Battery charging ?

I have a Napa Marine/RV battery and I noticed my new Schumaker charger has 3-4 settings

Standard, AGM, Gel..Which setting do I use when charging?

Thanks!

Standard unless it is an AGM ( glass mat) or gel. The battery will identify as such. Most likely a lead acid standard battery.

Do most of you keep your battery charger plugged in at all times? If you have your boat stored off site, how do you handle keeping batteries charged

If you have a good quality charger it shouldn’t be a problem leaving them hooked up all the time. I hardly ever take mine off charge.

most folks keep them on trickle chargers full time when the boats are in storage from what I seen in the past ...

I know this is late but currently mine is off site until next month. I just take it home the night before and let it trickle charge over night. Go fish and bring home. Let trickle charge and once full I disconnect the accessories and leave only main battery connected

I would keep battery inside your garage at home if possiable . Keep on trickle charge as much as you can . Freezing weather is hard on battery if it goes down . Very important to keep water level up and only use distilled water.

Mine is on site. I use 10 amp per bank chargers. I don’t think a trickle will give you full charge.

Can you add water ? Standard . If sealed it will be labeled on battery .

If you leave a charger on the batteries full time, you should have a good quality "smart charger", otherwise you run the risk of overcharging your batteries. Maintenance (trickle) chargers should also be "smart chargers", such as Battery Tender chargers.

Use the setting for the type of battery you have. It should tell you on the battery if it's a AGM or gel (and be "sealed"), whereas a "standard" (wet cell) battery will usually have fill caps.

If you're still not sure ... give us the info from the top of the battery and we can determine which charge setting is needed.

They say you shouldn't charge lithium batteries below freezing. I've accidently left my chargers hooked up though. Most good lithiums have cold and hot shut off circuits.
