Mundane topic... AAA batteries for lasers?
Posted 03 April 2013 - 08:47 PM
Alas, it goes through batteries fast. I bought a pack of Costco AAA Duracell batteries a while back, and am already halfway through the package. I honestly don't use it that much, but I find that even after a few minutes of use, the beam has degraded noticably, and at an average star party/outreach event, the batteries are completely toast come the end of the evening.
Does anyone have any recommendations on a quality battery (and I suppose charger) for these things?

Another option is to see if they make lithium batteries in AAA size. Those can have up to 9x the capacity of alkaline depending on which ones you get. They aren't rechargeable though.

I found some lithium AAA batteries at Walmart. I haven't killed them yet so I can't say how much better they might be.

Have you only used your laser in cold temperatures?

Rechargeables put out less voltage, so either won't operate or will produce a weaker beam.
Keep the laser warm, as in an inside pocket, when not in use. This will make the output of the batteries stronger and warm the diode for stronger output.
If the laser is stone cold, warm it before turning it on.
Use the laser when pointing, but not when talking about what you pointed at. I use a green laser pointer when showing the sky to newbies, but it is on only about 25% of the time I'm talking about what I pointed at.

Don't have a laser now and don't plan on replacing it. Just another toy.
