2018 Honda Accord 2.0t battery question

my car is having big problems trying to start...very weak crank. I’m guessing it’s the battery. Where is the fluid levels on the battery? I tried pulling on some caps to know avail.

 

welcome to the forum. to access the battery cells, remove the 2 square battery caps that have the decal on top of them. you may have to remove the hold down brackets. also your battery post may have corrosion and needs to be cleaned. when you disconnect your battery, be sure to have the radio code to restart your radio.

 

Modern automotive batteries don't have wet cells that are accessible
They are usually made with sealed cells with a vent tube on the side
(some times no vent tube)
Trying to open the caps or seals on them will expose you to acid battery risk to say the least.
And at most, expose you to the possibility of explosion
It is a risk to personal safety

 

your decal on your battery shows corrosive. have not seen many hondas with dry cell batteries. batteries explode when there is an open ignition such as a cigarette, hot light bulb, torch or flame. acid battery exposure is if you are over rough with the cover and have your face a few inches from the cap. open slowly and have a damp throw away towel next to you to wipe off any exposure to acid. have handled batteries for over 50 years, no explosion have had acid on the hand but with a damp towel next to me, just wipe off, wear goggles for safety always,. if cap is open, service and close, do not remove terminals it may spark.

 

Welcome in,Im with acmech52 try disconnecting and cleaning the terminals ,it could also be a bad cell,Auto Zone or Advance can do a load test on it for free. Good luck.
