Hello people, I've placed an order on the following laser: www.rayfoss.com and cant wait to get it. I do have a few questions regarding usage and battery charging. What would be the best way to use the laser in order to maintain it for as long as possible and what is the best way of charging/storing the battery. Also, any tips would be much appreciated. Thank you!

The Li. battries can be a pain if you get cheap ones. (unprotected)
Which is what your laser will have in it, cheap ones.
No 1. Go to e-bay (or other) and buy a couple, good protected, 18650's (stay away from any brand of battery with the word fire in it, IMHO) Expect to pay $10+ each for good ones!
Here's a link to some good ones,
AW 18650 Protected 2200 mAh Rechargeable Lithium Battery
Eneloops are very good also. Edit: just did a quick search, can't find any 18650 Eneloops{May not be available}
No 2. If not using protected ones, never let the voltage drop below 2.5V. Check your batteries after 5 mins. of use, then 10, etc. This will tell you how long you can run your laser before the batteries are too low.(below 3.0V=charge time)
No 3. Do not leave your batteries on the charger after the light turns green.
For two reasons, it's hard on the batteries, they have a tendency to catch fire if left on the charger.
No 4. Do not subject your batteries to extreme cold or hot. IE: leave them in a car or sunny windowsill. Don't put them in the freezer, also. (don't ask) LOL
No 5. This one should be obvious, but don't drop or throw the batteries around.
No 6. Don't keep the batteries in the laser when not using it. Even new batteries can (and do) bulge open and leak everywhere.
Number 1 and 2 are the most important.
Good luck with your new laser and just plan on buying some spare batteries for it.
I've gone through 6-7 sets on some of my favorite lasers.
Average number of recharges,=30-40.
You will not get 200 charges out of them,as the battery sellers claim.

Thanks for the useful tips, but do you know if I can find these types of batteries in electronic stores like radio shack or can I only get them online? Also, after how long do you recommend changing batteries? Thank you!

The Sanyo Eneloops are NiMH - not LiIon. As far as I know, they are available in AA and AAA only.

if you get PROTECTED 18650 cells, they will stop working. That's when you know it's time to recharge. Li-ion charge up to 4.2V, generally stay around 3.7 though.

You generally can't find these in radioshack, and I wouldn't recommend harvesting cells from laptop battery packs because they are unprotected.
