SDPs do not respond to the test voltage. Without a response to the test voltage, a PD connected to an SDP will only have the standard USB-specified current available to charge its battery. The PD may still charge the battery if connected to an SDP, but it must be able to limit the peak current it draws on VBUS so as not to exceed specifications.
However, a general rule of thumb is that a battery should last between 3 to 5 years. It is important to monitor your battery''s voltage regularly to ensure it is functioning properly. According to the car battery voltage chart, a fully charged car battery voltage falls between 13.7 and 14.7 volts with the engine running.
