I have a Blue Smart IP22 12/30 charger connected directly to a 180Ah leisure battery (lead-acid). Went camping with it for the first time last night and noticed that when connected to shore power and using devices connected to the battery that the battery was draining and not being topped up by the charger. Using a Renogy 500 meter showed that the battery had lost exactly the amount of power consumed by the devices, but the charger showed the charging status as “float”. Charging status was set to “normal”. It did fully charge the battery overnight though so there is power going to the battery.
Any thoughts?
