Let's do batteries again!

[Scottes]

Good corrections. Thanks ski.


Here are the Tenergy RCR123A 3v LiFePO4s that I use:
Tenergy LiFePO4 RCR123A 3.0V 750mAh Rechargeable Battery (as low as) $2.79 ea!
With the charger:
2 RCR123A 3.0V 750mAh Rechargeable LiFePO4 Li-Ion Batteries with AC/DC Smart Charger

Good grief !!!

 

[HokieSmokie]

ok then .. I see best charger best batteries ..cr123A ...
What would be the BEST charger for CR2s ? I am guessing there are not any 6 volt batteries PERIOD .. or even 5 volt that would fit in our PVs

I use the Ultrafire WF-138 for CR-2 3.0V: DealExtreme: $11.54 UltraFire 3.0V/3.6V CR123A Charger it has a selectable voltage 3.0 or 3.6 and is sized for RCR123A/16340. If you put it in 3.0V mode and stick the rare earth magnets onto the CR-2 3.0V batt it works great for that. I got this because I don't trust the Since brand cheapie charger normally used for CR2. This charger should not be used for the Tenergy RCR123A Li-Ion though, those are special and need a special Tenergy charger.

...and stick the rare earth magnets onto the CR-2 3.0V batt...

Could you elaborate on this? Why would one do this?

 

[forcedfuel50]

This is the CR2 charger i've used and haven't had any problems with it. No adapters or magnets needed to charge your CR2's either, just put them in!

DealExtreme: $5.48 CR2 Battery Charger

Heres a link to the CR2 batteries too:
DealExtreme: $3.82 Rechargeable 3V CR2 800mAh Green 2 Packs


And heres the protected 14500 900mah batteries for 3.7 volt vaping in the super six-
DealExtreme: $4.75 TrustFire Protected 14500 3.7V 900mAh Lithium Batteries (2-Pack Blue)

The WF-138 charger is sized for 16340, so its battery slots are 34 mm long. CR2 batteries are 27 mm long (they are also known as 15270's). To make the connection in the charger, you need 7mm of some kind of spacer material. Rare earth magnets are conductive and easy to stick on the end of a battery, so it's a fairly common practice to use them. I bought 100 of them for 6 bucks from DX: DealExtreme: $5.96 Super-Strong Rare-Earth RE Magnets (8mm / 100-Pack) Suitable for Extending 18650/CR123A Batteries

You don't have to do this, I just had read alot of comments about the flimsy build of the Since brand chargers and figured the WF-138 would be handy since it will also charge 16340's at 3.6V. I already have 4 battery chargers, 2 cell chargers, and 2 bluetooth headset chargers on my desk, so I opted for a 2-in-1 device with a bit better build quality.

Aah. I just bought a couple of aluminum spacer blocks that do this.

That'll work. I like the magnets because they're handy. The Tenergy 18650's i use don't have a button top, so I use a single magnet on them too, otherwise they are a pain to charge because the contact isn't 100% there in the trustfire TR-001 charger i use for them.

I am also planning to make a magnetic knife rack out of them too

Any views on the best 14500 charger?

imho, wf-139.

 

[emonty]

I use the TR-001 (Trustfire), cheap and works fine for my 18650, 10440 and 14500 batties.
Even got one hooked up in the car

I am no expert and hope some of the more knowledgeable members will jump in here.

I have looked at this one and have a concern. If you read the reviews it appears to continue a trickle charge after it shows green. I don't know if this is really an issue but have read these batteries shouldn't be trickle charged.

Any thoughts from the rest of the members?

Super T2- 16340 in 3.7 volt mode. No 6v option on the T2

That is a great deal but does not fit any of the Supet T line.
These 123a batteries are 3 volt and we need to use the 3.6/3.7
For 3 volt, we will be using CR2/15270s

Also, the mAh is 200....I read somewhere that said you can't trust what a batt says its mAh is. It's hard to know what's the truth.

[emonty]

yup, but for the DX price you can't beat it, if stated 2400 MaH and you get 1900, it is still a great price. Buy enough, that way you can swap....
