Battery

Four Batterys need replacing again would like people's opinion which to go for agm or traction thanks all

Horses for courses, or what is best for you, your boat, and that way you operate.

 

Both are lead acid batteries so both will be subject to sulphation if not kept very well charged.

 

Traction batteries are likely to be open cell whereas AGM are sealed.

 

AGMs may have a better performance when subject to high discharges and high charges.

 

Traction probably need regular equalisation and voltages higher than an alternator can produce, and may well need regular topping up.

 

For me, and it is personal, I would rate the ability and ease of comparing the state of charge of individual cells on open cell batteries way above any convenience from AGMs. But that depends upon how easy it is to access the battery tops.

As above, how do you use the boat? CC'er liveaboard year round with no shore power? CC'er liveaboard who spends the winter in a marina with shore power? Holiday boat used in summer only? Liveaboard in a marina with shore power? Plenty of different use cases.
