Agreed. That’s why I’m going to ask @Mandrake50 (who won the other flashlight+battery in the same GAW that I did, and who also owns an MC3000 charger) to team up with me for this testing, as soon as CyanSky replaces the much worse battery they sent him by mistake. Surely it will not be as scientific as an @HKJ review, but should be good enough for people wanting to know how good their BL1834U battery is (to say nothing of their flashlight).
