Thanks! Wish I had known wayyyy back when.....I just know they SUCK even as a starting battery in my Jeep. Have to change under warranty way too many times.

You are not alone, many have been down that road. Only experience can teach us sometimes.

VA-Apraisr,

Optima have about 40% less space for active plate material. About the only thing they are good at is vibration resistance. In all other cases, a more conventional design may be a better choice.


I guess I'm an Optima customer with a rare bird: I have an Optima battery that I occasionally use for backup. It's at least 15 years old and still charges well and holds a charge.

It's a Yellow Top Optima battery that is in Group 31 size (but only ~90 amp hours due to it's cylindrical cells) and was manufactured by the original European company. About 6 months after it was released, the U.S. military contracted with Optima to buy all production output of that model. I got one at an auto parts store just before that happened ... and it was $$$ even way back then. What a battery it's been!!!

By the way, does whoever now owns the Optima brand still offer Yellow Top batteries? Their AGM Yellow Top batteries were/are supposed to be for deep cycle use.

Update: Ok, my brother installed the BattleBorn batteries (2) 100ahs and upgraded chargers (house and alternator) as well as a 3000wt inverter. We wired microwave directly to inverter so I don’t have to use generator. Well, currently on Cape Lookout, NC for a 12-day fishing trip. What a FANTASTIC UPGRADE!! Voltage system starts at 13.6 and I’ve been here 2 days and have left the TV on for 12 hours each day, used microwave, lights and refrigerator and volts are now at 13.1.....haven’t had to run engine or generator at all. House lights are LED’s and are so much brighter. If you do any boondocking, this setup is worth every penny!! And, no it’s wasn’t cheap $2650 but a big investment for my type of off the grid camping. And I don’t watch TV for 12 hours....just testing the capacity of this system ??

I’ll follow up as the trip continues.

Tnx VA-, that sounds great. Don't forget to include a good fishing story. Even if you have to make one up. [emoticon]

I fly RC model planes powered by Lithium Polymer batteries. They require special chargers that "balance charge" individual cells. These small battery packs are "limited life items" that need to be kept charged to a minimum of 3.7 volts per cell or they become damaged. During use, individual cell internal resistance gradually rises, causing a reduction in capacity and performance and swelling of cell packets ("puffing") requiring replacement. It is also necessary that model type battery packs need to be discharged down to a "storage" charge of around 3.8 volts per cell when not in use, or their useful life is shortened. I'm wondering how RV lipoly batteries are kept in good condition by "BMS" devices and need for monitoring and replacement.

My point is they have lower capacity per unit of volume / foot print.

They are (or were) good batteries.

They sent a 60amp Lithium battery charger for generator/shore power and a Sterling power battery to battery DC charger for chassis battery/alternator charging while driving. It’s also a surge protector for overload surge back feed to alternator. Both designed for use with their battery. Put my trust in their knowledge and expertise and hoping for the best. So far so good ??. And the fishing sucks but beautiful weather on the island. Heavier winds coming which should help fishing ??

The Battleborn Sterling DC-DC on their site is 24-12, so how can you use that in a MH? Do you have a 24v engine battery?

What is the scenario for a surge from House to Engine side?

BTW, their 60 amp "Li battery charger" is just a PD converter set to single voltage (not three stage) at 14.6 ish (seen different values for 14.x on that) and the advice seems to be to disconnect it from the Li after the Li is charged up--ie. Do not float at 14.x for very long.

Or is that wrong and yours does drop to 13.6ish for floating?

Suggest confirm output of that PD converter is not over the Battleborn limit of ISTR 14.6. ISTR some of those "Li PDs" are at 14.8

Hope you can clarify how all that actually works, as this is new tech that many of us are trying to understand. Thanks.

Ok, the BB site does have a 12-12 version on page 2 of their "shop".

Sterling has some explanation of all this for newer vehicles with REGEN systems where the alternator can get to higher voltages than the House batts can withstand. Very interesting if you have a newer C.
