SHTF and batteries

[the86d]

Has anyone tried to run a 3xAAA, or 3xAA flashlight with a CR123 3.7 (4.2 fully charged), or RCR123A 3.0v (is it 3.7v fully charged?) rechargeable?

The rechargeable LiFePO4's I have sitting around might be a good option?
(I have a CR123-blank that I can use as a spacer.)

Does anyone use, or has any tried rechargeable in their lasers/gun-lights?

I use rechargeables in my Streamlight tlr-1s and an old Blackhawk handheld.
No lasers.


Sent using a long string & 2 cans.

I have AA to D cell adaptors + AA to C.
Thet are handy when/if you need to fire up a D or C cell light and only have the AA or AAA.

This. Most Eneloop kits have C and D adapters for use with a single AA.

I try to ensure that everything is AA or AAA powered.

I can keep the Eneloops powered via solar or 12V inverter.

there is one thing you have to be aware the negative spring for d batts is sometimes large and may miss the center of the cell but a little bend with a needlenose pliers often fixed it forever

Though I have only 2 small tac flashlights that uses AAA, the rest of my flashlights are D size user. I'm slowly acquiring rechargeable AAA and D batteries beside the alkaline that I have on stock.

FWIW, if you have an appliance that uses 8 alkaline batteries they are almost always connected in series to make 12 volts. (8 x 1.5)
And if it runs on 12 volts, then you just need some test leads and an alternate 12 volt source.
A few sets of test leads is a handy thing to have for connecting to alternate power sources...

I use a similar set up.

My approach to this:

1. Buy several 6pk of 123's
a. cycle through them throughout the year under standard use with 123 gear

2. Buy several lamps powered by AAA/AA, etc

3. Invested in GoalZero Nomad7 with Guide 10 charger
a. rechargeable aa/aaa's

I used a rotary tool to carve a place in a 3xAAA battery holder out for throwing in a RCR123A 750mah rechargeable LiFePO4 battery, and it is EVERY BIT as bright as 3 fresh AAA's.

Per this: http://en.wikipedia.org/wiki/AAA_battery, it states that an AAA=~860–1200mAh.

I did almost the same thing as this guy, but I have a bunch of RCR123A rechargable Tenergy batts, and 2 3.7 CR123a's, only I used solder and pulled the springs to make a connection, not wanting to place a spring every batt-swap:

I will have to check the run-times...
