How many batteries can my boats alternator being hooked up to at one time?
I live on a sailboat and currently have a starting battery and 2 deep cycle batteries connected to a hardwired battery charger and the alternator. I would like to add 2 more batteries. I already have the charger for them hooked up. Can I connect them to the alternator too? Can the alternator be connected to all 5 batteries and charge them while the eninge is runnning? Thanks!
sure you an hook them up wil just take longer to charge them

unless all of your batteries are the same size, type and age I wouldn’t do it. you’ll run the risk of over charging a good battery I would set up a perko to charge each bank separately. This will let you run off one bank at a time, making sure you always have battery power available.

you can but it puts a heavy load on the alternator and will take a long time to charge.

Doing the math how many amps are U using and how may amp alt puts out if a 50 amp Alt 35 amps maybe. if U use 300 amps hr U will be motoring all day . As the Amp hour is rated at 5000 RPM Alt Speed and Your little Diesel will only turn up 1500 RPM>using the pulley size difference. Saying the Alt only turns around 2500 RPM maybe so half the Alt is not being used as the RPM is to low.Have been doing this 4 many yrs. Best to keep the battery’s supply with in your charging range.Or U will be complaining why are my battery’s always going dead.Your charger U hard wire only work with a Generator or shore power. Then U don’t need all the battery’s

You cannot charge batteries with different internal structures in the same circuit without damaging some or all of them. A starting battery is designed to provide massive immediate current to spin up the main engine for starting, as the engine starts the alternator kicks in and runs the entire electrical requirements of the circuit and replaces the 5% or so of power the start sequence drew from the battery. The alternator will only trickle charge the battery past 70-75% charged and this is fine for all temperatures and normal starting requirements.
This starting type of lead acid battery has a lot of very thin plates to maximise the surface area in the electrolyte and is rarely charged past 75% - but if it becomes seriously discharged past 50% it rapidly deteriorates and will quickly be destroyed. This type are never intended for any long draw and do not cycle well. Charging rates are limited as the fine structure requires care to avoid over-gassing and plate fretting. "Deep cycle" lead acid batteries are very similar in construction but use very heavy plates, and less of them. They are designed to allow long gentle discharge cycles - they are unable to provide the high currents of starting batteries and with high internal resistance they require gentle charging regimes for long service, can provide hundreds of full cycles if cared for but will last longest if floating in the top 20% of charge. Again this type cannot be discharged past 50% without running into problems of sulphation and plate destruction. Not made for vibration. Combined "marine" types are just a less shallow cycle internal structure with additional screw terminals. Many high quality lead acid wet cells use special recombinant structures to keep all liquid internal, so no vents - BUT these require a very careful charge system to function correctly.
Absorbent Glass Matt batteries were developed for Military use in the early eighties. This type have very low internal resistance and are capable of extreme discharge and charge currents, most are rated around 500 full cycles although top end types are twice that. Pretty expensive but tough as and fully sealed. Will cope with insane impacts and vibration. Can discharge to 80% plus so gives tremendous reserve compared to older types.
GEL types are the industry standard. Industrial rated traction batteries can accept reasonably high charge rates, can deliver both high output currents and slow very deep discharge levels (80% plus) and cycle hundreds or even thousands of times. They are expensive to buy but give very high energy density for a very long time if cared for. Will happily start big diesels and run your fridge for a week.
If your standard alternator is working fine just leave that for the starting battery perhaps and fit an appropriate second high output alternator for house batteries. This should be managed with a good control circuit to provide the highest input into the batteries whenever the engine is running. Batteries should be interconnected using Voltage Sensitive Relays so the switching is invisible to the load and charging systems.
If batteries are in parallel the alternator will see one large battery - just don’t combine types! If the alternator is turning too slowly it is not the original one and might be from a different engine. An alternator turning at 2500 rpm will deliver most of it’s rated output - after 3000 not much more so I would not worry about that. The limitation is imposed on the alternator by the stock regulator/rectifier, which is very basic, and set up for power supply - not charging as it’s primary function. So if you are trying to charge 400 amp-hours of battery bank that is 50% discharged with a stock alternator of 35 amp rating - you will need about 2 full days of constant engine running to get close to 100% charge as the alternator will drop it output beyond 70% charge. Direct charging is far more efficient as long as the batteries are monitored and the voltage/current is limited at the right moments.
Specialist designers create and fit systems like this all the time. There is a cost though if you want it to work - the materials are not cheap, and a lot of time and thought goes into the individual design. At the least a full and honest power audit is required to establish what is needed in the first place, and then the complete system is designed around this to ensure it can deliver the required output reliably and safely.
Good luck.

Marine alternators are designed to charge 1 battery at a time. You need to add a battery isolator system for multi battery installations. You may want to consider increasing the size of the house bank batteries, rather than the number of batteries, this will save you big bucks on the isolator.
