First of all, you need to understand what condition the current battery is in. Do I need to change it at all? Using special devices, you can check the charge level and increase it with a low value. We have already written about how this is done.
Worst of all, when trouble caught you on the road. In this case, you can take care in advance by buying reliable starting wires, which are popularly called "crocodiles". If the electrolyte level is normal, and recharging the battery does not give anything and the spark escapes from it faster than your daily needs, then it's time to change the battery. As a rule, this indicates a strong sulfation of the plates, and updating the chemistry is unlikely to help here.
