Samsung 30Q (Button Top) 18650 Battery For Video Doorbell.
There is currently an influx of (mostly) Chinese made devices that require power in the form of an 18650 battery.
These devices are provided without the battery, and it’s left to the buyer to source the correct product.
Unfortunately the manufacturer supplied specifications are at best vague and at worst completely unhelpful. Our personal favorite is “shart head 18650”. They are referring to a button top battery, but the information is still lacking a discharge rating and suggested capacity.
We have studied these devices, worked with buyers through countless emails and trial and error to find a suitable solution. Our Button Top Samsung 30Q is suitable for almost all of these devices. With a 3000mAh capacity and 15A discharge limit to ensure good runtime, though this may fall short of the (once again) unhelpful and unrealistic manufacturer claims.
You can confirm the requirement of a button top battery by looking at the battery sled. The location where the batteries installed. If the positive connection is recessed from the surrounding plastic and the opposite end is sprung loaded, it is almost certain to require a button top battery.
18650.UK only supply authentic, batch tested and fully EU/UK regulation compliant batteries, complete with a free battery case for storage and protection
This is a button top variant of the above cell. They are designed for use in torches, R2D2 models, lasers, video doorbells and other such devices and NOT for using in vaping/e-cigarette products. There can be a 1 day lead time on dispatch of 18650 button top cells.
