Third-generation Eneloops are supposed to hold 70% of their charge after
5 years. I don't mean that. I mean service life.
Back around 1998, I bought 4 each of 2 brands of AA NiMH. They were
still going strong after 10 years of regular use. In each case,
retirement was fatal. If I let a cell sit a year or so, it would
probably never be the same: more self-discharge, less capacity, and
higher internal resistance.
According to Enloop, the same purity of materials that makes
self-discharge low and current capability high, is supposed to reduce
corrosion. That suggests a long service life, but I don't remember
seeing data to support it.
The li-ion batteries in my two cameras have held up a lot longer than I
expected. I suppose one reason is that I don't charge them until I start
to use one and I get a warning. If I don't leave them fully charged, I
guess they don't deteriorate as fast. The day a camera doesn't power
up, I'd have to locate and pay for a new battery. Then I might find out
the problem was the charger. Instead, I expect to throw the camera away
if the battery doesn't work. AA cells seem more practical to me.
If I needed the most lumens from the smallest possible headlamp, it
seems li-ion would be the solution. I'd be tempted to make a compromise
and use multiple AA's instead of the smallest light possible.
looks as if the HL21 is no longer available. If I had a choice, I'd try
the HL22 (the replacement), anyway. It doesn't have as much range, but
it has a wider beam. It's not designed for submersion, but I've never
submerged my HL21.
When I had switch trouble, I was annoyed that the tail piece wouldn't
come off my HL21 so I could clean the switch easily. The HL22 comes
with a spare tail piece. Removing it would probably help me get the
light dry if I were to drop it in a tub of water.
Because of my good experience with Fenix, I might skip the HL22 and jump
up to the HL50.
Amazon prices can change substantially from week to week, kind of like
the stock market.
I like a charger that charges each cell independently. I got the
LaCrosse BC-700 charger. Amazon's asking price jumps around. I was
frustrated at first because inserting a cell was likely to undo the
programming of the one I'd just programmed. The trick is to wait
perhaps 10 seconds, until the display of the last cell programmed gives
I have to get my spectacles and turn on a light to read the fine print
on the display. The most reliable way to tell if a cell is charged is
the rate of temperature rise. Most chargers, including this one, use
the rate of voltage drop, instead. Occasionally, this charger can shut
off too soon or stay on too long. An infrared thermometer lets me
second guess it. If the temperature of a cell keeps going up, it's
charged. If it has stayed cool, it's not charged. This charger is
supposed to shut off a battery that reaches a critical temperature.
Candlepower forums has discussions on flashlights and chargers. There
seemed to be a consensus that the LaCrosse was a good value but Maha had
one with a better display, and it was less likely to shut off too soon
or too late. I don't see it on sale at Amazon anymore.
Fenixlighting.com has the specs of current and discontinued lights.
With my HL21, the light in an 8-degree cone was 6 times more intense
than the light in the surrounding 23-degree cone. The HL22 has similar
intensity (range) but a better spread. That would make it better for
tasks, indoor use, and finding an item dropped in the grass. It also
has a higher color rendition index: 75 instead of 70.
The HL50 has more lumens but much less intensity. It must have a much
better spread, like a floodlight. Sounds like a great work light, and
the CRI is 75.
recommended a charge rate of C/2. LaCrosse recommended 200ma. That was
the default. For a AA Eneloop, that was C/10. That was often too low
for the charger to sense when the cell was charged. If you switched it
to 500 or 700ma, you'd probably be okay. The charger keeps track of the
time and milliamp hours for each cell, so you can see if a cell has been
on too long.
