As Booster has pointed out, occasionally going to 80% DoD shouldn't be problem at all and extra money is likely more wisely spent on better charging equipment and monitoring. If routinely going to...

You don't need your 100% discharge and 100% recharge equivalent cycle theory to come to that conclusion. You can just look at any battery manufacturers chart to see that.

I'll rephrase - is...

Explain how these 100% discharge and 100% recharge equivalent cycles can be used if it is a meaningful measure of battery life. Can you compare your 100% discharge and 100% recharge equivalent cycles...

Using the posted Lifeline chart:

2750 cycles at 20% DoD
1050 cycles at 50% DoD
550 cycles at 80% DoD

If we assume that it is a 12V 100Ah battery then:
2750 * 20Ah * 12V = 660 lifetime kWh...

I type way too slow to keep up here :lol:



I don't think you'll find many who disagree with that very general statement. The point I was trying to make earlier is that the penalty is not as...

How does a computer controlled modern vehicle alternator handle continuous loads like lights at night?

I wonder if the modulation is opportunistic meaning the priority would be to respond to loads...

I don't see how the alternator senses voltage beyond its first (and possibly only) connection point to a battery but would be happy to read any links you can provide.

I was trying to explain that you're likely always at a partial state of charge and cycling the battery in that state. You might get to 90% when plugging in before a trip. Then you use the battery...

It's unlikely that the converter (unless newer 3-stage) or the trickle charger gets the battery full. The same applies to alternator charging particularly if a diode type isolator is in use.

It's...

Booster has been doing his best over the years to get us to think of battery output in terms of ENERGY and to stop worrying about CYCLES.

Take a look at the scary cycle life chart on this 6V AGM...
