There is an issue with this idea, I'ts actually better to trickle charge (hold battery at a fixed "float" voltage) than it is to start a 3 stage charge cycle every day, as during the charge cycle the "bulk" and "absorbtion" part of the cycle, the battery voltage is actually above what you need to keep the battery fully charged, and you are really just overcharging it for that time.Quote:

The recommended float voltage varies with battery type and manufacturer.
but generally 13.8 is okay however some go as high as 14.1 (that's the highest I've actually seen)

Thanks Ron, sounds good for the camper over winter.
I wouldn't have seen it otherwise.

Yes, I take your point, except that I'm not convinced it is a 3 stage charger. From reading the manual, it appears that 'pulse' charging only occurs below 10.5V otherwise it just trickle charges. In my thinking, 3.6A is not really bulk charging if the battery is like mine at about 100AH.Quote:

This is probably a good unit, but I probably will not consider it as it needs someone to press the button to start it.
bought one just on the fact that its listed as 3.8A on the box has a battery voltage indicator on it and is cheaper than the cheapest dumb as a post charger from supercheap.
also bought the inhex/torqz bit set, screwdriver set (I like the feel of the handles on them) and 2 bundles of the zipties.
I've just been and splashed out on one of these as well, it doesn't look too bad at all.
Have to wait until this evening to get home and try it out - if you hear of an explosion and a large smoking crater in the Jindalee area - don't buy one!
I'm with you, it's all about the voltage it's floated at, your otherone must have been too high.Quote:

plugged it onto the deep cycle battery (100ah worth) which is a standard Lead acid type battery.
the LCD read a little lower than my multimeter(s) showing 11.5v as opposed to the 11.6v on the meters.
apparently it went to fully charged some time this morning showing 13.8v on the lcd and more or less the same on the meter (I am not going to argue the hundredths of a volt with a sub $30 charger)
Just plugged it onto a calcium battery again showing .1v less than the multimeter with 12.1v on the LCD and 12.2 on the meter.
so far everything has been done with the charger on the car battery setting.
