Long Term NiMH Storage
This past winter, I decided to upgrade my ride to a NiteHawk K2 headlamp with a 6 volt NiMH battery pack. Now that the season has changed and we're officially in DST, I no longer need lighting on my commute and likely won't be using the headlamps again until the Fall. The owners manual wasn't very enlightening on what to do with the batteries for summer storage.
1) put them in my parts box and ignore until October?
2) put them in my parts box and fully charge once/month?
3) plug them into the charger and leave them on trickle charge all summer?
This wasn't an issue with the AA style headlamps as I could swap the batteries into my walkman.
