Goolsky 10Pcs Ev-Peak Ga102 Power Display Indicator Charge Marker Record Sticker for Rechargeable Battery

I have lots of rechargeable batteries that I store in little plastic cases (that fit 4 batteries per case). Seemed like every time I went to use the batteries, they are discharged. Hoping these little slide indicators help with that.These stick-on indicators are nice and small. They are 0.9 inches wide x 0.4 inches high x 0.1 inches tall. They have an adhesive backing that I stuck to the battery case. Just got them, so not sure how long the adhesive will hold for, but if they start to flake off, I am sure it's nothing a little crazy glue cant fix.

I'm using them in my laundry room so we know which basket cubbies need to be washed. and on the machine to know if it's dirty, and just waiting for enough laundry to make a full load. they slide back and forth just fine, and they seem to stick pretty well.

This item is extremely useful to keep track of which batteries are charged. I gave 4 stars instead of 5, because this doesn't fit on all batteries. I ended up putting it on the battery case.

Great little marker so you know the state of your batteries. Don't want to grab one that's not fully charged and start to race!!

Great product! Securely mounts to battery. Small enough to fit most 2s or larger batteries. Slide indicator to GREEN after changing and to RED after use. Easy way to not get to the field with discharged batteries.
