How can I determine when a battery needs replacement and what is the process to replace it?

To ascertain if a battery needs replacement, monitor for signs such as dim lights, sluggish or non-responsive low-voltage electronics, even after sufficient charging time. A voltage meter can also be used on a charged battery; a healthy battery will indicate over 12 volts, while an unhealthy one will be below 11.6 volts. In case of repair or replacement, the battery must be removed. As Tiny Heirloom installs batteries in easily accessible locations, we strongly advise contacting your local mobile RV mechanic to undertake the repair or replacement.
