## Questions & Answers

**Q: Can I use this to test lawn mower battery. Also does it show any status of alternater?**
A: If the lawn mower battery is a 12v battery it will test it.  As for testing the alternator - I don't think so.

**Q: Can this be used to test 2 6V batteries connected in series to make one 12V source?**
A: Documentation states to not use with connected (in series) batteries.

**Q: can it test 12 volt emergency exit light batteries?**
A: Yes it will show either CCA or AH (cold cranking amps or amp hours).  You need to know the battery's specifications to know if the battery is good or not.  It has saved my battery more than once by knowing when to recharge (off line battery).  Very good at a great prijce.

**Q: Can this test 6 volt and 8 volt  batteries**
A: No, only 12V.

## Customer Reviews

### ⭐⭐⭐⭐⭐ Accurate and easy to use. Quality at low cost equals great value
*by S***E on May 26, 2018*

This is an easy to use accurate battery tester. I tested 3 car batteries new to 5 years old and it showed they were all good and also showed percentage of capacity left proportional to age difference and use. I tested 6 12 volt sealed L/A batteries from uninterruptible power supplies and it correctly failed them. It correctly failed a battery from my garage door opener that showed proper voltage but would not operate the door. It passed the new replacement. It showed a good battery was replaced at a friends house for her alarm system that I had replaced 2 years prior. She had an error on her system and replaced the battery thinking that would fix it. I normally use a carbon pile load tester for auto battery tests, but this little tester is now my first choice. Small and light, it is easy to carry around when I need to go mobile for testing batteries.

### ⭐⭐⭐⭐⭐ Easy to follow instructions
*by P***A on July 14, 2018*

Easy to follow instructions. Heavy duty cables and strong springs in the clamps. Case seems to handle most impacts. Used three times and shows no sign of failure.

### ⭐⭐⭐⭐ it works.
*by E***E on June 8, 2019*

inability to store readings after disconnecting from batteries.
