I own an Innova 3300 that over estimates voltages, 9V PS reads 10.5, 12V reads 13.8, 3.7V battery reads 6.24 what can I be doing bad??

On a 12v car battery. While the vehicle is running, it should be 13.5-14.4V and while off, should be 12-12.5V

It may not be reading wrong. Batteries usually put out a little more than they are rated.I know my car battery usually puts out about 13.5V

what are you measuring? Are you measuring batteries? If so, then it's pretty normal to have a higher reading except the 3.7V one.

While as some people suggested, a 9V battery may read slightly higher, a 12V automotive may read closer to 14V than 12V, but a 3.7V battery should never read higher than 4.2V. Odds are your meter left the factory miscalibrated or not calibrated at all and some part in it is out of specification. If you are adept at tracing electronic circuits then you may be able to open the meter and determine the correct component to change to fix the miscalibration issue, but it would be more of an academic exercise than a good investment of time since you will still end up with a low end meter selling for $8.

I had similar problems, and purchased a higher quality model. I hope I am not giving you bad advice, but that is what I would suggest. It probably is not you, but the Innova model.

Just remember not to exceed the 10a limit, I really don't recommend running it at 10a if you dont have to, and if you do, try to get more cooling. Make sure the plus and minus are the correct polarity, and (not neccessary, but recomended) put a little voltage moniter on the output, to make sure that it is not going above 19.5v

200 V peak is clamping voltage -- i found this out by checking out a different site's tech details on this same unit.

you got too much voltage flowing.batterry need somewhere around 14 to 16 volts.

I have the 4000 mAh version which is not pictured on the page I'm looking at right now. But according to the back of it, it's Output is 5V ~ 0.5A.

I ordered both, they screwed up and sent 2 of the 1.2 volt. Sorry, can't help.

I have been asked this before. There is no information on the package regarding voltage.

I have not idea? The power supply is pretty nice and I am very happy with it but I am only using it on at P7-300.

When I first saw this product had a cut out voltage of 14.2 i thought 'hey that's low...' in my humble opinion(the only meaning of IMHO i know) you should look into the difference between charge types, float, bulk... then you will understand the numbers on this unit, and your batteries a bit better.

I was pretty sure it took a 9v, I just opened mine to confirm. 9 volt. Take care...

The small details on the back simply show AP-10-12V. Not sure what that means but I'd be on the safe side and use a power adapter. Don't wanna burn out this baby

I tested the voltage when batteries were very low and fully charged. My controller did what the specs said. Good luck

The clamping voltage is 400v on L-N and 500v on L-G and N-G. The clamping voltage is NOT 330v (best) as incorrectly listed in one popular review and on APC web site. On close examination on their box, there is zero information given other then the Joules rating (which is the first clue something is afoot). If you open the box and check the back it lists the clamping voltage as listed above, not the 330 volt clamping voltage commonly misreported. PS clamping voltage and let through voltage are not the same thing. Clamping voltage is the max voltage let through (ie 330v with 330v clamping or 500v is it has 500v clamping (very poor)) let through voltage is the difference between the maximum allowable normal voltage (~170v) and the clamping voltage ie 330 on a good protector which would give you a let through voltage of 330-170= 160v over max normal voltage. In conclusion APC website and popular review are not correct / and or misleafing. The surge protector offers poor surge protection. Loot for a better one with a 330 clamping across all three lines, has a high joules rating for longevity 2000+. There are other important factors, but those are the biggest two, and I don't have the space to discuss further. Educate yourself and be warry of devices and companies that don't put their specs on the box as is the case with this unit/company.

Mr.McDaniel my INNOVA model is 3150 and not 3130, but I can tell you this, I like my Code Scanner. Good luck.

Touch pads and touch screens are sensitive to over-voltage. Check the voltage with a volt meter. ~10% over or more has been known to cause jumpy, unresponsive or 'mind of it's own' - type problems. My PA-10 is rated at 19.5v but puts out 20.0. No issues so far.

I assume that you replaced both batteries and your unit is a APC BACK-UPS XS 1300VA, with AMD board, 1 AMD 4-core cpu, on-board graphics and Samsung 27" (?) monitor, I am drawing 90 watts total and the UPS says I have 52 minutes estimated run-time after 3 months of service. Same as new. You may have a bad battery but do as the first person suggested, try a reset. In a UPS you always replace all the batteries when it is time - hope this helps

SORRY.......it requires 2 9V. Everyone helped you with that one, and I made the mistake.
