Are these supposed to be accurate? I tried two of them, batteries charged to 12.65V are barely on the 12V line.

Who knows how accurate these cheap gauges are... Checked mine with my analog meter: slightly more than 12 volts at the battery - perhaps 12.1 or 12.2. 12 volts at the terminals on the back of the gauge while the gauge read a hair more than 12. Yours might be different of course.

I have not gotten to that point yet, however I'm just about ready to do so!

I have one sitting right in front of me now on a panel. I have a SunForce controller that is showing 12.7 volts when I switch over to monitor voltage and right below that is the Sunpro CP8215. The reason I have both is that I usually leave my controller switched to current as I don't want to wear out the switch going back and forth. The Sunpro is reading the same...as far as you can accurately interpolate. What I have discovered is that depending on where you put a volt meter, the voltage measured will vary a little. I also bought 2 digital cigarette lighter type gauges at the same time and they both varied by a volt or so. That was when I discovered about the difference where you took the measurement. Overall, I really like the Sunpro. Since it uses old technology lighting, I just disabled it as I don't want the useless battery drain. Having left it connected 24/7 over a year now it is still performing just fine. Hope this helps. BTY.. I would buy another. The black is fairly nice looking.

Not quite. The claim is that they will improve after the first few charges. I get anywhere between 8.5 to 8.7 volts on full charge. So far they seem to last just as long as any other brand in my motion detectors.

Sorry to question your capabilities ... have you ensured that the batteries are all in the slots, in the right direction? My original batteries were dead, as sent by the manufacturer. But the new ones tested fully charged, and I was careful to place them in the slots as indicated by the arrows.Give that a shot and see.

Read the reviews and they should help you. They are supposed to be better than regular batteries.

I own UltraFire and Tenergy Brand of 18650@3000ma. I have 5 set of them. I only had 1 bad one that won't hold a charge in storage. The rest seem fine I measure the voltage on them to check. After a fresh charge it measure 4-4.3 volts. Then it drop to 3.8,4.1 for over about 2 month. I think like everything a little luck is involve. I read the other peoples reviews and 4-2 stars to me if the price is right I'll take a chance. So far it a good deal Beside they are all made in CHINA no matter which brand. The Trustfire charger works fine too. Voltage on batteries checked before this reply...

Mine seem to work fine, stuff coming from China you never know. I bought some portable phone batteries and they lasted 2 weeks then all dead !!! Mine are good though, good luck.

How would I go about conducting such a test? I don't think it would be worth the time and/or effort to do it.I also have a pair of these batteries by Philips, and a pair of Rayovacs, and two devices that use them, and I don't find any noticeable difference in performance.

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.

I would check with the manufacturer because all 12V batteries aren't created equal; technology could be different (liquid acid vs gel etc).

I have the same issues! I have had great success with the 750ma (green) batteries, so I ordered some of these 900ma (blue) batteries hoping for longer life. Instead I got varying voltages, higher than 3.0V that the flashlight did not like, plus, they are slightly bulkier and get stuck in the flashlight. They should be built to the same standard, but they are Not!

These are HHR 75AAAB. I assume they are the same voltage, but hold a different amount of energy. If you use them, make sure all the batteries in a stack are the same kind.

Well, Chad. The ones i bought work Perfect, No Issues. Sounds like your problem could be a Ground Issue? I guess i would hook them up, one at a time, to a good 12volt battery. makeing sure if the problem follows the same light. then...take that light apart and look for any possible Faults?

Jeff, I have used them without problem for months now. It may just be that you got a bum set. I have been running only Oly BLN-1s in my OM-Ds and E-M1 for the last two months, so decided to see how my Wasabi batteries were doing in my bag having not been on a charger in more than two months just for this response. I can say that BOTH my Wasabis were still fully charged (based on my E-M1's battery display) and are working fine. I'd suggest contacting them to see if they can help you out. Jamie.

How did you try to measure 24 volts? If you used 2 twelve volt batteries in series make sure they were connected one + lead to the other - lead. Or try to measure 3 nine volt batteries snapped together. You should get 27 volts. I think there is a calibration pot on the back of the meter. It is very small and you will need a jewelers screwdriver to adjust it. Make sure the red lead goes to the + termingal of the battery. Try again and let me know. You could have a bad batch of meters. Mine worked very will on my power supply that goes up to 27 volts. One last thing...are the 24 volt batteries you are measuring good batteries? The meter might be telling you that they are not. Hope this was useful. Also be aware that all meters have a percentage of error. Some are + - .1% + - .01%. No matter how expensive the meter it will have error tho very small. The smaller the error, the larger the price. These cheap but beautiful meters are good enough for battery monitoring. I wouldnt use them to build a computer power supply.

I would say it is fairly accurate. However, I don't really let my motorcycle battery get that low to really determine how accurate.

Some of my batteries work better than others, but they all suddenly quit giving a very dimm light. These batteries have a voltage regulator that cuts bellow certain voltage (3.2 v). Their regular voltage is not 3 volts but more than 3.6 up to 4.1 v. What kind of voltage regulator they have? Just to cut below certain voltage. I don't think these are good batteries for electronic devices. At least those that require 3 volts. Bad bad.

Silly to check but make sure the batteries are inserted properly (corosponding +,-) second the cathode and anode may not produce enough compression and may need to be bent towards center 1-2 mm.
