Battery charger.


I have a VISTA 20P I also have 2 power supplies Altronix (SMP5) Maximum charge current 0.3 amp each.

If I want to increase the charging current, Can I connect in parallel both chargers to my gel Lead Acid battery?

Charger 1 (+) and charger 2 (+) together. connected to battery's (+) pole.

Charger 1 (-) and charger 2 (-) together connected to battery's (-) pole.

Do I in that case have 600 milliamp in charging current?

No..... the alarm panel alone must charge its own battery. Two chargers connected together will fight each other. Another problem is that the panel will purposely disconnect the battery and allow it to discharge slightly as a test to measure its overall condition. A supply attached directly to the battery would upset that test.

If you had a second battery use for aux devices..... you could use the charger on that.
