I bought eight of these 2 x AA to D cell adapters:

I tested them out in my Rayovac Sportsman Extreme 300 lumen lantern, which is the primary purpose for why I bought these adapters in the first place. I am using AA eneloops in the adapters.
Anyway, after about three hours of runtime, I took the battery adapters which housed my AA eneloops out of the lantern. The lantern was designed to use 3 x D cells. Two face the same direction, one faces the opposite direction. My guess is the lantern uses the cells in a series instead of parallel configuration. With my voltmeter, each adapter read between .95v to .97v. Then I took the eneloops out of the adapters (6 in total) and I noticed the eneloops were pretty warm to the touch. With the same voltmeter, I tested my eneloops and they ranged from 1.01v to 1.05v.
What is going on here? Are these adapters safe to use? The adapters are an AA parallel configuration, not a series configuration.
