I see 2 digital battery voltage checkers in the picture, do you get 2? If not, which one you get, the one on the left of right?

You get both. The one on the left has the low voltage alarm beeper, it's been working great for me. The one on the right just displays the voltage without an alarm. Originally I thought I wouldn't use that one but actually it's very handy to have. This was a good purchase for me, no complaints.

My former response was incorrect. I am waiting for another order of these, from a different vender. I should of looked closer to the order. I did receive this. It was the shorter one and has served me very well.

2...th one on the left is he voltage checker/alarm. This device you plug into the balance lead of your lipo...and set the low voltage alarm. The one on the right is just voltage checker. This is a useful tool to have in your pocket when you're out at the field. It allows you to easily check the voltage of you batteries quickly.

You get 2 batteries but expect them not to work or least maybe 1, that's what I got, goodluck

If you have a DVM or voltmeter you can run a continuity check on the driver, if it's an open circuit then the response from Christopher J. is, indeed, the correct one.

check for a full 48 volts at the terminals that connect to the meter with a voltmeter. A bad ground or excessive wire resistance will fool the meter into giving a lower than normal reading. Or the meter is defective. A digital voltmeter will confirm the actual battery pack voltage.

compare the number on your old battery to the number on the pictured battery

I'm sorry. but I havent checked that yet. just don't have that accurate volt meter or bridge, sorry George

Check that the battery is 1) good, and 2) installed in the correct direction. If it does not turn on automatically when these are correct, then the unit may be faulty.

Hopefully you were smart enough to check the batteries first, DUH! Change out the board I had the same issues.

There is just the 2 red LEDs and 1 green one for the "charge level" indicators, correct? If so then seeing both red and the green LED come on when you push the test button does hint it is fully charged. If this is the first time you've charged it (where it can take 24 hours to charge), then I'd double check that it's full by pulling the plug on the charger and then push the test button again after 30 seconds. You should still get the 2 red LEDs, but probably not the green. If you have a volt-meter you can also check the battery voltage on the jumper cables, full is ~14V with the charger plugged in and without it plugged in it should drop to ~13V and hold there. If you suspect the battery being bad, then the way to test it is with a known load and see how low the voltage goes. For example, I plugged in a spot-light that pulls ~4 amps and a good battery had the voltage drop to 12.4V instantly and very slowly dropped the longer I had it on (like after a minute only dropped to 12.3V). A bad battery instantly dropped to 11.2V and within 30 seconds went down to 10.5V. That's how you can tell if it's really bad.

Yes, here are 4 pix of both sides of both batterieshttp://i.imgur.com/yb0iDxA.jpghttp://i.imgur.com/NEfhN90.jpghttp://i.imgur.com/yhYTjUK.jpghttp://i.imgur.com/bBmJ2Do.jpg

I would say have them send you another one first and return the old one. It may just be a defective item that you received. It happens from time to time. I wouldn't waste my money on a new battery if it came that way.

I have two like this, but they're a little different from each other. I remember once I thought one of them was broken because I had just changed the batteries but it would not turn on. Then I realized it wasn't set to play on batteries or something... I can't remember exactly what the issue was, but it was a very "duh!" moment. Otherwise just get another one - it's $6 crap from China.

try a different store, it's a common battery for both transceivers and the correct battery can be determined by the size of the used one, if you don't have a batt in hand to use for size, use the internet for the latest cross over to common number based on the batt number you have in hand or in the book............... it's no big deal or i'd look up the sizes I am using I bought last week. write again if you really have probs!!

Yes, I just tried it and it works but since those batteries are 3 volts it is hard to know if it is reading it right. It "pegged" out a new battery and I suspect that it will tell you if a 3V is very weak or dead, but not "low" since a "low 3v" would probably still produce more than 1.5v. By the way, this tester has already saved me it's cost in batteries I would have otherwise thrown away.

I have the same computer and I do have the battery charge indicator in the bottom right corner.

This voltage checker is designed to be plugged into the balance plug of a battery.1 cell batteries don't have balance plugs. That said, it is possible using a creative solution to connect positive and negative pins but not ideal.

Uncertain. A colleague of mine received two batteries and (knock on wood) they are still working fine. For now ... I have placed this in my lessons-learned folder labeled, "you get what you pay for". +++ Am in the process of returning them.
