My LASER came with a rechargeable NiMh battery and charger. Should I use Lithium batteries instead?
A. No. If your LASER came with a rechargeable battery, it was designed to use that type of battery. You can use a Lithium battery of the same type and voltage if you want to, but it will not affect how your unit performs. If you are taking the LASER into a harsh environment – especially in extremely cold weather, you should carry a spare Lithium battery, especially if it is dangerous terrain, or if you anticipate using the unit for rescue signaling.
