so i have been using the moultrie power panel for about two years to power my moultrie modem-usually all good. lately i have been having issues with not getting pics and i noticed that the internal charge was low as well as the current charge setting. well, i decided to replace the battery. ordered one from amazon for like 13$ prime. went to install it, took cover off, and hundreds of black ants with their eggs!!! cleaned al that out, installed battery and is as good as new... so these batteries can be replaced and watch for ant infestations!!!
