What kind of battery does a Yanmar 36i have?

What kind of battery does a Yanmar 36i have?

I have 2008 36i with Yanmar 3YM30 and Hitachi 60 Amp alternator with 320 Amp hour domestic battery bank. Even when batteries are low I never get better than 22 amps charging and this quickly falls to about 15 amps after the engine has been running for about 15 minutes.

When did the Yanmar 3YM30 come out?

My boat has a Yanmar 3YM30, 2007. I have just finished a project replacing all of the wiring for the high current path from the alternator to the batteries, including the grounds.

What should the voltage of a marine battery be?

Once fully charged, marine batteries should be held at a considerably lower voltage to maintain their charge – typically 13.2 to 13.4 volts. Higher voltage levels will “gas” the battery and boil off electrolyte, again shortening battery life.

What are the different types of boat batteries?

The discussion of batteries can be divided into two major topics, battery construction and application, and charging.

What should the voltage be on a marine battery?

The voltage on a fully charged battery should be about 12.7-12.8 volts. If it’s higher, the charger is on. Batteries will usually fail to start an engine at 12 volts or less. This is dependent on the age of the battery. Is 12.3 volts a good battery?

How many volts does a deep cycle battery need?

Deep Cycle Batteries in a cycling application require a recharging voltage of 2.43 to 2.45 volts per cell. This is 14.6/14.7 volts for a 12 volt nominal installation and 29.2/29.4 volts in a 24 volt site.

What should the voltage be on a 12 volt battery?

People also ask, at what voltage is a 12 volt battery considered dead? This is called the “open-cell” or “resting” voltage of the battery. Resting fully charged 12-volt batteries are around 12.8-12.9 volts, and flat dead ones are at 12.0 volts, so 12.4 volts on a resting battery means it’s about 50% charged.
