Will it matter if I use rechargable AAA batteries VS regular AAA's?
I am looking at these rechargables and they say 1.2 V,

e2 Rechargeable Batteries | Walgreens

Then I look at these regular old batteries and they say 1.5 V...

Coppertop Alkaline Battery | Walgreens

why is that? Is it safe to use the rechargables? I would like to just buy a bunch of these and a charger but I don't want to ruin my lasers, especially my 50mW when I get it.

Less voltage can never hurt a laser, only over-voltage. The rechargeable batteries have less voltage because they are made up of a different chemical compound (which gives them the ability to be recharged). There can be a slight drop in power from using Ni-MH batteries because of the lower voltage.

Hmm, ok I may try them out and see how they go before buying a bunch of them. I might use freshly charged and bought batteries to compare and see if the laser differs. Thanks.

They ok.
1.2 V.
900 mAh.
Economical power solution for high-tech devices.
The higher the mAh, the longer the battery lasts between charges.
Made in China.


I used them on my x75

The lower voltage is largely a myth too. Under any sort of load, alkaline batteries will drop to under 1.2 volt pretty quickly, whereas NiCd/NiMH cells stay at almost the same voltage throughout their whole discharge curve, and within reason at any current drawn.

Still, if you still want to purchase a laser, i'd strongly recommend something that runs on lithium rechargeable cells, much less problems with bad regulators/drivers there because there is more 'room' to work with.
