odd battery behaviour

Yikes that stinks. So I have 2 ideas:
When you put them on the charger do you stand there for a few seconds to make sure they are actually going? I only have egos for a backup but sometimes they have to get threaded into the charger juuuuust right to stay charging.

Second thought, are you buying all of them from the same vendor? If so maybe try a diff vendor, or charger from a diff vendor etc.. If they are all from the same vendor tell them about your issue maybe they will be able to offer assistance.

 

It can be your atty too try a different typ ?

 

Well I know spending more money is probably the last thing you want to do right now. But if a different topper does not fix your problem I'd suggest trying one more vendor. I get my egos from myvaporsotre and have not had any issue with the batts.

 

A few things come to mind:

You didn't say where you got these, but it is known that stuff purchased off the likes of eBay and FastTech can go through runs of problems, out of spec batteries, or frauds. (Like 1,000 mAh eGo batteries with a 180 mAh capacity battery inside them.)

How hard are you screwing stuff onto these batteries? Ratcheting devices onto batteries so tight it practically takes a wrench to remove it is bad practice, resulting in pushing the center post on the battery down too far. And among several problems that can result from that is shorting the battery out - resulting in an "always on" condition as you describe until you remove the device, allowing the center post to release and "spring back" a bit in the process. If you cannot unscrew that carto in a single handed operation it's on too tight.

Regarding charging:

Make sure the contacts on both the battery and the charger are clean and dry. These liquids are actually non-conductive and e-liquid left on the battery 510 connector or charger connector can cause poor charger performance.

What are you plugging the eGo charger dongle into? The USB power supply has to provide a minimum of half and amp (500 mA) current for the charger to work properly.

If you bought the correct chargers the ratings plate on it should read:

Input: DC 5 volts, 500 mA
Output: DC 4.2 volts, 420 mA

 

Sorry I'm out of ideas. But if you try a topper from another company and a battery from another company that will at least tell you if it's them or something you're doing. If you feel like spending the cash for a little experiment that is

 

Sound advice provided here but as Rickajho stated, not all eGo batteries are created equal.
