Tenergy 3v batteries

[a2dcovert]

Guys
i have some very good charger models that have nothing to do with tenergy.

What i am trying to warn you of is the following :
1. charge both tenergy 3v batteries.
2. measure them when charged , they should read 3.2 ~ 3.4 V each.
3. Start vaping
4 after about 30 minutes the vapor production drops or the atty sizzles no more.
5. remove the batteries.
6. measure them again.

The bad battery reads 2v or thereabouts.
The one that is not defective still reads above 3 v.

The prodigy cannot perform correctly with one good battery and the other one that loses its charge over the first 30 minutes.

I am trying to say that you need to find the bad ones and throw them out.

I think the batteries that are shipped with the Prodigy are not fully protected. Here are the batteries I just bought:

Tenergy RCR123A 3.0V 900mAh Rechargeable Li-Ion Battery

Features:

• Rechargeable CR123A Li-Ion Batteries with 3.0V working voltage and 900mAh capacity.
• Tenergy RCR123A can be recharged up to 1000 times.
• 1 RCR123A Li-ion = 1000 CR123A Primary Cells
• Replace the most of CR123A primary Lithium battery for a digital cameras and most flashlights.
• Internal voltage regulators. Initial cell voltage of 3.6V switches to 3-3.2V within 12ms.
• Full PCB protection against: Over-Discharge, Over-Charge, Short Circuit & Over-Current along with voltage regulation.

If a lithium battery is allowed to discharge below it's lower limit damage to the battery will result. The listing for the batteries that puresmoker ships with the prodigy is:

New Chemistry LiFePO4 Li-Ion batteries:

Rechargeable LiFePO4 RCR123A 3.0V 750mAhBattery
Life cycle: 2000 times (Traditional Li-ion: 500 times)
Never explode or catch fire
Working Voltage:3.2V and Peak Voltage: 3.6V
Charging cut-off voltage: 3.6V
Discharge cut-off voltage: 2.2V
Please never overdischarge battery below 2.2V/cell
Charge the this battery with LiFePO4 RCR123A smart charger.
Capacity: 750 mAh
Maximum discharging rate:< 550 mA
Maximum charge current: <550 mA
Cell's dimension: 17mm Dia. x 34.5mm H.
Weight: 0.6 oz (18 grams).

How are supposed to know how low your discharge is at any one given time? Since you state that you measured 2.0 volts you are causing the batteries to be damaged. Do this too much and they will die a short death.

Thanks ,Quovadis...I too have had problems with some of them but they were all showing 3.2v after charging so this 30 min. test might be a good way to test which are good or bad!

Now if 4 of mine don't even work in the Prodigy anymore but still show 3.2V..what does that mean??

This may be another issue you are having with the spring coil not touching the batteries properly.

Apparently you need to pinch the last coil in the spring to ensure the last coil touches the battery.

Other than that, it may be your switch which is dead.

I have to say I now own 4 pts and 2 prodigies, and there's no free lunch.
I would rather have to take care of a baby.

Hey Kevin
Thanks for the link, I just got my Prodigy today and am concerned as I've heard there have been issues with the 750mAh Tenergy's provided with the kit. It's not really made clear whether they have overdischarge protection and the note on the website you referenced would kind of indicate they do not. I just ordered the kit from battery junction(900mAh 4 batteries and charger) you linked. Better safe then sorry. Also, they hold more charge so they should last longer.
Thanks again.

No problem, I may be new to the prodigy but I'm not new to batteries. quovadis has a good suggestion about monitoring the battery condition. Any weak batteries shouldn't be used.

I was glad to find a US source even though the China batteries are cheaper.

Thaks Kevin,
I've used Battery junction before and they are excellent!!! Really fast shipping, they are right in Connecticut(I'm in PA) so even ground shipping is fast for me. Also everytime you order they send youa 5% off code for your next order(a small little xtra)
since your not new to batteries, let me ask you(and this does have to do with the Tenergy 750mAh that come with the V1 kit) as I said I just got mine and am right now ,as I type this, doing the initial 3-5 hour charge on the 1st battery set. The charger and batteries are warm, not hot, just warm. Is this normal? I read somewhere that Li ion batteries were not supposed to be allowed to get hot or warm(that it ruins them). Have you had this happen to you? Anybody else? Is this normal for this battery/charger combo? or should I be concerned??? My regular Joye 510 manual batteries never got a bit warm when charging. Thanks again.

The batteries shipped with the prodigy are LiPoly batteries. I'm not sure about the cylinder shaped LiPo as I've not used those before. Normally heat is bad for lithium bats. I don't think slightly warm would hurt, hopefully others will tell us if that is normal for this set or not. Is it possible the heat is coming from the charger?

Oh absolutely, the heats definitely coming from the charger(I'm sorry I should have been more clear about that-it's not the batteries themselves that are getting warm) But it's enough to warm up the batteries in the charger. Is this normal for the charger to get warm enough to also warm up the batteries. Again the only thing I have to compare it to is the manual 510 batteries and charger(both AC and USB and PCC), these never got warm in the slightest. Thanks again.

Update::: Now that I'm about 2 hours into the charging cycle (The light's still red) I'm noticing the warmth is diminishing considerably in both battery and charger(in fact it's almost back to room temp). My guess is the charge is nearing the end of it's cycle and , therefore , the charger itself is drawing less current(thus less heat). Hopefully the light will turn green soon and I'll know all is well. Either that or the charger was defective, fried my batteries, and I'll be waiting until armegeddon for the light to turn green.

what happens if you put a 3V batt into a 3.7V charger accidentally? could that have killed the 3V batts even though they still show a 3.2V charge?

I believe most high performance chargers will put out heat normally. The battery temp range at Batteryuniversity.com says

[FONT=Verdana, Arial, Helvetica, sans-serif]Lithium- ion offers good charging performance at cold and hot temperatures. The acceptable charge range is 0° to 45°C (32°F to 113°F).[/FONT]

They lump all lithium batteries together on specifications.

I've been thinking about trying the 18650 and I use an 801 atomizer. Do you have any experience with that combo on a Prodigy?

Most of the juices I like taste better at the lower voltage. I can bump up the nic to compensate for less vapor per hit. Would be nice to have a battery that lasted all day.

Sorry I don't own a 801 so I cannot say. I am currently using a with resistor switch but I am waiting to order the without resistor; seems they are out of stock since I tried buying one last Friday.

Thanks for looking that up for me Kev, it appears that all is well after all. I had updated my previuos message(about the charger cooling as the cyle progressed) Now I'm at the in between state, where the charger LED is slowly changing from red through yellowish to green(it's almost all green now except for a few photons of red sneaking thru) .I'm gonna let it go the whole 5 hours as recommended by PS for the 1st charge, then let 'er rip, so to speak. Thanks again.
