Just when you thought everything related to fish finder batteries had been discussed already!

How do you charge your battery?

Constantly when not in use?

Before/after each trip?

Before/after each trip though I don't mind leaving it on charge when I forget to unplug it.

Have been forgetting to put it on charge lately and my new FF was set to not have a battery alarm, so now it seems to never get fully charged :(

Depends on the battery and charger:

For my SLA batteries I use chargers that are designed specifically to remain connected so they can periodically condition check the battery and keep it in premium order. While they're more expensive to purchase initially they've greatly extended the life of my batteries and ensure they're fully charged whenever I need them. Also negates the need to periodically charge SLA's (e.g. once a month) when not in use.

For my Lithium batteries I NEVER charge them without monitoring them i.e. if I go out or head to bed I stop charging. This means that once charged I always disconnect them.

Mine is SLA and I charge it after every trip and put it on the charger again before I head out. Works well.

Yeah, that's what I do normally, then last time I didn't recharge just before I went fishing, battery went to shit quite quickly, followed by the FF (see other thread).

I have a CTEK smart charger which I use on my jetski battery. I believe this has sorted my FF. It's now charging normally.

Moving on, I don't know whether to go back to what I was doing before...

OR

keep the SLA attached to the charger when not in use, charger is similar to this:

OR

buy another expensive CTEK charger and leave that attached when not in use.

It's an interesting problem: how expensive is an expensive charger?

I've opted for a CTek. Since going to it I've not had to replace a battery despite my cycling them extremely deep on the large sounders I use. Previous to this I used a good quality budget charger (roughly $35-$40) and was getting around 2 years out of a battery before performance dropped to the point it needed replacing as it couldn't last a full session on the water. Since I'm using 12Ah batteries at around $70 each the CTek charger has already more than paid for itself in savings on replacement batteries.

Using fuzzy logic I might even be able to argue my charger is now making me money because I'm not buying replacement batteries :lol:

Good post. Looks like I'll be buying another CTEK :y:
