Battery Types
Automotive Starting Batteries
Purpose
The lead-acid battery you are most familiar with is probably
the starting battery in your automobile. An automotive
starting battery is designed to deliver a large amount of
current for a short period of time (so it can start your engine).
Only a small portion of the battery’s capacity is used to start
the engine, and it is quickly recharged by the running engine.
This type of battery is not designed for repeated cycles where
the battery is almost completely discharged and then
recharged. If it is used in this kind of deep discharge service,
it will wear out rapidly.
Light Loads
If your installation uses relatively low power loads (that is,
power consumption of 300 W or less) and relatively short
operating times before recharging (one hour or less), you can
connect the PROwatt 600 directly to the vehicle starting
battery. See
Figure 5 .
