Default 3.2v battery for 3.0v required laser

My 150mw Endeavor takes 3.0V cr2 batteries and i recently purchased two 3.2V rechargeable cr2 batteries without knowing they were 3.2V instead of 3.0V. I was wondering if it is safe to use these 3.2V batteries without harming my laser?

"3.0V" lithium batteries should be 3.3V when new, anyways.
It's just like how "3.7V" batteries normally operate at 4.2V.

Default Re: 3.2v battery for 3.0v required laser

First....double posting is a No...No...
You can easily use the [EDIT] button on your Post
to EDIT or ADD info to your post.

Secondly CR2 batteries (as far as I've seen) only come
in 2 varieties ..... 3.0V or 3.6V... I have yet to see a 3.2V
CR2 battery.

BTW.. a fully charged 3.0 Volt battery puts out 3.6V
and a 3.6V battery puts out 4.2 V...

I got a LiFePO4 cr123 that is 3.2V. Its peak is 3.6Volts.

In phycics,if the power is less than 20% over the rated voltage, it's Ok. so just do it, it will work well. But the life span of your laser may be shorten to some uncertain extent
