10-Pack 3AG4 / 3LR626 / 3x377 Replacement Batteries 4.5V for All Laser Training Cartridges

I need a stack of 3 batteries each time I change out.This is a time saver, definitely

Worked ok a couple were leaking like they were on the shelf too long

The batteries work very well and the way they are packaged made for easy installation with no errors.

Decent product for the price, you get a lot for your money. Battery life isn’t super great but at least you get lots of batteries. Fit perfectly in my laser cartridge.

Even though I knew (thought) I had inserted my individual batteries in the proper polarity sequence, I was having some "no fires" with my "Cheaper Shot laser training cartridge" (which I highly recommend too). When I checked the batteries, I found that the 1st. (lower) battery was flipped over. That battery was also low on voltage, while all the others were still at 1.5 volts each. I'm 76 years old, (with finger dexterity problems) and inserting these tiny batteries in the proper polarity sequence is a big problem for me! These assembled 3-packs of batteries, get rid of one more aggravation in my life!! Also, I dryfire practice at least every other day, so the proper operation of my laser cartridge is really important to me.

As described

Scam. Only 4 of the 10 batteries produced the advertised 4.5 volt out of the box. Three batteries had less than 1 volt. Don't buy.

For the rare times I needed to replace batteries in a specific range tool, it was a bit of a pain handling three tiny batteries. Saw this and thought it was brilliant! The first of ten in the pack was either dead, but the second worked fine...and no more losing tiny batteries as the wrap is very easy to locate on the floor.
