I have a waterbottle mount NiMH based lighting system on my commuter bike (Dual beam 12W flood/20W spot Marwi Kamikazis) with a 6ampH waterbottle NiMH battery. Just curious since I store the bike in the basement, should I take in the battery because it can get cold in there overnight, to about 35°F or so when it's freezing outside. I think I should be taking it in and connecting it to the lights every morning but not entirely sure? Seems like I'm not getting as long a run time as claimed and I'm wondering if the battering is draining during storage. Jay ------------------ HUGBEES! Certified HTF bike nut and mayor of Obscuria.
