Thoughts on handheld Aviation radios (ICOM vs Vertex-Standard)
WallMart has Eveready NiMH 2300 cells, about 11 bucks for 4. I don't think that is expensive, for how many charges you can get out of them. And you are right, they kick alkaline's As* ! :-) I bought an 8 pack from Wally World for appx $17 about 2 weeks ago. FYI.... The previous versions offered last year were 2100 mAh. Some say they are not good batteries, but I have had great luck with them. One will go bad at random, once in a while, but the rest go on and on. As far as the self discharge goes, I have never scientifically charted them, but I have the feeling that they are not as bad as the 1% per day that some people claim. I've never lost a single NiMH battery in 5 years of use. Call it luck or just old fashion TLC. g As to self discharge... Ambient temp is a most important variable. 20 to 45% loss in 30 days is typical for NiMH cells according to http://www.panasonic.com/industrial/...H_Overview.pdf Ta-ta.... Barnyard BOb - |

This brings up an important point: If the radio is to be your only one, then you want rechargable batteries. That was a major reason I bought the Yaseu (now Vertex). If for backup, then probably alkalines, though from my readings here I realize that my information may be terribly 20th century. That was one reason I sold the Sporty's: it ate batteries. all the best -- Dan Ford ++++++++++++++++++++++++++++++++++++++ If anything eats batteries quicker than a Garmin 295 or a dead short, please show and tell. g Barnyard BOb - from the Show Me State |

Last year I bought some Nexcell 2.2Ah AA's off Ebay for $.99 each (about $1.15 with shipping). I expect higher capacity cells could be had for the same price now. I've never lost a single NiMH battery in 5 years of use. I haven't lost a cell for a few years, since I started using a good microprocessor controlled charger. Cheap chargers will either undercharge them or make them die young, and cheap fast chargers are even worse. -Dan |
