Yep bummer. But take it as a learning experience.
Ditto on the Thomas Distributing, the matched charger and batts and on the low-self discharge AA's.
For the past year and a half I've been using the Maha low self discharge AA's and their 4 bay independent circuit charger, which handily comes with both a wall transfo and 12vdc car adapter and can do a slow or fast charge cycle. I also use their higher voltage 9.6v rechargeables which require the dedicated Maha charger (4 bay, independent circuits, also runs off 12vdc).
The low self-dischargers have a slightly reduced milliamp hour capacity (they still run my R-09s for 6+ hours) but retain their charge for far longer than standard NiMH, with a shelf-life after charging similar to alkalines which is reassuring.
Importantly, I've had no power failures since switching to the rechargeables, though I still carry spares and still check voltage with a multi-meter before heading out if in question.
