Longwood50 Posted April 20, 2022 Share Posted April 20, 2022 Around the house I have several devices including solar cell lights, rechargeable flashlights etc that use 18650 size batteries. Does anyone make a decent 18650 battery? Most of mine came with the rechargeable solar cell light or flashlight but I have purchased some additional batteries online. They are all lousy. I can use the flashlight for only a few minutes two to three days in a row and then it has lost its charge. The same is true of the solar cell lights. Despite the fact that the solar cell light only triggers when activated by motion, unless it is a really sunny day, the battery does not retain enough charge to fully power it. If there is a good brand, please let me know. I have tried some that were advertised as Samsung but online you have to wonder if that was really true. Here is a picture of the type of battery I am referring to. Link to comment Share on other sites More sharing options...
Crossy Posted April 20, 2022 Share Posted April 20, 2022 "Alternative Energy" is the best place for battery info, moving there. But 18650s on the online selling platforms are an absolute nightmare, more carp than good stuff! 2 Link to comment Share on other sites More sharing options...

Popular Post alanrchase Posted April 20, 2022 Popular Post Share Posted April 20, 2022 Panasonic NCR18650B 3,400mah batteries seem to be ok. Don't buy any batteries that claim to be more than 3,400mah because they are likely fake as 3,400 is about the maximum capacity at the moment. 5 2 Link to comment Share on other sites More sharing options...
Popular Post nrasmussen Posted April 20, 2022 Popular Post Share Posted April 20, 2022 (edited) I have recently bought some batteries from this Lazada store: VapcellThailand. Battery capacity was as specified. To make it clear: I have a battery charger that can measure the battery capacity and if not as specified I return the batteries.

bluejets Posted April 20, 2022 Share Posted April 20, 2022 I use the ones from Hobbyking as they seem to be reasonable quality and weigh in at around 45grams which is good. Plenty of junk around that's for sure. Prior to the HK stuff it was pretty much a 50/50 gamble. Bit of short supply at present. Link to comment Share on other sites More sharing options...
KhunLA Posted April 20, 2022 Share Posted April 20, 2022 Anyone considering 18650s and size/space isn't an issue, you may want to move up a level or 2. https://www.batterypowertips.com/18650-21700-30700-4680-and-other-li-ions-whats-the-difference-faq/#:~:text=The 21700 has about 50,on the internal cell construction. 1 Link to comment Share on other sites More sharing options...

While the advertisers think they will sell more that way, in reality it's just a tipoff to knowledgeable buyers to avoid them. Link to comment Share on other sites More sharing options...
dlclark97 Posted April 20, 2022 Share Posted April 20, 2022 I buy 26650 Li-ion batteries at ProDive Imaging. 4th floor Manee Tower in Bangkok near Chit Lom BTS. Perhaps they also have the 18650. Prodive Imaging Official | Home page Link to comment Share on other sites More sharing options...

OneMoreFarang Posted April 20, 2022 Share Posted April 20, 2022 I bought some from this shop. They seem to be alright. But to be fair I don't have much comparison. https://www.lazada.co.th/shop/vapcellthailand https://www.vapcelltech.com/ Link to comment Share on other sites More sharing options...

The problem is that many of the batteries which are sold have brand name stickers on them. And that's about the only thing which they have in common with those brands. It is very difficult to find out which of the batteries are "real". 1 1 Link to comment Share on other sites More sharing options...

There are so many batteries with brans name stickers out there. I find it difficult to impossible to find out which are the real thing. I like to listen to your experience if you have any with this supplier and their batteries. Link to comment Share on other sites More sharing options...
snowgard Posted April 21, 2022 Share Posted April 21, 2022 If you don't have a meter to check the battery capacity, you can also weight it. In trusted shops of your home country you can see the original weight. Almost all FAKE BATTERIES are much lighter as the real one.
