The Master Watt A-25 automatic charger is designed to charge the following types of batteries:
-
starter motors with liquid electrolyte (including calcined ones);
-
AGM.
A-25 has protection against short circuit, against incorrect polarity connection, overheating, and against high voltage in the network.
The three-stage charging algorithm implemented in the charger allows you to achieve high quality charging in automatic mode and prevents the battery from “boiling.”
The battery voltage is currently displayed on the digital LED indicator.
The A-25 charger is small in size and weight, convenient and easy to use.
Can be used as a pre-start device to quickly charge the battery on board a vehicle. In the "SUMMER" mode, it is ideal for working in uninterruptible power systems, both as the main charger for the inverter, and in parallel with the uninterruptible power supply, if you need to increase the charging speed of the batteries.

OPERATING MODES
"SUMMER"
This mode is for charging:
AGM type batteries;
starter motors with liquid electrolyte at ambient temperatures above 5°C;
other batteries with a recommended charging voltage of at least 14.7V.
The mode consists of three stages:
Charge with maximum constant current until the voltage reaches 14.7V;
Maintaining the achieved constant voltage with a gradual decrease in current;
Storage - maintaining a constant low voltage.
The duration of the stages depends on the initial state of the battery and its behavior during charging.
"WINTER"
The mode is intended for charging starter motors with liquid electrolyte (including calcium) at ambient temperatures below 5°C.
This mode is completely similar to the "SUMMER" mode, with the exception of the limit voltage of 15.4V.
