Hello, new to this forum and doing my first DIY Hybrid Battery Reconditioning project on a '06 Gen 2 Prius. Found a lot of corrosion around the nuts and bus bars when taking the pack apart and have read mixed reviews on whether or not using products like Noalox (anti-corrosion compound) or dialectical grease on the connections when I reassemble would be helpful or not? I soaked the nuts and bus bars in a vinegar bath which did a great job at cleaning them up. Still trying to make a final decision on the Noalox though so any insight or suggestions would be much appreciated. Thanks.
Are the nuts and really clean in vinegar only I never thot so I tumble em or replace . I use a spray didn't even think of noalox I have plenty here it's not been used for years now as slum changed 25 yrs ago or so. It conducts so I guess worth a try . It's a past so flying sir thru case stuff could pile up on it possibly
Hello, I have a related question. Battery technology is evolving all the time. I'm sure that we'll have the option to upgrade to newer and better batteries, and I'm sure that some companies are developing batteries with the form factor suitable for a Prius. Let me know if this is true.
Yeah they pop.up on market place every other day . Issue is so far all of em make a out 8 to 16bminths and fail . The Panasonic has reliably made 8 to 10 years pretty steadily for the 20 years of the manufacturing cycle so you know kinda tricky giving up that reliability. For some newfangled nonsense that won't be here tomorrow. And the cost is always very close to the original you're saving very lil
Sodium Ion battery for Prius $1900 Toyota hybrid battery upgrade pack– NexPower Energy This company had previous new tech batteries that failed early but they back them by selling you this newer battery at a deep discount. It remains to be seen if it's viable, it hasn't been tested for very long. It has more power and it's 30% lighter. I don't see why a better battery can't be developed, the NIMH type in the Prius has been surpassed for a long time in the hobby sector. And the Chinese have a new EV battery that charges a 200 mile capacity in just 10 minutes
Must be something to this because I've seen an Asian company offering a sodium upgrade too so will win over all been tried . It's kind of hysterical they're having same issues on volt forum
I also use a rock tumbler to clean hardware... As for the anti-corrosion electrical grease it's a huge mess next time you have to take the pack apart and corrosion begins through the seals where threaded terminal comes out so its very difficult to treat the areas that most need the grease. And maybe if you were putting a brand new pack that you won't see for a decade or longer, it'd be wise, but anything old you'll be working on again in coming years, don't do it! Also you can get 10% off if you use my link in signature below for new nuts, busbars and voltage sensing harness... Make sure to look inside battery ECU for corrosion too... But how thorough you want to be has more to do with the pack's lifespan on a spectrum of all newly replaced modules with brand new on one end, to a pack that's mostly made up of used replaced modules. Most people on here won't bother once they've replace one or two bad modules with a matching used on because the reliability goes town if you don't have enough modules to choose from.
I find that a brass rotary brush on a Dremel does the least damage. It takes off corrosion without gouging the metal coating too much.
