 Posted: Tue May 20, 2008 5:22 pm Post subject: Garmin 530 memory battery |
 |
|
Last weekend while flying our Glastar I was greeted by a message on my Garmin 530 ,"Internal Memory Battery Low". When I got home I looked up the error message in the big handbook, it says take the unit to the nearest authorized Garmin dealer and have the battery changed. This battery apparently backs-up the onboard memory which holds flightplans and other user data. Well, I just couldn't resist the temptation to look under the hood to see how "replaceable" this battery is. As I'm well aware, a trip to the Garmin Dealer usually makes a trip to the Lexus dealer look like a kids play.
I found the battery and well its not for the faint of heart, and for those who don't mind watching open heart surgery I've included a picture of my 530 laid out on the table. The battery is a commonly available Sanyo Lithium cell # CR15250SE with solder tabs available from Newark Electronics and others for about $6. The battery is soldered into a circuit board deep inside the unit and also has a little dab of adhesive for good measure. The good news is that although the battery is deep inside the 530, everything inside the unit is very connectorized and modular, about 20 screws removed and a half a dozen connectors disconnected and you are to the pc board with the battery. The battery comes off with standard desoldering techniques and the new battery is installed in a flash.
With the unit all reassembled it was back to the field for the moment of truth. All is well and after reacquiring its location my GNS530 is happy again.
Oh yeah, the original battery lasted just shy of 10 years.

Bob,
You did not take advantage of the WAAS upgrade for the 530 while it was $1500? Garmin pretty much replaces the whole innards with the upgrade. Oh well, next time if you are not so adventurous, try Charlie Blackert at Airport Radio over at Braden (N43). As a Garmin authorized dealer he can do this stuff for an hour or so of labor and the cost of the battery. He replaced the sticking buttons on my 430 a while back.

To top it off, a call to Garmin would have been the order of the day.... to get an estimate, of course. I'm quite sure it would have made your day.

Interesting that the heart of the system is the humble Intel '386 chip.
Also interesting is the extensive use of electrolytic capacitors, which have a propensity to leak when hot/old.
Thanks for the open heart pictures, Bob

Remember the 430 started shipping in 1997 and the 530 I think in 1999.
The i386 (386EX in this case) wasn't state of the art for PCs, but the dedicated embedded function (EX) processor was a good choice for the application. I'd be interested to see what the "W" units are using now. I"m not as brave as Bob to open mine up however.
