Charger/discharger who’s better?

Prolong.

 

IF.....you still have the original HV battery in your 16 year old Prius, your money will be MUCH better spent saving for a new car.
Seriously.

 

It appears you got a Thanksgiving treat from a member I have on ignore.

Seems like an appropriate action so you can celebrate a holiday and not have some extreme negative comments to mull over.

As long as you are willing to undertake the maintenance yourself, a used Prius can be a valuable mode of transportation .

Happy Thanksgiving .

 

For one, Maxx Volt only allows for charging and not discharging .

If you want to get the most out of a pack that is seasoned, you'll need to discharge it to break the "memory" of the cells.

The Prolong harness makes that task easy.

I had a similar decision to make back in 2017 and went with Prolong and these were some of the reasons .

 

Exactly, why spend $700, no challenge, no sense of accomplishment so DIY less than $100.

Because when you are talking about trying to "rejuvenate" a 16 year old battery it is TRUE.

And doing that IS undoubtedly wasting money because it does not WORK in any meaningful sense.
AND it can be dangerous for someone with no skill or experience.......which some of your earlier posts tends to indicate is true.

NOT a good idea. I quit.

 

Don't confuse me with facts, my mind is already made up.
If it doesn't conform to what you think is true, you don't want to hear it.
Good policy.

 

A new OEM battery is ~$2000 if you install it yourself. The Prolong charger/recharger is ~$600 (last I heard). Does it make sense to spend 1/3 of the price of a new battery for this sort of bandaid? Balancing a battery using one of these devices may give it a year or two more, but a new battery is probably good for 15 years. The former only makes economic sense if you don't expect to keep the car for very long.

 

Installing the prolong harness and maintaining the battery starting in 2017 has allowed the battery in our old 2010 to continue operation.

So that's more than two years.

If done consistently following the directions, the battery life can be extended.

 

You are talking about your vehicle. More than a few suckers have spent $700 or more to only end up buying a new HV battery.

Consider that a Prolong uses Meanwell components.

 

We also used the Prolong equipment to rebuild batteries.

It has many uses for one purpose.

I got my investment back and then some.

 

Well......you don't KNOW that because you have no way of knowing what the life would have been had you done nothing.
But you probably won't understand that either.

 

I read this as a derogatory comment, is it meant as such? Honest question. Among a Dutch electronics forum*, Meanwell is seen as an excellent brand, delivering a quality that is consistant at a pricepoint a little above the poorly designed China crap.
It doesn't have the quality of e.g. my Delta Electronics PS that supplies me with spare components after 30 (!!!) years free of charge, but Meanwell is adviced to all without much reservation.

PS: I don't use or have any Meanwell PS.

* many on that forum have intimate knowledge or even design SMPS, so I trust their judgement.

 

Well you are wrong! The $100 Maintenance gear uses Meanwell power supplies, same as Prolong.

Imagine spending $100 and getting your investment back? How many folks spend $700 for Prolong and don't get their investment back, that they could have spent on a new HV battery.
