Was charging and replacing bad ones then I added them up! all 12 volt.
3 for cars and Pickup
4 AGM for wheelers and boat ( they don't last like the lead acid ) about 2 years kept charged
4 Lead Acid for boat and trailer
1 New Lithium for electric trolling motor

Ad them up and any maintenance ideas for longer life.

My outside batteries are trickle charged once a month, the rest are stored in the garage and trickle charged a couple of times every winter. Seen to many battery fires to leave a trickle charger on all the time.

6

13. No batteries for the boat because it needs a total repower, which I probably won't get to in this lifetime. Only one is outside on trickle. It's in a spare car. The trucks outside get used enough to negate trickling.

I got all the materials to set up a trickle system in the shop, for the batteries in storage that don't get used annually. That only amounts to a few, like the motorcycle, electric trolling motor, etc.

6 for vehicles, camper, rec-cabin water pump, 6 AGM 4 wheelers/snow machines.

None on trickle charge- I top most of them out monthly if removed/kept in heated garage and not in vehicles. One 4wheeler AGM outside in 4-wheeler - brought in for top-up at monthly intervals. 2 snowmachine AGM kept in machines outside- one requires top up every couple weeks or goes dead- must have a light drain on it somewhere.

3 for our vehicles, one for each
1 for tractor
4 for boat (3 for trolling motor)
1 for trolling motor for the big Jon boat
1 for Zero turn mower
1 for ATV
1 small lithium for the depth finder in Jon boat

Been researching Lithium batteries and outboards, seems they will ruin boat alternators, they will not regulate or spike voltage when they shut down.

Best to run them to the house side, and use conventional lead acid or AGM directly to outboard. Using a 12-volt to 12-volt charger to, charge Lithium.

Bass Pro Tracker boat guy told me they would not warranty their outboards if a boat comes in with a lithium battery, and they also sell Lithium marine batteries, too many boats coming in with bad alternators. Also, asked if they were told that when they bought the lithium battery he said no???? So remove the lithium battery before you bring it in!

Not a lot of information out there on this.

Too many. But since you asked I had to start counting. 4 spares on the floor in the barn that were getting old and were safety changed out but we keep around for issues.

Does 6 volt count? grins.

14 in Texas. 11 in Alaska.

Its always time to change a battery somewhere.

And even though everything gets worse in quality we still are running Walmart batteries happily. 5 year are harder to find but just mostly seem to last. Had one on a diesel tractor go 8 years and I actually decided to replace it for safety so the wife didn't have to while I was gone. Nothing fancy. Just lead acid as far as I can recall.

After some counting I came up with 13 batteries.
Everything that is stored for the winter, boat, motorcycles, RV, yard tractor, ATV's, get the batteries pulled and brought into the garage. I don't trickle charge any of them except the motorcycles and those with NOCO charger.

I just put new batteries in the 2003 Ram 3500. $500+ worth.

The originals from the factory were going bad..... can't complain about 20/21 years of use I guess.

Couple weeks ago at the rec cabin, had to do a work around after it was parked in the lot for 5 days in cold weather..



Fired right up down there yesterday with the new ones in.

I now have a new 6' extension cord in the truck as well. It was a near thing getting the engine heater plugged in above without it!

I came up with 19 before getting into spares/backups. Plus one 48 volt in the forklift.

I use a receptacle timer like those used for engine block heaters. Trickle charger timers are given just a couple hours per day to charge. Works like a charm.
