again where are you people getting the idea it is venting into the boot?
I can’t speak for others but Century’s own web site isn’t very good at providing specifications for a specific battery. So they are not doing themselves any favours. In this case they state that their DIN65LH MF has a central venting but don’t elaborate where the vent port is located (left, right or both) and whether any port adapter is supplied to connect battery and vent tube. I’ll blame Century for any confusion due to a general lack of info
..you are being told these cool stories by people invested in you buying the acdelco replacement and if you want to fall for that bs thats fine...
Hope this wasn’t directed at me
All I can say is that I have no vested interests in seeing any increase in any OEM part sales for any OEM. I’m a fan of the cheapest available part that will do the job to spec. Heck, even if a cheaper after market part won’t last as long as a higher priced OEM part, I don’t have a problem with using such as long as this shorter life is known up front so it can be factored into the cost equation
... but again the original comment i replied to was "you must use the factory battery" which is not correct...
The actual quote was “you
must use the factory recommended sealed calcium battery” which you interpreted as you must use an AC delco battery. I can see how you interpreted it that way, so yes, I probably should have worded it better. Such is life...
As is, I only wanted to clarify the VE/VF uses a clever computer controlled charging mechanism to keep batteries in an optimum state of charge. And for this reason one can’t use old knowledge to look a battery voltage within DIC and work out how healthy their battery is. And I also wanted to convey that this charge system can’t be customised for different battery chemistries, so one must stick to a battery using same chemistry specs as the factory battery, if they want optimum battery charge control that such a system provides.
..the century battery for the vf is specified by them and comes with a 10 year warranty and imo they last longer than the acdelco junk the vehicle comes with.
The battery
you linked to only showed 2 year (24 month) warranty so not sure where the 10 year warranty comes from? I’d be happy with a 10 year battery warranty
All the information i can find points to all of the century flooded smf batteries being calcium which is what makes them properly "maintenance free" with a suggested absorption charge voltage of 14.8v but that is on a charger not in a running vehicle so i would expect a slightly higher voltage in the vehicle.
0.7 volts greater? Admittedly the 15.5V desulphation mode doesn’t run very long so maybe that’s ok (I’m not a battery chemist/scientist).
The difference between the 2 batteries is the factory one made with lead calcium silver alloy and the century is made with lead calcium alloy but both are calcium type flooded batteries and they both will vent outside of the vehicle.
Great info, if only Century (and AC Delco for that matter) could get off their arse and make it easier for potential customers to find such pearls of information, that would be great
Obviously, some stage down the road, I’ll need a new battery so I’m curious what your findings are with the Century DIN65LH MF batteries length of life?
