[Princess Auto] 100A Battery Load Tester $13.65 **HOT**

I was at SE Calgary Princess Auto and noticed this deal.
Website shows regular price, but in-store sticker says otherwise (see attached picture)

I bought this one at $19.99 about 6-7 years ago and it's been working well to test health of the battery and associated parts. Not super high tech, but it gives you some idea where to start looking if you are having electrical issues. Plus it's analog so don't have to worry about digital screen not working in sub-zero weather.

Some YT videos on how to use the tester.

Not a bad price, but 75% of drivers have no clue how to change dead battery, so this tester will offer no help. If it's dead, the car won't start, they call CAA, pay $$$$ and it's done. Up voted - just for PA's awesome return policy Grinning Face With Smiling Eyes.

I have this too and bought at $19.99. This is an excellent price. Works well to test my battery health.

Agreed. Probably something to have to use once a year, like myself, to test the battery.
CT has similar unit for much more inflated price at $51.99.

Man I need this. Between a cottage rental and trailer I've got a lot of batteries to maintain (7 golf cart, 4 marine, 2 small engine), not to mention the cars.
Might bite bullet and just pay full price.

You can but require a significant setup. This is way better at that price.

A multimeter, assuming it is set to measure voltage, will measure a floating voltage. It does not load a battery down with actual current draw, which simulates a battery in use (staring, accessories, etc) of a vehicle electrical system. A load test is the only true battery test. Arguably a conductance tester gives a bit of an insight into cell condition and is able to estimate battery health and state, but an actual load test is still best.

One thing to keep in mind, this load bank is only capable of drawing 100A. A proper load test of large batteries should be at half their rated CCA (cold crank current) specification, and as many car batteries are 700-800CCA, a load tester should be able to draw more current.

Princess Auto also sells a 500A carbon pile tester, with variable current draw (up to 500A) and dual meters to see actual current draw AND voltage drop at the same time. Great tool:

And on sale as well.

You're correct, set your multimeter to DC 20v and your all set for testing 12v batteries.

That's incorrect! No-load testing will give you a general indication of the battery's condition IF you don't actually use the battery the way the battery was intended to be used. See posting just above yours.

In case a Youtube video is better, here's a great video that explains the difference between using a multimeter, a load tester and one of those electronic conductance testers -

Exactly. This thing isn't capable of performing a proper load test on car batteries.

No you can't THIS IS A LOAD TESTER albeit a SMALL load tester

For anybody wondering...you can load test your car battery with a multimeter.

Pull fuel injector fuses or disconnect power to them. Crank engine while measuring voltage. A good battery will will hold at least 9.5 volts for 30 seconds of cranking.

I'd buy this one at this price in an instant, another valuable tool to have around in the garage.

I test my two car batteries once a year heading into colder weather, also use when the need arises for family & friends. I have the Schumacher load tester, however this Princess Auto should be comparable.

I first changed a car battery at the ripe age of 41, without the help of YouTube... Loosen the 2 screws holding the bracket holding the battery, take old battery out, put new battery in, done deal. The shop wanted $40 for this 5 minute operation...
But yeah, you're right, most people don't bother, because idiocracy.

Correct me if I’m wrong, do car shops test your battery with the fancy tester for free generally?

Bought Ancel BST100 (link) for C$27 in early February. Arrived in 10 days from China. I noticed if shipper is Alixepress Standard Shipping, goods tend to arrive sooner.

This model has 3 functions. Battery test, Charging test and Cranking test. I have only done battery test. From what I read, the other 2 tests requires 2 people.

I find the price quite reasonable.

I see it is available online, although the price tag is $39.99?
