I find it incredibly wasteful that most Maglites aren't designed for modern lithium cells, instead using alkaleak primaries that have a habit of prolapsing their contents out and ruining the light. That's also an environmental nightmare.
I do keep a Skilhunt E3A on my keyring which I DO run off a single alkaleak as it's something that gets very little use (cell will last me all year). Yeah, that's wasteful, but not as bad as throwing out several D cells.
I think leaking batteries are more of a user problem than a Maglite design problem, given that rechargeable NiMH cells are inexpensive and readily available!
Maglite wanted their products sold in Home Depot, Lowes, Wal-Mart, etc . Those places would never touch a lithium based light like a Convoy etc. Too much liability.
Don’t forget the flashaholic community is very small compared to the entire population of flashlight owners.
I still have and use my first two “upgrades”. Both are 2C Mags, with 3*CR123 (for 9v) and 7v PR-based incandescent bulbs. If I stop caring about CRI, I can swap in a 6D LED for runtime.
Beautiful beams, incredible shelf life, easy to adapt to batteries & bulbs in the field.
I have LSD NiMH cells in my D cell lights (three 3D and a couple of 4D). Too bad I never found any Eneloop “true” D cells. They all have LEDs. Including one with an SST90 and 8 level E-switch, good for 1550 lumens OTF. With the big AL focusing reflector and UC dual coated lens, great runtime with the 10 amp hour NiMh “D” cells, it gives a lot of the current lights a good run. But yeah, it is huge…
I have Eneloops in all of the Two AA lights (all with clicky tail switch and LED conversions). Fortunately I only had a mild case of Alkaleak corrosion in a two AA light early on. I was able to clean it up and it works fine. But I learned my lesson.
I have something over 10 of them stashed around the house and in the cars for backup. Good little lights for what they are.
Time moves on. The lights I use the most now are things like the TS10, Sp10 Pro, or Tool AA…
I loved Maglites and trusted them exclusively while caving… in the 90s. I really did my best to hang on and resist change. I just couldn’t. My last old school Maglite died to alkaleaks a few years ago. It was my fault for leaving them in there.
That prompted me to give them another chance. I got an LED version in their then-recent Spectrum series. Compared to cheaper lights from Convoy or Sofirn, it was garbage. I was very disappointed and haven’t since thought much about them.
