NCR18650B are outdated. The have been succeded by NCR18650BF.
NCR18650GA, LG INR18650 MJ1 and Samsung INR18650-35E are currently the ‘best’ batteries.
All 3 are usually offered as ‘3500mAh’ cells.
GA and 35E are specified as 3450mAh ‘typical’ capacity, 3350mAh minimum.
MJ1 and are rated 3500mAh typical and 3400mAh minimum.
In reality, we can excpect them to be closer to minimum than to ‘typical’.
I was able to order 8 of them (NCR18650B 3400mAh button top) for $35.50, from Gearbest.
Shipping took almost a month.
So I’ll let you judge if they are a good deal.
Generally a gold plated board means it is a better quality circuit and most likely seiko. Most cheap protected cells I’ve seen don’t have gold plated contacts.
Hi, I’m using 2 of these protected green batteries to power a Nitecore EC4SW.
I’m wondering if there would be a noticeable difference between these vs more expensive protected NCR18650B based cells from EVVA, KeepPower, Orbtronic, etc.
Or if there are other batteries better suited to maximize safety, runtime, or output in the EC4SW.
I have a feeling this battery will continue to live in for long time it’s a classic. Most edc lights are 3amps and under anyways. They work great in my powerbank. GB has them on sale from to time. The price isn’t always the same from the listing until you click to open the page. The ones I got I played $27 for 8.
Is it OK to replace Samsung ICR18650-26F 2600mAh included in the OEM Laptop battery with the more powerful Panasonic NCR18650B 3400mAh
I’m worried both batteries have different power output and might cause any problems with the laptop.
See the graphs and read the text in the OP.
It’s not a high drain cell at all, so you don’t use it for high drain appliances.
It’s a great battery up to 3 Amperes, but with the high internal resistance you get too much voltage sag when you draw more current from it. The losses are translated into heat = the battery will get warm.
