Got an LR Ego kit from MV almost a month ago, and one of the batteries died (900mah). Seeing a number of dissatisfied people with these batts, and was wondering what people may recommend as a replacement. Trying to get the batt replaced by warranty, but I dont want this to continue happening so looking for an alternative.

A lot of what defines a battery life is it's actual "life" experience. Some people will charge them up every night and develop a memory into the cell (bad). Some will let them sit around until they are dead and then expect a charge cycle to make things new again (again, bad).

Bottom line is that unless you post the process you used to keep your battery charged for peak performance, anybody that replies to your post is just guessing. And to be honest with you, even those that may take a guess are not being honest with you.

How you treat your rechargeable batteries are a direct reflection of how they will perform.

Hope this sheds some light on a battery life question...

Having a problem with the LR 1.25 900mah myself.
When I first got 'em (recently) I thought they were da katz perjammiez.
Now I'm not so sure.
Charged a brand new ( factory uncharged) on the proper charger. After 2 hours the light went from red to green. used it well into 3 days before the blue LCD began flashing. Put it back on the batt-USB thingamajingy, plugged that into the AC adaptor, plugged that into an outlet and the light remained green. Unplugged, unscrewed, put back on, re-plugged -- still green. Let "charge" for 2 hours anyhow. Put on carto and first push of the button it's still flashing blue. Recharged again. Light stayed green. Same result.

So, do I have a bad batt or a bad thingamajingy? Comments? Input?

Either way I'm peezed awph.

I've gone from thinking this is my vape machine to I'm not so sure about that now in a heckuva hurry.

I spoke with the folks at MV and apparently there were a lot of these with issues. They are replacing both of mine with updated versions that apparently correct the button and 'coming apart' problems.

I would suggest contacting your vendor for a replacement as well.

Have contacted them.
Will add your info now too.

Thanks,

SA

I know that a multimeter isn't the most accurate way to measure these batteries from what I've read, but I put one on an ego-T 1000mah battery and an ego-C 650mah battery that I have. The ego-T (1000nah) measured 3.4 volts, and the ego-C (650mah) measure 3.4 volts. Is that just an anomaly, or are there actual volt differences is these batteries? I can't tell much difference between the two when actually vaping though. They are both about mid charge right now.:confused:

sorry, moving to different thread. this thread is about the 900 :)

A multimeter is the best way to read the voltage and is also the most accurate providing you load down the battery when you take the measurement. Both the 650 and 900 ego batteries will put out the same voltage, it's not an anomily. The only difference between the two is the 900 has greater capacity so it will go longer between charges.

Lithium Ion batteries have no memory effect, which means that you do not have to completely discharge them before recharging.

I don't see anything wrong with the passthrough. You can also get an adapter for your car.
Use the cartomizers for you regular vaping and the atomizer to test new flavors. You are going to get flavors you aren't going vape and it is a lot easier to clean an atomizer. Don't forget to order juice.

Ok cool, It's a bit confusing at first...I got my juices today and are currently refilling my Blu carts...but it's a bi..ch, so I can't wait for my kit to get here...so far i've tried Hummingbird Nectar from KassBass Vapors. Still to try;
V-spot vanilla
Cinnamon Danish Delight, Chocolate cake, Gooey Better Cake, Rice Krispity treat...sorta had a sweet tooth that day.

Sorry, I tried to edit my post, I guess it didn't register or something. The 1000mah battery is reading 3.4volts and the 650mah battery is reading 3.9volts. I know that all true ego batteries should be reading very similarly, but these two are reading different.

The 650 is probably a Riva, not from joyetech.

If you are reading the batteries unloaded (nothing connected), then they can read anywhere between 3.3 and 4.2 volts. Fresh charged will give you 4.2ish and it'll head downward as the battery drains.

The eGo batteries are regulated to 3.3 volts when loaded (atty connected). They won't read any higher than around 3.3ish, loaded down. They do this so that you get the same consistent vape from when it's fresh off the charger until its almost dead. Otherwise you'd end up with great vape on a fresh charge that would slow get worse and worse as the battery drains.

If you want to read the working voltage you need something like this.
510 Voltage Indicator

Otherwise you just checking the level of the battery charge.

Lithium Ion batteries have no memory effect, which means that you do not have to completely discharge them before recharging.

Just stumbled across this thread looking for any hint on why they bother to have both eGo and eGo-T batteries, as so many have wondered before (the boxes for my eGo-T USBs just picked up indicate they could also come in a plain-eGo-branded variant, and lo, the Joyetech site proves they do - kind of surprised they'd bother with two SKUs for the same thing, but it sure is hard to find anything but the -T on the market loose right now anyway)...

Anyhow, posting to reiterate, as you'll find all over here, that rechargeable lithiums don't have a memory effect* but they don't like to be discharged fully - which is why every product using one has a protection circuit that actually cuts it off before you can get close to doing that. Still, the rule is that they actually live their absolute longest when discharged "shallowly" and stored around half charge - How to Prolong Lithium-based Batteries - Battery University - so a battery monstrous enough that you're always charging it before it can blink "dead" at you may stay "good" significantly longer than one you run down to the minimal level the circuit allows constantly.

(This was certainly borne out with the m402s I started with and how I eventually wound up using eGo / eGo-sized parts! That said, the 1000mAh USB is "inching" into stupid-crazy-long territory, so if I were doing my last buy over I probably should've paid the buck or two more for the 900mAh - different vendors - and saved the centimeter.)

*(Even NiCds don't in practice, and the bad advice to fully discharge them is actually a great way to kill them! While it's hard to find anything that actually uses NiCds anymore, anything that seems like "memory" is in practice is more likely to be a confused smart-charger. They're still used - and apparently well suited for - power tools, so per another site's analysis of the situation, "Don't try to drill that last hole!" NiMHs are less prone to being permanently damaged forever if you run them dead once, so the modern crop are a lot more resilient for household AA-type use.)
