Let's say that you are right and that's not an AGM battery. Then if the car puts out a charging voltage of 15V, then that's way above the normal charging voltage range for flooded lead acid batteries (which should be between 14.00V and 14.5V) as a higher voltage would high rates of evaporation of the battery's fluid which means it will eventually dry out if the fluid isn't refilled (ie. early battery death). AGM batteries normally require a bit more voltage (14.6 V to 14.9V).

Boosting that voltage output to 15V isn't a good idea for the standard flooded battery as that would make the battery start off-gassing a lot and the battery to eventually dry out.

Have you done any routine maintenance on the battery since you got it? (ie. clean the terminals, check that they are tights, put some dielectric grease on the terminals (thin coat only!), and maybe charge the battery)

As for the AGM battery, in theory, you never have to add anything to AGMs as the acid is soaked into the glass mat so adding anything will have a hard time to defuse through the entire cell. Of course, the battery OEMs said the same thing with the current crop of 'maintenance-free' flooded batteries as well. As for the caps, maybe, just maybe, you are reading too much into those caps and it was just an engineering cost savings (ie allows them to use the same chassis as other batteries resulting in a low cost to manufacture).macnut wrote: ↑Jan 10th, 2018 12:56 pmSuggest that we stick to battery-related things only and not get sidetracked into discussions like fuel additives to assist starting in cold weather.
Despite the fact that a lot of GTA people have been replacing their batteries recently because they were not able to start in the very low temperatures,
the fact is that batteries around the world fail from heat more than anything else.
Further editing required in 1st. post:
As Deka is a brand name for East Penn Mfg., albeit their main brand, we should not be implying it is part of their company name.
Their other brands include Intimidator and they also use the Duracell brand name under licence for an automotive line battery.
They go themselves often by the name simply as East Penn, leaving off the Mfg. part, so we can do that too.
Re. the differences between AGM and traditional wet cell batteries, here's a puzzle.
Why does the picture in the link below of East Penn's Intimidator AGM battery have what look like removable caps for each cell? (Scroll down to see the picture.)
Is adding water to an AGM battery an expected maintenance task and if so how do you know when it is needed?
The caps don't have the cross-heads in them that the wet cell Deka Gold battery caps have, but look as they are meant to be popped off.
Also, note that there is no vent provision visible for the AGM battery like there is for the wet cell Deka.

I would suggest adding some information on how to correctly boost/jump a battery

#1 and #2 in the picture are inverted if you're following the steps you described.phantom_911 wrote: ↑Jan 10th, 2018 2:30 pmI would suggest adding some information on how to correctly boost/jump a battery
1.Clamp one end of the red cable (+) to the positive (+) terminal on the battery of the DEAD car.
2.Clamp the other end of the red cable (+) to the positive (+) terminal but this time on the battery of the BOOST car.
3.Clamp one end of the black cable (-) to the negative (-) terminal on the battery of the BOOST car.
4.Clamp the other end of the black cable (-) to some unpainted metal surface near the battery of the DEAD car. This is to ground the connection. Do not connect it to the negative (-) of the BOOST car’s battery.

How was the battery tested?

There's a lot of threads on the 'net that seem very similar to your issue - try googling 'honda civic 2003 battery light'. A few of the threads out there actually found various solutions (ie - https://honda-tech.com/forums/honda-civ ... s-3019040/).
