A post in Trailer Life Magazine's Open Roads Forum
suggested that BW Manufacturing became MagneTek then Parallax
, so that's the series of hardware. That post gives substantial technical detail, but I have no way to know if it is accurate, or if it really applies to Christine's unit.
The converter in my Boler
does not include a charger, so I know that I can't hurt the battery
with it by overcharging
. The optional charger (which I don't have) is apparently a primitive unit which does
risk overcharging if left connected, so instead I charge with a state-of-the-art Vector brand charger, and also have a float-type maintainer, both of which are safe for me to hook up and forget (not that I would forget... very often
In contrast, the description "Power Converter and Charger" means that Chistine's unit does
include a charger, so it's not in the simple-but-safe category; the remaining question is how "smart
" is the charger, and for that a model number would lead to the right document from Parallax - or you can just assume that it might not handle maintenance charging well, and avoid leaving the converter/charger on for very long periods.
I have yet to see a truly sealed
, and unless you paid a big premium, you have a normal flooded-cell battery
, not a gell-cell or AGM. The caps are still there, and can still be removed (to check fluid level) by prying with something like a screwdriver, after carefully cleaning any junk from around them to avoid contamination.
