I have a buisness application that I'm using a .8 amp Sla battery as the power source. The application operates a 12 volt motor and small receiver/transmitter. The standard 500Ma float charger will charge the battery up to 12.6v to 12.8v prox. This charge will only operate the system for about 1/2 the time I need.
For the proper "operating time" and "immediate power" requirements I need the beginning voltage of the .8 amp battery to start at a full 13.4 Volts prox.. When voltage drops below 11.5v the unit stops working and the battery is recharged to a full 13.4v prox..
In the summer this is done 2 to 3 times a week. During winter the system is idle.
My question is this.
In the long haul (expecting a 2 to 3 year battery life) will it damage a Sla Battery to charge it to a full 13.4v rather than the lower voltage (12.6 to 12.8v recommended)?
