8-5-12  -- Hangar 9 Angle Meter battery mod / fix 




This meter uses a GP 11A , 6 volt battery, in which it died on me today,
and these are no where to be located locally....  Sure, the hobby shop
carries these but it's about 46 miles down the road, but today is
also Sunday.....


Need a quick fix....   LOL





Battery equivalent to: G11A, MN11, GP11A, A11, L1016, CX21A, CA21, E11A, WE11A.

Nominal voltage of 6 Volts. 38 mAh Nominal capacity. (to 3 volts @ 10 kiliohm @ 20*C)
{4.7 volts minimal (200ohm load resistor @ 20*C for 1 to 2 seconds)}
----Price Approx: $3.95




Here's my solution:


I just soldered wires onto the positive and negative leads on the circuit board right through the battery door in 

the meter,  not even a need to take the meter apart!


I'm running this on 4.8 volts.... works fine.... Original battery is a 6v power source, but it works down 
till the battery is completely drained.... so I know already that it works well below 6v

So, anyways..... I decided to use a 4.8 volt, 4 cell AA pack....
The 4.8 volt pack is approx 6.2 volts after a fresh charge and remains 
right around 5.2 volts to 4.8 volts on the average untill it's ready to be recharged...



The nice thing about this, is that the mod is COMPLETELY reversable by simply de-soldering the wires...  or 
actually I could cut them off where they were soldered and use the original sized battery again......
The soldering was done on top of the circuit board and never interfered with the battery face contacts.... 



However, personally, I'm going to keep it like this since the wire doesn't bother me at all...   <thumbs up!>
