being produced by the alternator. If the lights get brighter as you rev the engine, it means the alternator is producing some current, but may not be producing enough at idle to keep the battery properly charged. If the lights have normal brightness and don’t change intensity as the engine is revved, your charging system is probably functioning normally. If you’ve been experiencing problems with your battery system and the headlight test checks out okay, you should check whether or not the battery is holding a charge, or if something on the vehicle is discharging it.

There are three likely scenarios that could explain the problems you’re having:

    1. A high parasitic draw (“key-off” load). This can quickly discharge a battery and decrease its service life. This may be caused by a trunk light, cigarette lighter, clock/radio, alarm system or any other electrical device. Current drain on the battery can be checked with an ammeter. With the ignition off, disconnect one of the battery cables. Connect one ammeter lead to the battery and the other to the cable. The normal current drain on most vehicles should be about 25 milliamps or less. If the key-off drain exceeds 100 milliamps, there’s an electrical problem that requires further diagnosis. If you don’t want to take your car to a mechanic, the easiest way to isolate the problem is to pull one fuse at a time from the fuse panel until the ammeter reading drops.
    2. A problem with your battery is causing it to not hold a charge. To check this, wait 12 to 24 hours after charging to the full voltage, keep the battery out of the vehicle and measure its voltage. Another faster but less preferable way to do this is to turn on the high-beam headlights for 15 seconds, turn them off, wait five to 10 minutes, then check the voltage. If you measure the voltage of the battery the next day, week or even a month later, the voltage should be close to the max voltages listed above. If the voltage holds when not installed in your vehicle, but drops when it is in your vehicle, see 1 above.
    3. The battery was somehow discharged, and your maintenance charger can’t properly charge your deeply discharged battery. Please see the directions for charging a deeply discharged battery.

Add:you should know about  battery ratings before you  test or replace  car battery:

Cold Cranking Amps (CCA) This is the most common battery capacity rating. The rating is the number of amps the battery can deliver for 30 seconds at 0 degrees F. while maintaining post voltage of 7.2 Volts. For reliable cold weather starting, most vehicles require 400 to 600 cold cranking amps. Larger displacement engines require more cranking amps. Some batteries are rated up to 1000 CCA, but may sacrifice reserve capacity to achieve high short term outputs.


Cranking Amps (CA) This is a less meaningful rating. It is the same as CCA except it is measured at 32 degrees F. A battery’s CA rating can be converted to CCA by dividing the number by 1.28 (Example: a CA rating of 500 amps becomes 390 CCA).

Reserve Capacity (RC) Think of this as the battery’s staying power. This is the number of minutes the battery will deliver 25 amps and still maintain a post voltage of 10.5 Volts. The higher the reserve capacity rating, the longer the battery will last if the charging system fails.

 Amp Hour Rating (A/H) This rating is not used much any more. It measures low current draw for 20 hours while maintaining a minimum post voltage of 10.5 Volts at 70 degrees F. (Example: a drain of 3 amps for 20 hours = 60 A/H rating).

Battery Installation

When installing a new battery, clean the posts and inspect the battery cables. Also, check the negative battery cable ground connection and the integrity of any engine ground straps. Loose or corroded connections can cause starting and charging problems.
