I put the CTEK on the battery and set it to recondition mode and left it overnight. By the morning it reported it was in the "float charge" mode....
If it were solely for my PP, I would give some serious consideration to just making my own jump battery with 3 20A Sony 18650 batteries. If you...
All too well, in two PPs so far. I'm going to see if I can "revive" the battery with the CTEK to see if it's a degraded battery issue, or if the...
You'll still have to maintain the charge in your jump unit. Even lithium batteries self-discharge. If the unit even has a milliamp parasitic drain...
When this happened with my 2018 the dealer put in an order for a new battery under warranty and Toyota USA actually interfered to cancel the order...
I don't have a 12V battery charger. I have no 12V charger currently, but I ordered a CTEK to see how it goes. Maybe the batteries are sitting a...
Just got back from driving 98 miles today. Grabbed the Fluke right after I parked and measured the 12V battery at 12.23V. This is almost exactly...
The external charger is key. I suspect my low voltage has to do with the car dropping the 12V system voltage from the DC-to-DC converter down to...
Nothing plugged in right now.
From my 2018. Taken when the car was 2 months old. [IMG] From my 2021 just a few minutes ago. [IMG] If I'm not mistaken, that corresponds to...
This hasn't been my experience with 2 PPs now. Both batteries show around ~12.0V after surface charge is bled off. In my 2018 I drove it 80+ miles...
I wonder if it really matters? The car just needs a 12V source of power momentarily. Do the battery's physical dimensions really matter as long as...
I hadn't checked my PP's 12V battery until this thread got me curious. Right now it's sitting at 12.05V, which is low enough to encourage...
There's something going on with the Gen 4 and 12V battery maintenance. My 2018 battery was always around 11.8V. The dealership wanted to replace...
They were telling me that back in 2018, so it may not necessarily be related to Covid. In fact, the dealership had put one on order for me and...
Unfortunate, too. I'd love to be able to use 16AWG to wire my house with 2,400W circuits. So easy to work with compared to 12 AWG.
To use a month's worth of power in one day I would have to charge 184 Prius Primes or 15 extended range Model 3s from dead to full in one day.
