Just received a mains battery charger for my Bravo BST 12 HP pump with integrated battery from an online Rib shop (who I will not name as they have not responded to my query yet). The Bravo pump as an integrated sealed lead acid 12v 7Ah battery.
I was expecting a 13.8v/0.8A charger (as per the spec on the Bravo pump/manual) with euro pin adaptor but received what appears to be a generic 12v / 1A PSU with UK 3 pin.
On checking to see if the PSU was giving 13.8v I found that with no load it was actually 18.2v on the pin.
Concerned, I contacted the shop and am waiting a reply from someone technical. I also contacted the manufacturers to get their opinion. Still waiting for that.
Thought I would ask for an opinion on here as I need to charge the pumps battery in time for weekend and cannot really wait for responses that I was hoping to get this afternoon.
Also, how do I know when the battery is charged and does the mains adaptor or pump itself contain circuitry to trickle charge?
If all it needs is a standard 12v PSU and not the official Bravo 13.8v unit I was expecting from the product description, I may get one on Amazon
that has LED's to signify charge state and allows trickle, as long as it won't interfere with any circuitry that may be built into the pump.
I don't want to end up damaging the Bravo pump or shortening the life of the battery.
