Battery volts of main and secondary batteries:
Reads Battery volts 10.0-65.0V accurate to ± 0.2% ±1 least significant digit. For battery systems with nominal volts from 12 to 48V. Volts (only) can be read for optional second battery.
Battery system size:
For 12-48V nominal system voltages. Battery system size: 10 to 10,000 amp hours.
Size: TM2025-RV:
3.2 x 4.3 x 1.4 inches, (8.2 x 11 x 3.6 cm) enclosure included.
Use of volts:
It is useful to measure "volts" because it is a basic electrical measure of the battery--or the solar array--or charger. The following table shows what happens to battery volts with lead-acid batteries under some conditions of use.
