Float and storage voltage set to 13.3. Re-Bulk offset set to 0.3V Approx 1A continuous load.
The charger had finished charging and had changed to Float, then 8 hours later changed to Storage mode (1 on diagram). The battery voltage gradually reduced and at 13.27V the charger kicked in to maintain the storage voltage.
Then the charger switched off (2 and 3) for 3 minutes and then switched back to Bulk.
Can anyone explain why the charger would have switched from storage to off, and then back to bulk? The battery voltage didn't drop below 13.0 for more than 1 minute which is what I think is needed to cause a re-bulk.
