Gideon, Thank you for your response. I have adapted the strategy of using lithium ions (18650) flashlights and I recharge every 2 months. This had ensured that my flashlights are ready to use when needed. This tact has worked for me so far. I use NiMH (Eneloops) for all my inside use. I may add the NiMH to the car flashlights in the future, if that strategy does not work out. Thank you for everything on your website. It is a great resource.
Did you read the main article that this post was associated? It should explain it all.
How well does the NiMH batteries hold up to hot environments such as the glove compartments of my cars. I try to keep flashlights in each of my cars and nothing is more frustrating than needing a flashlight in an emergency situation and the batteries are dead. I have been using LiOn (18650 rechargables) for this situation and pulling them out for a recharge every couple of months. Would NIMH batteries be better suited to this application?
