Upgrade micro chip for model 109 Lithium Charger.
This micro chip is easy to install. It plugs into the socket on your circuit board and upgrades your charger to the latest Software Version 2.0 released in March 2008. Remove the four screws which are holding the charger together. Flip the charger over into the gray tub. Use needle nose pliers to carefully remove (wiggle upwards) the old chip from its' socket and carefully press in the new chip. The small notch on the chip faces the middle of the charger, not the edge of the charger. If it goes in backwards no harm will be done, but you will see black squares on the display. You may use a Popsicle stick to guide in the feet and press gently. The new features:
1. Cell Count is Locked in as soon as battery is detected.
2. Time out is increased from 1 hour to 10 hours.
3. Amp Hours are increased for 9.5 to 95 amp hours.
4. Now you can charge large packs in parallel.
5. Discharge stops at 3.2 volts per cell.
6. Charging stops at 4.2 volts per cell.





For full instruction sheet please see Astro part #109 or #109d LiPo Battery Charger.
When you purchase a new 109 or 109D charger it will have the new chip installed already.
