i just experienced the "death" of my first Tekkeon 3450. the unit was purchased in early 2011 and has never had an issue. it was most recently used in late October 2013 with no sign of trouble. i pulled it out of the bag on new year's day to run some home tests, hooked it up to the charger and in about 5 minutes the charger light turned green. it struck me as very odd because the charge only showed three (3) lights when i hooked it to the charger.
when i checked the charge on the battery while still hooked to the charger all the lights lit up showing a full charge. when i removed it from the charger and checked the amount of charge on the battery it was back to showing only three (3) lights. i hooked it back up to the charger and it showed the charge was at 100%.
not knowing if it was the battery or the charger i hooked up a different 3450 to the same charger and it charged normally. i then tried the 1st 3450 with a different charger and got the same wacky behavior as before.
i assume that something went bad with the circuitry, but i have no idea what could have happened. in October the battery worked fine and charged normally. since then it has just been sitting in the gear bag. i guess this is a friendly reminder to check battery status in between uses. if i was at a festival relying on this battery based on it's previous performance i would have been screwed.
