I've never gotten 19 yrs out of one but have gotten 12 out of each of the others I've owned.
Come to think of it the one in 'Frankie' is ten years old this month! Mine had a blue top and marine posts though  ......maybe that's the difference. |

I had an Optima Blue Top for about 19 years, including several times being run COMPLETELY dead. Based on my experience I'd sure say it was a good value, even at the premium price. I considered replacing it with another, but cash was tight at the time so I just went with a cheap starting battery. Also all of the internet experts I read were saying that Optima quality had taken a huge downturn (although their price hadn't). But take that for what it's worth...

Build a small hydraulic winch system!
There is plenty of room to mount a small hydraulic motor or power steering pump on the engine, especially if you aren't going to have power steering. Northern tool offers a clutched v-belt hydraulic pump. You could also drive a pump off the crank pulley up under the radiator, kinda like the crank starter. Install a small hydraulic winch behind the front bumper. Warn still makes 6k unit in the industrial line. MileMarker also has many choices. Perhaps a small tank and power steering cooler. The control system could be anything from an electric solenoid to a mechanical valve. Cable control valves are common also. You could have the business end in the engine compartment for short hoses, but mechanical control with a push/pull cable in the cabin space. As long as the engine is running you could be winching. You could drag yourself up anything pretty much.

Brennan, those are cool options, but mucho dinero. If I’m going to spend a pile of money, I’ll just go 12 volt, but for now I’ve decided not to decide, instead I’m just going to sit tight.

12v makes all the issues goes away.
Even running a separate 12v alternator and battery just for the winch would be easy. I winch a lot off a small light group 51 battery with a 100 amp gm alternator.

I also have run a separate 12 volt battery & alternator on a 6 volt 1948 Chevy pickup. I used that system for the off road lights that I used. It worked well. I would guess that it would also work well for a winch.
As far as getting a hybrid 6/12 volt battery, It would be hard to keep all the cells in such a battery fully charged without over charging half of them. It can be done using two 6 volt batteries. But once you go to two batteries, it would be best to have one 6 volt & one 12 volt. I do not go places that I will have to winch a long distance. If I need a winch, I carry a couple of hand winches that I use for short pulls. |

Smfulle not to throw a wrench at you on all this but have you considered an manual winch for the few times you will need it? I have one I picked up at a farm auction rated to hoist 3000 lbs vertical. I havent used it yet but it has a hand crank on it and I modified a socket to fit my electric drill which will drive the winch, throw a snatch block and and the thing is pretty fast. I bought mine at an auction so I only paid $15 for it but you can get some small hand winches for under $100.

My personal vote is to convert the entire Jeep to 12V. The benefits significantly outweigh all other possibilities. Truthfully a 12V conversion is pretty cheap and can be completed in a Saturday of work.
-can find parts anywhere anytime (and cheaper) -everyone can jumpstart you and vise versa -winches are instantly compatible -engine cranks faster -brighter lights -cell phone charging capability -additional accessories like tire pumps are compatible

I would simply mount a 12V AGM deep draw battery on the PS firewall. I would not hook it to the main 6V system. It would have a 120>12V marine charger mounted and would be dedicated to the winch and as emergency starting. This is similar to the set up I use on my boat to split the starting battery bank from the 24V trolling motor bank. However, on the boat I use a charger that charges both the 12v bank and the 24V bank.

another vote for 12v conversion. Also allows you to run a high torque starter which i like to use to start in gear when i stall on a tough obstacle...save the clutch

My 6 volt starter will start me in low gear going uphill on an obstacle. |

2 6v batteries. Series/parallel switch. Keep your 6v system and have 12v avail. Wiring no big deal.
