Well, if you plan to keep it always connected, a voltage divider has the disadvantage to draw a little current continuously. If the arduino is connected to the battery too, this current is negligible; if, on the other hand, you are powering the arduino from another source and you want to store the battery for long times, I suggest you to use also a transistor to

A lead acid battery supplies current through a chemical reaction between its components. The main components are lead dioxide (PbO2), sponge lead (Pb), and sulfuric acid (H2SO4). According to research published by the Journal of Power Sources in 2019, a lead-acid battery can lose approximately 10% of its capacity for every 10-degree Celsius
This effect can shorten battery life and efficiency. Thus, temperature significantly impacts battery voltage and overall performance. On the flip side, low temperatures hinder these reactions. A lead-acid battery in cold conditions may display a voltage drop, often falling below 12 volts.
A lead-acid battery can get too cold. A fully charged battery can work at -50 degrees Celsius. However, a battery with a low charge may freeze at -1 degree When temperatures drop, the battery struggles to provide the necessary electrical current to crank the engine, which can lead to frustrating and inconvenient situations.
