Have a weird issue, voltage, ahc? 2010 LX (1 Viewer)

[Everlong]

2010LX, 150km. Sensor lift done in september. No mods, nothing else hooked up to battery besides dashcam. Drove it 6 hours ago with no issues.

Tried connecting to my dashcam to see whats going on outside. Wouldnt connect.
Went to the truck turned ignition on and was screwing around with camera settings for about 5-10 mins. All of a sudden hear a chime, look on display and it says to check AHC. Try to start the truck no bueno, 9V. Hookup battery charger it shows battery at 25%. New battery installed about a month and a half ago. Proper size/type Interstate. Pulled out the charger. Charger hooked up is 3.5Ah, tiny.

Wait 5 mins, try to start it starts no problem every time. Shows 14v while engine running, restarted few times. No issues.

Try ahc, up down, up down, up down. Only shows lo,n but no hi. Goes up and down all the way fine.
After few cycles shows Hi, but it goes into Hi "quicker" by the seat of my pants feeling.
Used Torque app no codes. Could really use TS

All fluids changed regulary

Any ideas?

Time to start cleaning connections. Start with the grounds.

I cleaned battery terminals and cables with grit cloth when installing battery recently. Any suggestions what else to check?

I also yanked on terminals and they are tight, not moving

If everything else checks out ok, I wonder about that new battery. It wouldn’t be the first time a new battery was bad, if that’s the case. If nothing shows up with all other troubleshooting, maybe try a different battery?

Tight connectors can still have corrosion on them.

Update: Battery charged overnight. While engine running voltage is shown just bellow 14v, as it always was. What i noticed when trying to raise the vehicle sitting in the parking lot is that it went up to HI ,but Hi did not light up right away, it stayed in N untill i drove about 50 feet. That never happened before. Tried few more times and everything seems normal.

Does your dashcam connect direct to the battery and therefore causing the drain?

I dont think so for few reasons. New battery. There were times when i did not drive the vehicle for up to 10 days. I drove it 6 hours prior and all gauges were in spots they're suppose to be.
