Lithium Battery Jump Box?

[Stalactically Gupid]

I've carried around a NOCO lithium Jump Box for about 5 years in my Jeep. No Issues. I thought I read somewhere that if the 12v Battery was dead, the Hybrid NiMH and electric motor would start the ICE and charge the 12V. I cannot find it now and am wondering if anyone read or thought the same? TIA

I've had a number of Toyota hybrids over the years and have hung out on their message boards. What I've gleaned about the hybrid system is that the 12v battery brings the computers online. There are multiple computers, like 7, that need to be booted up. Once they're online, the big traction battery is brought online and takes over. The traction battery starts the ICE and basically runs the car from then on out. Caveat: I haven't done any research to verify this understanding. But it is an accurate summary of what is the common understanding out there.

The Hybrid battery is the primary means of starting the engine via the electric motor, the 12V battery and starter are backup if the hybrid side fails.

Please read the manual at page 622. You cannot start the system if the 12V battery is discharged.

Please read my post, never said it would!

So I was curious about this too, whether the vehicle can be jump started, how and what kind of jump starter etc. What I read and surmised is if the 12v battery (located in rear left side of interior vehicle) it CAN be jumpstarted (via front right side of engine bay). Read manual for specifics. I believe any jump starter is fine as long as lines reach the two locations indicated in manual. A NOCO should work I think. I was planning to buy one myself.

If you need to charge your battery (like trickle charge) there are specific parameters to follow for this as well. Read the manual.

The 12v battery starts the hybrid. The 12v battery is your autozone type battery (although Im unsure if you can buy the LC’s model—- might be very specific).

The hybrid battery—- well, if it goes out Im sure its a pretty penny. Curious how much. And Im pretty sure I wont be replacing that one myself.

And if you ever need to tow your LC, make sure all 4 wheels are off the ground!

The 12v battery is not anymore specific than other foreign cars. It must have a vent tube, and physically fit in the space so the hold down cage will hold it down........ The Optima DH6 is a direct replacement and has 800 CCA.

I did not see anything specific in the manual concerning trickle charging and mine has been on a trickle charger for a week or so. I replaced the OEM battery due to it going flat 4-5 times in a short amount of time. The Optima is also draining at a slow rate. I haven't had time to chase what circuit is causing the drain. In the manual it states this is normal, but if I can isolate which circuit is the culprit and shut that circuit off when it sits for long periods of time...... winner

Jeep Wrangler 4Xe hybrid battery periodically recharges the 12V battery to compensate for drain. This helps in a long term storage situation without a trickle charger in use.

Does the LC work the same way?

Did I read someplace a Toyota hybrid vehicle, if stored, should be run a bit every three months? However, I prefer a pulse/de-sulphation charger/maintainer.

I can verify the LC Hybrid battery will not charge the 12v battery when in the "off" position!

This is what I found on charging the battery, what I considered trickle charging. Has some good info and precautions.

"In the manual it states this is normal", meaning the drain you are measuring is normal? How long are we talking about until the battery goes dead? Would you be comfortable with using a low-current pulse charger/maintainer? Do not lead-acid batteries tend to sulphate when idle of long periods of time?

I put an Optima AGM battery in and use a C-Tek charger/maintainer with no issues.

Note: AGM batteries will charge on a lead/acid battery charger EXCEPT when they drop below a certain voltage level then they seem like they won't take a charge. The solution is to trick the charger into thinking it's ok by hooking a second battery to the discharged battery vis jumper cables. After the charger starts charging for a few minutes you can disconnect the jumper cables/2nd battery and it'll continue to fully charge.

Pro tip: Cordless tool batteries that won't take a charge can be tricked in the same way. Couple of heavy gage jumper wires from a fully charged battery to the dead battery (pos to pos and Neg to Neg) let it sit for 10-30 min depending on how discharged the dead battery is. Then disconnect the jumpers and put on the charger and magically it'll charge....... well most of the time.

I read that as don't exceed a 5 amp charge rate.

Yes, have done as you mentioned, to put a slight jump charge on a battery, so the "smart"(really?) charger will "know" to do its job.
