I give it 2 1/2 stars...

I.M. Anonymous @ 6/26/2000 6:05:22 PM #
I got my FullCharge on Friday the 23rd. Initially I was excited, but after checking it out over the weekend, I feel let down. Here's why:
1) slow charger: it takes 10-12 hours for a full charge - for $35 I expect a fast (1-3 hour) charger;
2) cheap battery pack contruction: the pack is held together with what seems like hot glue and the label. After noticing this, I'm paranoid I'll break it...
3) poor fit: when removing the battery pack it feels like it's going to rip the springs out of the Palm battery compartment! The instructions say not to remove and reinsert too much: guess why...?
4) overall quality: maybe my standards are too high, but my overall impression is more towards "garage-product" than "pro-engineering"
5) price/performance: for $35 I can get 2 sets of high-capacity (650-700 mAh) NiMH cells and a fast charger and still have money left over. Plus I'd always have a full spare set of cells to swap out.
6) long-term performance: I'm hoping that the charger pins will still mate securely to the battery pack sockets after a few dozen insertions/removals - there's a 90-day warrantee so if they loosen up I'll be asking for a swap.

I've gone on longer than I intended to, but reading the "rah-rah-hype" review here made we want to add my two cents. (I mean, come ON - battery life with FullCharge's 550 mAh cells is the same as 1000+ alkalines??? - give us a break! We want a critical review, not an infomercial!!)

Don't get me wrong, I don't think FullCharge is a bad product, but I wish I'd waited to see how the rechargeable solutions from http://www.palminfocenter.com/view_Story.asp?ID=649">Solutions for Individuals (assuming it isn't vapourware) or http://www.revolvedesign.com>Revolve Design (are they shipping yet?) compare" CLASS=NEWS TARGET=_NEW>http://www.palminfocenter.com/view_Story.asp?ID=649">Solutions for Individuals (assuming it isn't vapourware) or http://www.revolvedesign.com>Revolve Design (are they shipping yet?) compare.

Why are you pulling the Full Charge battery module out in the first place?

Wow - those links got interpreted in a weird way!
What I tried to close with is this:

Dear Anonymous,

Wow - Our feedback on FullCharge has been overwhelmingly positive; much like the review posted here.

That being said, we are concerned that every one of our customers be completely satisfied with their purchase. Since FullCharge for Palm has not lived up to your expectations, I encourage you to contact me personally and we will provide you with a complete refund, including shipping. Email: JHarvey@eXtendComputer.com or Telephone 248-960-0772

I hope you will accept this refund offer, so you may pursue one of the other solutions you've mentioned here (which may better suite your needs).

For the benefit of any reader who wants a detailed response, I would like to address each of your comments.

1) Slow charge time...
A) As indicated on our web site, FullCharge is a slower style charger (10 hours for a full recharge, 12 hours if the battery is completely dead). Fast charging (1 to 3 hours) requires additional electronics be built into the battery or the Palm itself, in order to properly sense the battery's condition and to guarantee safe charging. Cell phones, laptop computers and even some wall plug chargers include these electronics from the beginning design of the product. Unfortunately Palm never incorporated these electronics into the III and VII series (because they never intended them to be rechargeable). We investigated including the electronics into the FullCharge battery but the limited space (volume) within the Palm III battery compartment prevented this. As it turns out, the slow charging is better for the batteries themselves, and so the number of useful charge/discharge cycles is greater. Finally, fast charging (1 hour) causes the batteries to heat up which may not be desireable while holding a Palm III or VII.

2) Cheap battery pack construction...
&
3) Poor Fit...
A) These are directly related; and not that we have anything against hot melt glue, but it is not used in the FullCharge battery. Actually, the battery assembly is bonded with an epoxy.

The starting point here is that the Palm III and VII were designed to hold two AAA batteries. And since Palm wanted the size of the device to be samll, they didn't waste any space in the battery compartment. So when we decided we wanted to make the Palm rechargeable, and we didn't want to have to remove the battery in order to charge it, it was necessary to design a method of connecting and disconnecting directly to the batteries. Of course a plastic molded, fully enclosed battery assembly with an integral connector (like a cell phone or camcorder) would have been an ideal solution. But there just wasn't enough space within the battery compartment to contain such an enclosure (not without having a bulge protrude out the back of the Palm). So the batteries had to be bonded to each other, with the connector sockets attached directly to the battery cells and even then, it is still a tight fit (just as we state in the documentation). But, if what you want is to put in the battery, install the new cover and have a rechargeable Palm, then that is really all you need. Honestly, again, it is not designed to be taken out and installed over and over again (and actually, this defeats the purpose). Finally, realize that the battery contacts are attached to the battery itself. These contacts are recessed below the battery cover on the FullCharge battery. This is a small thing but it eliminates any concern about them shorting out (in a purse with coins, in a pocket with a money clip, etc).

4) Overall Quality..."garage product"...
A) As noted at the beginning of this response, we do want our customers to be happy with their FullCharge purchase. If it fails to meet your expectations, by all means contact me to arrange a refund. As for the "garage product" observation, I hope the information provided in this response gives you some sense of the level of thought and design which went into making FullCharge install and work as seamlessly as it does.

5) Price/Performance...
A) For $35 most Palm users won't have to remove or replace the batteries in their Palm III or VII again (see review above). Just plug it in when it's convenient, and it'll be ready when needed. Comparing it to 4 seperate rechargeable batteries that need to be removed and recharged is hardly the same.

6) Long-term Performance...
A) FullCharge has accumulated tens of thousands of hours of use without any pin/socket interface problems. Obviously we don't anticipate any problems with the pin/socket interface between the charge plug and the battery if the the system is used properly. Like most higher quality electronic connectors, the FullCharge pins and sockets are also gold plated for long life performance.

The final comment about how 550mAH NiMH cells could possibly get similar life to 1000+ mAH alkaline batteries can be understood by looking beyond the basic mAH rating. In fact, we highly under-rate the capacity of our batteries so as not to mislead (even accidently) the actual performance. All battery capacities are measured at a given discharge rate, and unfortunately many different discharge rates are used (they are not standardized). And, as it turns out, NiMH battery chemistry is less affected by the discharge rate than alkaline battery chemistry. So a TRG Pro accessing a flash card (high discharge rate) will actaully cause a significant reduction of alkaline battery capacity (provides much less than the 1000 mAH rating) while the NiMH will perform closer to the 550 mAH rating we have given FullCharge). Also, the Palm handheld computers give the low battery warning and then shutdown at a voltage which is higher than the end of discharge voltage for alkaline batteries. Basically, when your Palm says your alkaline batteries are dead, they still have some life left and your Palm can't use it.

For the readers who have persisted to read all of this, I hope you have a better understanding of what FullCharge for Palm is, and what to expect from it. If, like us, you don't want to have to keep swaping batteries in and out of your Palm III and VII, then FullCharge is a carefully designed solution which will meet your needs.

My first question is why would you want to take it out of the Palm? Once it is in, you simply hook up, charge, unhook and go.
The time it took to build up the full charge was not a problem to me since the Palm can be operated at the same time.
I am sorry that you didn't get to feel the same sense of joy that I did when I got my charger. I have bragged to everyone I can get to stand still long enough to look.
I am looking forward to a resurgence of joy as soon as I can order the car adapter. Being paid biweekly has its downfalls!

Wow! Great reply/discussion. When are you going to come out with the Handspring version??

I have been using the product for a month now and I am
quite pleased with it. I have the AC adapter set up at
work since that is where my Palm III gets used the most,
and I haven't had a problem with the equipment
yet. It has gone through many plug/unplug sequences
with no degradation on any of the supplied items. I
rate it highly.
