Is it bad to take battery test in winter?

If the test really showed a bad cell (could be true – batteries do sometimes fail young), then I think continuing to drive on it is a bad idea, especially with winter weather coming. You risk getting stuck somewhere cold and inconvenient. I think you can get a free test at the big chain parts houses or maybe at Sears.

How can you tell the date of manufacture of a battery?

That’s why when a battery is purchased you should look at the date code on the battery to determine it’s date of manufacture. If you don’t know how to read the date code on a battery, then ask for a battery from the back of the battery storage rack as these are the newer batteries, and the batteries at the front of the rack are the older batteries.

Can a battery tester detect a bad cell?

This type of battery tester is capable of testing a discharged battery without recharging the battery. And it’s capable of detecting a bad cell within the battery. If the conductance battery tester indicated a bad cell, I’d believe it.

How can I tell if my car battery is good or bad?

A voltage drop test can tell you if your battery cable is the problem. Using the Voltage setting on the multimeter, first touch the probes to the battery terminals to determine the voltage of the battery. A fully charged battery should have about 12 volts ready to go.

When to know it’s time for a new car battery?

Car batteries are no different — as batteries age, they lose their ability to hold a charge as long. If you have an older battery that doesn’t seem to hold its charge as well, it’s probably time for a new one. But what about if your battery is new and requires jump starts?

When was the last car battery test done?

There was really nothing consistent as to one brand always being the best. Based on my back copies, it appears that the last battery test that CR published was in November, 2013, so these results may no longer be valid. Anyway…here are the top three in each group size: Thanx for the update.

How to know the reading battery test results?

Reading Battery Test Results. The only way to determine this is by load testing the battery and applying a load equal to 3 X the starter current draw. After 15 seconds it should be a minimum of 10.2 volts. This also means the battery should be on a charger for at least .5 an hour before a test and preferably an hour.

Can a load test tell if a battery is about to fail?

There is no RELIABLE test that will tell you when a battery is about to fail. A load test will only tell you that your battery has already failed and that it’s only a matter of time before you experience starting problems. If your battery is 5 years old, replace it.
