The answer depends on the type of battery charger you have. Modern smart chargers and maintainers are generally safe for long-term connection because they automatically stop charging once the battery is fully charged. In contrast, older or manual chargers lack this feature and can overcharge the battery if left connected, potentially causing damage or safety issues. It is important to note that some automatic chargers simply shut off after charging and do not maintain the battery, which is fine for quick charges, but not for storage. Maintainers are designed to monitor battery voltage and will periodically top off the charge as needed, making them ideal for batteries that will sit unused for extended periods. When shopping for a charger, check whether it offers true maintainer capabilities, which is also referred to as "float" mode. Always read the charger’s description to ensure it fits your intended use.
