Samgung 25R short lifespan?

[Completely Average]

Is it just me, or has anyone else run into a problem with the Samsung 25Rs having a short lifespan?

I my years of vaping I've had quite a selection of batteries. AWs, Sony VTC4s, Panasonics, LGs, Samsungs, and even the dreaded Efest.

Typically I replace my batteries after a year, although I've had my Sony and Panasonic batteries for 2 years and they still last around 80% as long as they did when new. My AWs, LGs, and even the Efests still retained 75-80% of the charge after one year.

However, the Samsung 25Rs that I bought last June are only retaining about 60-65% of their charge after 7 months. Even my tootle puffer wife who vapes an iClear 30S with the 2.2ohm coil at a whopping 7.5W isn't getting a full day out of a charge on hers when they used to last almost 2 full days. Meanwhile, the 2 year old Panasonic still lasts her a day and a half. The 25Rs I've been using in my SnowWolf lasted more than a day and a half when I first got them, but I'm lucky to get a full day of use out of them now.

Has anyone else noticed that the life of a charge significantly drops after just a few months with the 25R? Or am I just unlucky and somehow got some from a bad batch?

(BTW, these were bought from orbtronic, so I know they aren't fakes)

The last set of 25r2’s (blue) didn’t last very long, I blamed it on the summer heat. Bought them last May, they were useless by November.
So far my 25r5’s (green) are doing well. Bought in Oct.

I'm pretty well satisfied with blues and greens I run in my single 18650 mechs. I have a couple blues that are still alive and kicking after 14 months although they do run down slightly faster than new batts--but that's to be expected.

The oldest greens I have show no signs of aging at all since October despite regular usage. The new ones I added into my rotation in December are of course still performing properly.

I don't know how low you run them before recharging but this might contribute to early demise. Personally mine almost never go below 3.75 before getting recharged.

there are too many variables involved to get any kind of accurate life cycle test/rating.Yes you can test in a lab under set conditions and you would need to use the batts under THOSE conditions...Some people are using them in mech mods hitting them hard, some people use them in low draw set ups pulling maybe 3A a puff, some people may charge at 500ma others may hit them harder, say charging at 2amps.Then theres storage, someone who charges a batt and lets it sit fully charged for days or a week will differ from someone who charges it and immediately puts it to use

Batteries keep their endurance longer if they are discharged and/or recharged at lower rates Pushing them to the max in either charging or recharging shortens endurance faster

they may not be fakes but are they used batteries pulled from other equipment? how long did they sit in storage before being sold? they have a date stamp on them but its in code but if you check with the manufacturer you can get a chart to help read that code. these factors and others can effect battery life and capacity. you should only but from reputable sellers recommended by experienced users on ECF. when I first started I made the mistake of buying batteries on E-BAY. they were advertised as new 3000mah batteries but when they arrived I cycled them on my charger and found that the capacity was only 800mah. they were clearly used and worn out even though they looked new (re rapped)

As I said in the last line of my post, they were bought from Orbtronic, one of the most reputable battery sellers around that only gets their batteries directly from the manufacturers.

...Orbtronic...only gets their batteries directly from the manufacturers.

I don't think any retailer of individual Li-ion cells is able to procure them directly from LG/Sony/Samsung/Panasonic/E-One Moli.

I'm dissappointed in them as well. And yes, I have 1.5 year old Efests that are still doing well.

That's pretty much my experience. The blues just didn't last. 7 months old, only being charged every other day (so figure around 90-100 charge cycles), used it my wife's tootle puffer setup which draws less than 3A from them, and they only hold around half the charge as they did when new.

Very disappointing.

Nice to hear that the green ones are holding up for you. Think I'm going to try the LG HG2s and see how they last.

My four green 25rs, and the two I gave a friend, are about 6 months old. Used in single cell mechs, at around 0.3ohm, regularly. And they are still holding nice charges. Haven't actually noticed any signs of aging. Although, having so many devices, they get charged every two-three days, so they are still quite low in cycles.

 

[VapieDan]

It seems the majority is satisfied with them

I also had some blue samsung 25r batteries that lasted me about 6 months before they just stopped holding much charge at all. Thought I got a bad pair as well but did not worry about it because I had others to use. Have some green 25r coming in this Monday to try out with my new snow wolf mini

No Issues (yet) from any of my 3 25R's which are closing in on their 2nd B-day now. Started using those back when the VTC4's got scarce and the Fakes were thriving.
I do prefer, use, and own more LG (HE2 & HG2) than 25R's and now only buy LG HG2.

Disappointed myself .

It's a shame there isn't a lifespan battery test. We know how much charge and discharge they can handle thanks to Mooch, but we don't have any idea how long they last. If I was rich and had nothing better to do I would buy samples of all 18650 batteries and run them through a 100 charge/discharge cycle and then measure their mAh retention. See what their expected lifespan is.

It sucks when you buy what you believe to be one of the best batteries on the market only to find that it has one of the shortest lifespans.

I have 3 from October/November still going strong, and 4 more that were bought about a week ago. I guess time will tell.
