jtfreefly 0 #1 May 6, 2012 Does anyone know what a brand new cypres battery should read at on the countdown? mine just had a new one put in and only reads 6280 in the countdown. Is that right? let me know please Quote Share this post Link to post Share on other sites
SEREJumper 1 #2 May 6, 2012 Good to go. Error code 8999/8998 - Battery voltage is too low, would be displayed if there was a problem with the battery. http://www.cypres-usa.com/english_users.pdf Page 18, Cypres 1 users manual. "Once the switching on procedure is finished, the unit will run through its self-test. Initially the display will show the number 9999, and then a rapid countdown ending in 0. The countdown will take 29 seconds, and will be interrupted three times. There will be a three-second pause between the numbers 6900 and 5700. The number displayed at this pause will indicate the actual battery voltage (e.g. 6300 means 6.3 volts). The second and third pause will last approx. one second each, and will occur at 5000 and 100. These pauses are for technical reasons only and have no meaning to the user.We're not fucking flying airplanes are we, no we're flying a glorified kite with no power and it should be flown like one! - Stratostar Quote Share this post Link to post Share on other sites
sundevil777 102 #3 May 6, 2012 You say it "only" reads 6280. Is that because it used to read higher with the old battery?People are sick and tired of being told that ordinary and decent people are fed up in this country with being sick and tired. I’m certainly not, and I’m sick and tired of being told that I am Quote Share this post Link to post Share on other sites
Abedy 0 #4 May 6, 2012 If the device was switched off for some time you will indeed have a slightly lowered voltage displayed. The reason is some chemical processes at contacts I was told. If you switch it on the next day the reading should be higher. It can go down to 6.1 V after the winter break. Nothing to really worry about - it would show an error message if the voltage was too low.The sky is not the limit. The ground is.

pchapman 280 #5 May 6, 2012 Interesting. Which may be why Airtec says to switch the cypres on and off a few times after installing a new battery. Not that I ever expect a problem not doing so, but it would help get the current working through the battery system. Quote Share this post Link to post Share on other sites

Not that I ever expect a problem not doing so, but it would help get the current working through the battery system. I think that is the reason, indeed. I'm not that good at electro-chemistry but was told that over a longer period of time certain compounds form within the battery that are sort of degraded once an electric current is flowing again. The sort of effect that goes unnoticed until you build something itsybitsytiny that also measures voltage I found the explanation in the Cypres 1 manual: "If the unit has not been used for a long time, the battery voltage shown on the display during the initial self-test can appear to be rather low. However, the voltage displayed does not indicate a discharged battery but it is merely due to certain properties of the battery. The absence of an electric current over a prolonged period will result in the build-up of an internal protective layer which will minimize self-discharge. This layer can be removed by simply switching the unit on and off a couple of times. You will then see that the battery voltage shown during self-test will rise again. Battery failure or low battery voltage will be detected by CYPRES. At the end of the selftest cycle, CYPRES will stop with an error display of 8999 or 8998 and will not assume operating mode. This indicates that the energy supply of the battery is no longer within operational limits."The sky is not the limit. The ground is.

I was lookng for that too, and could not find that. Quote Share this post Link to post Share on other sites
jtfreefly 0 #8 May 7, 2012 I just thought that new batteries typically read 6500 when they are brand new. I may be wrong. But I think that is pretty much reading 6280 when I sent it in to get packed and there was a new battery installed. Quote Share this post Link to post Share on other sites
Bertt 0 #9 May 7, 2012 Mine never read as high as 6500; usually 63xx something.You don't have to outrun the bear. Quote Share this post Link to post Share on other sites
Abedy 0 #10 May 7, 2012 Just seen that the link results in an "illegal download attempt", heh heh. This one should work and provides information about the detail in chapter 1.4 (Page 7).The sky is not the limit. The ground is.

fcajump 164 #11 May 7, 2012 I would not consider it unusual. Among other things, the battery temp seems to affect the voltage. When installing a new battery, I do see a climb in voltage when cycling it through the three recommended times (haven't read the manual lately, but this was recommended to bring it out of "hybernation" if it set on the shelf/frig) JWAlways remember that some clouds are harder than others...
