Thread: Alternator voltage a bit high?

Hi Searover, I won’t go into details ( as it would mean plugging my own gear as an example ) but in most cases, this has more draw backs than advantages.

Cheers.

Hi Philip, actually it’s the charge current.

Yes I am aware of this.
I have a low voltage cutout on the fridge and deliberately fitted a relatively small wire to the battery, not a starter type wire. the alternator is an 85 amp, so I think that the current would not exceed design for very long.
As I noted in a previous post the charge voltage starts at 13.6 or so when the battery is down at first, which to me implies the current is also limited.
Anyway, the proof of the pudding is in the eating, and it is going very strong after 3 years and 2 months.
This compares to my poor experience with an Optima yellow top which started leaking acid from the negative terminal at 4 years of age and had lost about 20% of its amp hours. I am certainly ahead vs the Optima as the AGM was 1/2 the price.
I mainly went for the Absorbed Power for its energy density ie it juuust fits into the LH RRC cradle and has a 90Amp hour rating( or 95 for a low draw). Where can you get a flooded battery with anywhere near that capacity/size equation?
I am very happy with the result.
