Replacement NiteSpecs LR-44 Batteries -- FREE!
Each pair of NiteSpecs includes 2 sets of batteries (one installed, one for later). Over time, you may eventually need more. One battery set contains 4 replacement batteries (CR927 Lithium), for 1 pair NiteSpecs LED lighted reading glasses. As an extra set is included with each purchase of NiteSpecs and they last 50 to 75 hours on average, you may not need these for awhile!
