850xp Battery Issues

So I have a 2009 850xp w/EPS that I bought about 2 months ago. It has less than 300 miles on it and is in excellent condition but I have had a problem with the battery losing charge. I should mention that the battery was replaced at a polaris dealership right before I bought the machine.

So far from what I can tell the charging system is working, I have 14.4 volts across the batter when the machine is running. I also let the machine sit for 7 days and checked the voltage daily and the lowest the battery got was 12.65.

The issue seems to occur when using the lights or other accessories like a sprayer that connect to the battery with alligator clips. After night riding or using something like the sprayer when I go to start it the next day it doesn’t have enough juice. Unfortunately I have not put a meter on the battery at these times to see how low it actually is, I just throw my trickle charger on it and 10 minutes later it fires right up.

I should probably also mention that shortly after buying this bike I installed an LED light bar on it but I really don’t think that could be the issue since I used one of the existing accessory wires that only have power when the key is on.

Any ideas???
