I'm needind ti re-stock my ball machine. I used pressureless balls for around 18-20 months, and they still bounce fine. The felt has started to come off on them is all.

Am I better off getting more pressureless balls, or buy new pressured balls and get one of the ball "chargers" that claim to retain the bounce in pressured balls?

any experience on how long normal balls remain "like new" using the chargers?

I bought the Tennis Ball Saver a couple years ago for about $10. It works great for keeping new balls new. When I keep my balls in it, I have to replace the balls because they go bald, not because they go flat. They also claim to rejuvenate old balls, but I have not found it to do that very well.

Thats almost 2 years... probably good idea to change them... you dont have to but we just recycle double core practice into the machine every 6 months... the machine balls goto classrooms I guess? Ball savers? No need... you cant get about 100 of them... he must have about 300+ balls... ;) muaha turn that crap all day long... normal balls... 2 dollar a can... dont die that easy... DC balls are cool too... dont need savers... Pressureless are not that good IMO we use old 6 months DC in there... its better but pressureless... not bad :) never tried the charge... if you have letme know how it goes thanks :)

late to the party sorry,
i bought a couple of Gamma ball pressurizers online, actually 4
IMO whether these work or not, the balls do better in the pressure cans then out in your bag
what i woudl like to know is if their is a pressure chamber like this for more then 3 balls at a time, like for practise balls, i usually have 120+

I assume you have a lot of balls for your ball machine, not just a few. So while the Tennis Ball Saver canister works in my experience, it only holds 3 at a time, so it won't work in your case for a lot of balls.

You're better off buying new pressureless balls in this case.

Normal balls won't remain "like new" in the Tennis Ball Saver, but they do hold up the pressure good enough to keep the balls playable for a long time, until you want to replace them because they're too bald.

I don't know why they claim it can repressurize dead balls. I agree, it does do a good job of keeping new balls new. I usually rotate the bald tennis balls to my ball hopper for serves.

i look at it this way, and i can be wrong on this
the air in the ball gets hit out by playing when new, craeting small holes in the rubber, thoes same holes the ball repressuriser uses to push air bakc into them, the problem is that because the holes have been used to push air out and then bakc in again now become larger so the bounce will be lost quicker the second time you play with them, but it will be at the origional pressure when you start hitting with them again
i did try this out on some old balls, they did return to their original bounce, but like i mentioned, it did loose the bounce fast, after about a set or a few games of play
if you have the chance, buy one and see, the balls you just opened can be used for 1 more day before going into the hopper, they would be better of in the repressurizer then in your bag waiting for the next time you play with them and you save SOME money

But I don't like the 3 ball models, and the large capacity ones are too expensive. For more information on some better options check out this blog (not a store)

In my opinion NONE of the readily available ball inexpensive pressurizers work. If the seals were able to actually hold pressure similar to that in in unopened can for any significant amount of time they would, but they don't.

I've tried the "Tennis Ball Saver" above and when you screw it down (with 3 ball inside) to create pressure, for all practical purposes it appears to work. But when unscrewing it back open, if you get a audible sound as it's opened - this is NOT evidence of pressure being held, but exactly the opposite! The pressure created has long since leaked out and the process of opening it created a (temporary) vacuum.

As the previous poster alluded, the only pressurizers that actually work are big $$$$. These should really have a gauge to check/verify and re-pressurize if need, here's one for $200+....

EDIT: Link may be censored - do a image search for "tennis ball charger" for a pic if it doesn't show.

Another option is building your own. There was a very good thread on this a while back. A search turned up these interesting links but I'm not sure I found the one I was thinking of...

I had one of the Gamma 3 ball pressurizers and I threw it away. The thing was terrible. If you're looking to actually revive dead balls, you are supposed to leave them in the pressurizer for a month. So really there's no point in using them to store balls unless you only play once a month, otherwise the effects will be negligible.

The other thing that I have noticed is that if you store them in one of those devices for only a short period of time, the top ball will be dead and the bottom ball will be overpresurized.

Right and wrong. The ones that hold 3 balls work only for awhile. But don't spend big bucks.
My "tennis ball" pressurizer cost me only $30.00 and holds 30 balls. No it was not designed for tennis balls, but who cares as long as it works.
