Yes. VRLA batteries have weak side called selfdischarge. If you disconnect fully charged battery and leave it, it will discharge. speed of discharge depends of storage temperature. As temperature is higher the discharge will be faster. If you charge VRLA battery every time when it goes below 12.20 V ( speaking for 12 V battery), it can be store up to two years with no damage on battery.Worst thing for battery is to leave it uncharged.
oh nice not too overly expensive then. btw is it normal for a new pair of unused batteries to simply die like that ? i never used my unit. But all this while the batteries had been plugged in tho.
I got this exact same unit in '08 and it has been sitting in a closet ever since, stupidly i forgot to unplug the battery back then and now the battery is dead i guess, it displays an error when ever i connect it now. how much did a new pair cost you ?
