Versions of the RCR123A batteries

[a2dcovert]

I just think i figured out why people are having problems with these 900mAh tenergy batteries(I just ordered the whole kit). I couldn't for the life of me figure out a reason WHY a higher mAh(900) rated battery would not last as long or perform as well as a lower one(750) even witht he different chemistry. I have figured it out and it's listed right on the back of the 900mAh kit. I will type it word for word:

IMPORTANT NOTES:
1.It is normal that the new battery cannot be charged to its rated capacity when it is being used for the 1st time. To reach full capacity, new batteries have to be charged and discharged 3 to 5 cycles.

So, in essence, what they're telling you is your not going to get anywhere near the 900mAh capacity until 3-5 charge cycles have been completed.

Hey, thanks for discovering that information. I was getting worried reading the earlier posts. I have 8 of those rcr123a's and a charger in shipment right now.

Also from the tenergy website here are the specs:

http://www.tenergybattery.com/index...facturer_id=0&option=com_virtuemart&Itemid=27

Notice the Excess current threshold is all the way at 3.0 amps(typical) 3.5amps(Max). I'm not an expert on batteries, and someone correct me if I'm worng, but I would think that means that 3.5 amps is the max current the battery will supply before shutting down automatically. That seems more then enough to power the Prodigy?

Just got my shipment today and have the first pair charging. We will see how things go. I'm still very satisfied with the stock batteries but soon will need more than 2 sets available. Batteries will always be available, other things to buy have more priority right now.

Please keep us updated as I've been terrified to even try these things with the posts I've seen. Just as an aside, these are the recommended batteries for the 6V configuration on another (will remain unnamed) Commercially available Mod. They apparently have not been a problem at all in this other mod.

Just spoke directly with Josh at Tenergy Inc. on the phone. The 900mAh are perfectly suitable for this application and should last 150mAh longer then the 750mAh LiFePO4's. The only difference is the chemistry. The LiFePO4's are inherently safer(no explosion risk) also they do not need PCB control as the chemistry itself IS the control. The 900mAh batteries are rated the same current and voltage and risk of fire explosion is minimal due to the presence of an onboard PCB. The only 2 possible problems that you may run into with the 900mAh as opposed to the 750mAh is the chance of a faulty or oversensitive PCB and the overall cell life is less(2000 cycles opposed to 1000 cycles). Since the 750 LiFePO4 is chemically controlled, it has no PCB to fail. But with respect to battery life the 900mAh should last longer. But again, as per their product instructions, it takes 3 to 5 charge/dischage cycles to reach the full 900mAh rating on these batteries.

I have report that initial 3 to 5 charge cycles before normal operation is true. My first couple of cycles the batteries acted weird. If I hadn't known to expect it I would have been worried about the integrity of the PCB.

I'm starting to draw the conclusion that the different atty's may have tripped the 900 mAH batts.

I have a few sendansa atty's here that perform wonderfully on the vapor side of the situation but continuously trip my Kensington as well as the other 3v 900 mAH batts.

I'm also using BE112 , and TW atty's.
These do not trip the blue batteries.

Neither of these atty's trip the yellow and grey 750 mAh batteries.

I'm not electrical minded but there has to be a logic to all this.
I have read reports that some atty's trip the kensington, but the cause is unknown.

Just wondering if you are having so many problems with things. Could it be "user error". IMO it is hard to believe you have so many problems that no one else has.

Update, one week using the Li-Ion tenergy batteries (the blue ones). Even after the 2 to 5 charge cycles I still notice the batteries act funny when you first put them in, like it hard to get the protection circuit to release. Also have noticed that these batteries run a lot hotter than the LiFeP04 batteries. I put a heat gun , infared, on the Prodigy barrel and I got a reading of 107 F. The heat is not comming from the atomizer because the atty adapter was reading 84 F, the atty was reading 122 F. I haven't noticed any of this battery heat with the stock batteries. The temp is within the specs for these batteries but it is uncomfortable to use when it is that hot.

So, I still recommend the stock LiFePO4 batteries that Puresmoker sells.
