Useful links. The coin cell that you'd need to power an E-Textile circuit provides 3V, therefore, any LED with a supply or forward voltage of around 3V will generally be OK - please click here for the full listing.
When designing your project it is also worth noting that if a number of LEDs are spread out a long way, then the LEDs furthest from the battery will be slightly dimmer than the LEDs nearest it. Please note that the electronics are not water resistant and should not be washed. So, you've established that you'd like to introduce a number of LEDs to an item of clothing but your first question is: can the item be washed once you've sewn an E-Textiles circuit to it?
The answer is yes , but there are a few extra steps that you have to take when assembling your circuit - the battery holder and any switches must be removable , which is simple enough to do! It should only be the conductive thread and the LEDs that get washed.
Please make sure that you dry everything properly before use. The best way to do this would be to attach the cell holder to a separate piece of non-fray fabric with a metal popper on either end As for the circuit that you're stitching onto the garment, sew two metal poppers where you would have positioned the coin cell holder, like so below. The cell holder is now ready to be connected to the rest of the circuit using the metal poppers.
Join the negative popper in the circuit to the negative popper on the cell holder and join the positive popper in the circuit to the positive popper on the cell holder.
This process of joining the coin cell holder to the circuit acts as a switch: when connected, the LEDs will light, when removed the LEDs will deactivate. As well as acting as a switch, this also means that the cell holder can be removed from the circuit to allow for washing.
The garment with the LEDs and the conductive thread can be washed by hand in cool water. Do not iron the circuit or tumble dry the product. You are advised to do your own wash test of your circuit before adding it to your product. Battery safety: Preventing harm to yourself and others.

CR vs CRThe Important Difference Between the CR Battery and the CR Battery One of the most common questions that we receive from our Microbattery customers is how to determine the correct battery to use for a particular device when presented with battery options that have similar characteristics.
The C in CR lets you know the battery uses a lithium chemistry. The R lets you know that the battery is round in shape. The first two numbers let you know the diameter of the battery and the last two numbers tell you the height. So by following this, you can easily see that a CR battery is a C lithium chemistry battery with a R round shape that has a diameter of 20 20 millimeters and a height of 32 3.
This applies to the majority of coin and button cell batteries but note there are some exceptions, like the CR2 or CRA batteries which are considered lithium cylindrical batteries.
