apologies for only replying now..
Not much to add really. The battery is used only as a backup power source for Eskom load shedding (I do not cycle it daily) so it has not seen any additional use in the past month or so.
I did one load test which confirmed the capacity on the unit I received (200Ah)
The battery was charged to 14.1V as per manufacturer spec. and then left without any load for about 12 hours. Then a known load was connected. Ambient temperature was about 20.5 degrees C for the duration of the test. The load consisted of a 230W tungsten security light and one small 4W LED bulb which at 230V gave a current draw of about 20A. The inverter was set to disconnect at 10V. Load was connected at 07:00 (battery voltage just before load was connected was 13.91V) and the inverter disconnected at about 17:03. Total time therefore just over 10 hours (10hx20A=200Ah). Data from the log also indicates that about 208Ah "left" the battery and when charging at 15A (standard rate) about 215Ah "went in". While discharging the battery voltage remained fairly constant until the last 30 minutes or so when it started falling of the cliff.
