In other words, if your house battery bank is made up of flooded batteries with an amp-hour capacity rating of 400Ah, the maximum acceptance rate of those batteries would be 25 percent, or 100 amps, the ideal alternator would also be rated at …

Figure your usable capacity will be reduced 5% to 10% due to aging, and you end up with a conservative recommendation of three to four times the original 100 amp-hours daily use. Sizing The Alternator Alternators should be sized at 25% to 40% of the amp-hour rating of the house bank (unless you have major DC loads while the engine is running).

A high-amp alternator's output can be negated by a charging wire or cable that is too small to handle it. The more amperage an alternator produces, the bigger the cable required. A 140 amp alternator, for example, requires a cable from 2-gauge to 00 gauge depending on the length (refer to the Charging Cable Gauge chart in the story).

What Size Alternator Do You Need for Your Car Audio? It depends on the total energy required for your car’s system. An as usual amp needs by the all electrical system of a general car supposed to be- Headlight -10A + Car radio-10A+AC -20A+Defroster -15A.Total =55A. This 55A power, you can get easily from your inbuilt car alternator.

Running for those four hours (50% duty cycle overnight) would consume around 205 amp hours from your battery bank. This means that you have something like 115 remaining amp hours of capacity for other loads throughout your day and you could fully restore the energy consumed by the air conditioner by driving (or idling) for just one hour!

This deep-cycle marine/RV battery is rated for 500 MCA (marine cranking amps) and 80 amp-hours. The 140-minute reserve capacity indicates the number of minutes a battery can deliver 25 amps of current without dropping below 10.5 volts. An interesting rule of thumb is that typically if you divide a given reserve capacity by two, you will derive ...

A rule of thumb is that for a 1 hour discharge rate (i.e. drawing 10 amps from a 10 amp hour battery, or 1C) you will only get half of the rated capacity (or 5 amp-hours from a 10 amp-hour battery). Charts that detail this effect for different discharge rate can be used for greater accuracy.

So I went up from the standard 35 amp Hitachi, first to a Lucas 90 amp one and finally to a Magnetti Marelli 110 amp unit. This last alternator - in use in the Med, with engine runs of commonly 12+ hours, lasted fine for 8 years and onto a second engine.
