I have the haze agm spec. sheet in front of me, the one hour capacity is 66ahs.
The maximum charge current is 21.4amps, does this sugest that the maximum discharge current should also be 21.4 amps?
My chargers do not have temperature compensation,could this reduce battery life?
My chargers may not have the correct charge profile, could this reduce battery life?
I've now found the correct spec sheet like yours........ http://www.hazebatteryusa.com/s.nl/sc.15/.f
........and they do spec the C1 rate at 66ah so in theory you should be able to take 66amps for 1 hour from them.
They do mention optimum charging on the sheet.
Battery Charging: Haze recommend the following charging profile to optimise cycle and battery life. Charging Voltage (max) 2.41vpc Charging Current Max 20 Hour Ah / 5 e.g. HZB-EV12
100 = 98/5 = 19.6A. It is recommended that the charging voltage be switch to Float (2.27-2.3vpc) when the battery is fully charged. (The above parameters apply to 20-25 oC
Certainly if your chargers are taking the charge voltage above 14.46 volts (as it does say this is the max) then you will be doing damage to them.
AGM's do require to be generally charged fairly carefully so not to gass them to hard.
