Question 1

does this work on a 12 V  8D diesel truck battery?

Accepted Answer

This will work on all batteries 12 volts and less   A carbon pile tester would be a better choice for the larger 8D battery

Question 2

As this tester puts a 130 Amp load on the battery being tested, is that too much load for testing small batteries such as motorcycle & lawn tractors?

Accepted Answer

Hi R.W.,  this tester will certainly tell you if smaller batteries are in good shape but it is kind of over kill as it works by resistance testing.  Kind of like plugging a toaster onto your battery.  It will draw a lot of juice off the battery in just one test with smaller batteries so if they are weak you will know it fast and they will likely need a recharge afterward.   I use it for 4 and 8 D size batteries for starting large diesel engines.  I would suggest a lighter amp load tester for what you are doing.  Something around a 50 amp range.Hope this helps.Paulpaulmgriswold@aol.com

Question 3

So this would tell you if a car battery is working properly Etc?

Accepted Answer

It puts a load,like you're trying to start your car,on the battery, and will tell you if the battery is bad. Most batteries last  5 to 6 years cheaper ones less so if it's old just buy a new one
 But if it's newer you might want to check it before buying a new one. The battery has to be charged though, you cannot check a dead battery , so unless you have access to a battery charger this won't help you.

Question 4

will this work on 8 volt golf cart batteries?

Accepted Answer

Hi Cabo,  It might as it has scales for 6 or 12 volt.  It would read a little high on the 6 volt scale when checking 8 volt.  I can't promise it will work though.
