Should i buy a brand new hybrid battery for my 2012 Toyota Prius C with 116,000 miles?

It's sad that PriusC was built with less battery power than a regular Prius... Prius C battery packs die sooner than regular Prius because of this. If I were you I'd upgrade to projectlithium.com

 

The only opportunity to significantly improve performance of your Prius C is with a project lithium pack.

 

Yes... Has performed flawlessly for more than a year: Dr. Prius Packs Less Than A Year Away? | PriusChat

 

Better voltage difference than a NiMH and has also run cooler as well... The real value is in mountain climbing and EV mode where performance is doubled when battery drains down to three bars there's still plenty of power and never drops to two or one bar. Also pack recharges up to full bars much faster.

 

Did Toyota tell you why? It's odd they won't take your old battery as a core.

 

I agree it doesn't make sense Toyota won't take back the core.

After a couple tries I managed to keep my original battery in my '01 going for about two years using modules purchased on Ebay, but I probably just got lucky. Went with an after market rebuilt pack after that, which ended up costing me more in the long run than if I just went with the new battery from Toyota.

My daughter's C might eventually need a new battery, so would be interested how well the project lithium packs work.

 

It was a prototype I was doing Winter testing on and no money involved in the exchange...

 

I want to get a nexpower battery. Does anyone know of anyone could install it for me
Around Chattanooga or Atlanta that is experienced at changing the main battery?
Also would like to change smaller battery at the sametime.. I am willing to pay 250.

 

Can you share some data to back up that statement? I have a Prius-C, and would like to get prepared if this is true.

 

The data is simply the number of battery modules used in Prius C battery pack is roughly a third less than all other battery packs used in Toyota hybrids...

Another data point is that It typically takes 10 to 18 years for all other Toyota hybrids to have a bad battery pack... But for years now Prius C with battery packs less than ten years old are showing up here on PriusChat as already worn out.

Good news is there's no waiting list or outrageous Toyota stealership prices if you buy a Nexcell pack, so you not only save on MPG compared to OEM packs, but you save on price to replace your battery pack. Also if you replace your pack before it goes bad you can recover some of your costs for a Nexcell by selling it, whereas Toyota will force you to put a $1300 on your old battery pack until you return it to them.

First see if following symptoms are present then decide to buy new battery.

• Lackluster or harsh acceleration.
• Abnormally low MPG.
• High Delta SOC. (39+ to 80%)
• Fast charging & fast discharging
• Frequent ICE on & off cycle.
• Min. & Max. cell voltage difference: (For new battery-Max. 0.16V, for good used Max. 0.28V and for bad 1.2V to 3.5V).
• Abnormal noise from engine.
• Abnormal Win & Wout. (Std. for Prius Gen 3 is +/- 20K)
• Low discharge rate between engine on/off cycle remains below 2 minutes. But For new or good battery discharge rate remains 4.5 to 5 minutes.
• High min & max voltage fluctuation, For new battery 15 to 16 volt & for bad battery 14.5 to 18 volts.

 

Don't monkey things that is not broken. The prius c had lower torque motor and engine since it is new. Nothing wrong about it. Lithium battery is not as reliable as NiMh with Lanthanum electrode. Lithium also have fire hazard unlike NiMh, especially it is unknown chinese battery, not Panasonic.

 

pack core trade is a deal breaker for me. The whole used battery industry has turned into a complete rip off in my mind. The industry was formed for the purpose of recycling used packs. All it does now is to recirculate old ailing packs back into the used pack markets.
YMMV
