Alternative to the 12v 45ah battery?

Heat definitely doesn't do batteries any favours. The best life I've had was where the battery is in the airflow - the worst was a Mitsubishi van where the battery was tucked in a corner under the seat - always hot. Moving PRIUS from the boot to under the bonnet possibly has increased the amount of heat it receives. But - I've got 2 years out of mine so far, which is more than the Mitsubishi van ever got from a battery.

 

In previous threads, I’ve mentioned several LN1-type batteries sold in the U.S. and in Japan with characteristics very similar to the original. As I wrote two weeks ago, though, I’m not aware that anyone has tried one and then posted here to report whether it worked.

 

The extreme temps do make a difference. Cut off everything - AC, lights, etc. when you are getting ready to cut off the car for a while. Cause otherwise, you could end up like me - my GPS screen went blank which then meant no backup camera and thus not able to put in Ready Mode. When this happens, I was able to give it a couple to a few minutes for it to heat up in winter from a freaky cold day ( I had accessory mode running to heat up interior of car) and the opposite just recently with triple digit heat index days.

Now from my research as a newbie. The Prius battery is a smaller 85 cold cranking amph hour battery and thus is basically a golf cart sized one. Due to the hybrid battery and alternator, it doesn't need to be big and powerful, which means that we have to be aware of this for when plugging in stuff to trunk and hooking directly to battery. The voltage level is low, so even with a medium to large inverter, if the item to be powered require 11.7 or higher voltage, then use a wireless app or controller to cut it on only after having run aka drive for a few minutes first, so the power is there. I just know hooking straight up to battery is a more continous flow vs fluctuating current like if plugged in front DC outlet.

So please chime in and correct me as needed and add any additional information that could be helpful to all of us. I'd like confirmation that I have been learning correctly thus far.


Questions:
If battery is replaced with a more powerful and larger AGM, how would that effect the current flow and all for the car and how effects current flow and power to power extra hooked up stuff?

If I made little slide out rubber pieces to fit between the battery terminals and the hooks of cables to an inverter, would those little rubber pieces stop the tiny tickle of energy lost from keeping inverter hooked up to terminals? It's a pita to hook and unhook it due to stuff in the car ATM, but I could simply pull out and slide in (well enough I guess ) the rubber slip/stop piece.

Why not replace AGm with small lithium battery?

Anyone know what the wattage or amph hour ends up being of the oem AGM battery? There's not a simple equation to figure out cold cranking to watt or amph hours.


Thanks and hope this helps.


iPhone ?

 

Are you asking in relation to your PRIUS v? If so, it would be better to ask on the PRIUS v FORUM - they'd be more familiar with your car.

 

Some of what you say or ask is just general Prius battery knowledge, but the Prius v and the Gen 4 Prius use different batteries, so I agree with @alanclarkeau that the Prius v forum would get you in touch with more people who know the things that are specific to the Prius v.

 

i just reread that whole thread. i can't believe no one has reported a non oem cost and installation yet.

 

I'm interested of Purchasing one... do you happen to have the contact info?

 

will not fit your gen 3 battery bracket, and may not be suitable for inside the cabin.

 

It would be Gen 2 I think?

 

yes, unless they have another car.

 

Excellent bit of kit, I have the 3.8 version. I revived a dead 12v disability scooter battery with mine. After the charger stopped and the LED indicated that the battery wouldn't hold a charge I let it rest and ran it again, same result so I thought I'd give it one more try before scrapping the battery and lo and behold, third time lucky, it passed the not holding charge LED and went on to fully charge the battery. It's now held a full charge for two months and is working fine.
