The old cement floor story goes back to when battery cells were GLASS, and there was a possibility of breakage and acid loss. No need to worry with modern batteries.
Seaweed- you can charge each battery separately with a 12 volt charger. Your on-board charger simply sends 12 volts to each battery- no difference.
Anyone who has stored a partially discharged battery since last fall will have reduced their battery life, period. Fully charged batteries in good condition normally take very little if any charge over the winter.
CCB- lurking gets too frustrating... almost choked when I read about pike not biting because they lose their teeth in winter...
{You said it} takes very little if any charge over the winter so why will it reduce the battery life? The only time that will happen is when you will leave the battery outside in the freezing cold. The crank amp will be down when not charged but will fully charge in the spring because it takes no voltage when setting in a basement.
icescool wrote:A battery that can't recharge when not in use is a useless battery. Why? Because when you leave a battery still and its voltage can't come back to 12.7 volts then it has had it days. I’m not talking about crank amperage. I’ve seen battery perform everyday and I have a good sense about it. I’ve taken courses on this and I have asked questions about it. They say the same thing as me. If your battery can't go back to 12.7 volts then there is no point in charging it. If you charge it one hour after fishing the memory will not be the same because you did not drain the voltage. The memory will go to the point that you started and when you finished. A battery has to be drained and then recharged so your battery will have good memory of a full charge. If you charge it half way then you will have a battery that will give you half the time of use.
Icescool, Thanks for your detailed reply. I really need to question the course you took, check your notes please. A lead acid battery can not develop memory problems! period.
Nicads are the ones that develop a memory if not properly cycled. Total discharge and recharge will remove the memory.
Lead acid batteries suffer from different problems. To fully discharge any lead acid battery, whether a car battery or a deep cycle battery will ruin the battery quickly. The problem is "Sulfation". A discharged lead acid battery forms lead sulfate which settles in the bottom of the case causing voltage drop and plate problems, and eventually a battery that will no longer hold a charge.
The best way to encourage long life in your deep cycle lead acid battery is to limit discharge to 20% of charge and to charge it frequently and as soon as possible after use.
Not everyone can limit their discharge to 20%, to do so would mean many spare batteries, but that is the ideal amount to prolong life.
I maintain hundreds of lead acid batteries monthly for backup/standby power systems. I too have taken battery manufacture's courses.
AC DELCO THAT WERE I HAVE TAKEN MY COURSE AT ALGONQUIN
Sulfate & plate problems happen when you use 80 % of the battery and then lay it up without charging it . Tell me if your battery will let you use it to that point . The only time i was told that will happen is when the battery is do for replacement .
I got to agree with Troutslyer on this one.
I have worked on auto floor scrubbers which use deep cycle lead acid batteries(marine) and that is what we have been told by the battery manufecturers,suppliers and service centers.you do not wait for these batteries to drain 100%(as a matter of fact some automatic chargers do not charge them if they are totaly drained)charge them after every use ASAP and lead acids do NOT have memory problem.you CAN place them on the concrete floor for winter storage.check water level is above the plates,clean them with a damp cloth then wipe with a dry one and charge them every month or two and then give them a good over night or 24 hour trickle charge before reinstalling them in the spring.

You are right about that fact, but Sulfation occurs at all levels of discharge, more for 80% than 50% for sure. I think I said the same thing you are saying now.
My question to you was, What in your "AC Delco" course made you think lead acid batteries could develope memory?
Or are they/you calling deminished power due to sulfation "the memory"?
I didn't want to fight about it, but I didn't want people to be lead astray on the age old "NiCad Memory" thing.

Right on the button calling diminished power due to sulfation "the memory. But telling others the way we see it will not be the same as you and me, so maybe I should not do it this way and say it like it is.

fight about what we are talking about a battery and i injoy talking about it iam glad i had this talk with you .

Glad we agree pal!
The memory thing is temporary in nicads and can be reversed or fixed.
The diminished power thing in lead acid is permanent and it's goodbye battery.

Ive had my batteries a long time and they seem to die faster now and will never show a full charge. I have had this one battery for 4 years nows is that why? it has a 3 year warranty. I also have a 3 year old one that will not fully charge aswell which has a 30 month warranty. Do these companies know that there products fail shortly after the warranty run out, I am sure they do. Can someone please give me some names of the batteries i should replace these 2 with when it is time.

Frustrating eh? it's almost like planned obsolesance!
I think only a few manufactures produce the many different named batteries. I found by switching to Gel-Cell type batteries, the Sulfation is much less and I can still get full charges after 5 years. I do recharge after every use, and trickle charge over winter.
Smitty wrote:Can I just charge them now or in the spring?
Any advice?
thanks
Smitty
Smitty, I hope we answered your question! I would charge them now, and after every use, and a few times between!
I have a "connection" at this place (not trying to push this place on anyone btw, because my connection does not = any kind of discount ). So I am going to try and find out more about this process. I have a couple of old CT batteries that are starting to show their age. But, if the price is right, and I can get a few more years out of 'em ... well, the math speaks for itself.
Triple M, I use a Trojan from Total Battery for my electric motor and it has been great. I recharge after every use and trickle charge once a month through the winter. Went a little oversize so I had some extra reserve amps and it has serviced well.
I'm no expert on batteries but don't you have to be careful charging a batt. in the house because of the hydrogen gas? that is created ,,,,, big boom /fire ??

I do believe you should charge them in a ventilated space
