If you haven't already done so. Pull the new battery and date it, something everyone should do when swapping batteries. Gives you an idea how long it's been in use. Also helps you trouble shoot the item in question, knowing when it was put in service.
No need to date it, I'll just remember the time I posted about it on AR-15.co and search for this post to find out when I put in the new battery.
