## Questions & Answers

**Q: does this work on a 12 V  8D diesel truck battery?**
A: This will work on all batteries 12 volts and less   A carbon pile tester would be a better choice for the larger 8D battery

**Q: 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?**
A: 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

**Q: So this would tell you if a car battery is working properly Etc?**
A: 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.

**Q: will this work on 8 volt golf cart batteries?**
A: 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.
