Dissembly Of Ryobi Battery?

I'm guessing this thing has a weak cell and Home Depot doesn't want to
hear about it.

I've removed 5 screws (one in each corner, and one in the tower-like
appendage), but something's still holding it together.

Anybody been here?

Under a sticker is a favorite place.
They often hold them together with double-sticky tape
that's stronger than what it's holding.

Last time I looked at Ryobi, they had a lifetime warranty
on batteries. Possibly, the lifetime of the battery, not
your lifetime. ;-(
I discussed it with a rep in the store. Asked him what they
were gonna do in 10 years when the replacement battery is unavailable.
I came away unsatisfied by his reassurances.

Just curious what you're gonna do when you get it apart?

Stated another way, if you don't need to put it back together,
you have more options for opening it. ;-)

Using a utility knife pry along all the visible cracks, and then just
use brute force to pry it open all the way.

suggests that there are some plastic clips on the long sides of the
body, and that you need to push the main contacts down and out of the
cover while you lift up. There are also wires to the "fuel gauge"
LED. Read the link; it has more details.

I recently took apart a DeWalt 12V NiCd pack of similar mechanical
construction. Once I got all the screws out, it took a little shaking
and wiggling to persuade the cover to slide off of the cell that's in
the "tower" part. The cell wasn't swelled or broken; it is just a
close fit. The main contacts were in their own piece of plastic which
easily came out of the tower.

I was going to try to verify that it had dead cell(s), but not many of
the inter-cell connectors were accessible. I didn't want to tear into
it too far, so I ended up putting it back together.

Various places online sell rebuild kits... often you get the cells
already assembled, and you swap the new cell set into your existing
plastic housing. I asked at a local Batteries Plus store about that
DeWalt battery and found out they offered a rebuild service (they put
new cells in my housing) that was pretty competitive in price with
buying the cell assembly online. I haven't had the pack rebuilt yet
so I don't know how well their rebuild service works.

Standard disclaimers apply; I don't get money or other considerations
from any companies mentioned.

IME, it's not likely that a method other than the screws is relied upon to
keep the case together, otherwise they would have just used more glue/etc
instead of the more expensive process of providing for and installing
screws.

Lately, I've been checking Youtube links** that show up when I search for
items I'm curious about.
There are a couple of videos that show how *to change the charger's mind*
about a pack that it may determine is bad.
I searched for Open Ryobi Battery, IIRC.. and spotted a description of: how
to make a charger charge...(? it was clearly a Ryobi charger but the brand
wasn't mentioned).

The procedure is to plug in the charger, insert the pack into the charger
(LEDs show fault), then rapidly cause interrupted AC power at the cord plug
by removing it from the receptacle and briefly reconnecting/contacting the
AC plug several times, followed by fully plugging the cord back in (LEDs
then indicate normal charging).

If this isn't a couple of random coincidences, then it seems to be a case of
the smart charger being out-smarted.

There was another reference to some Ryobi chargers being identical to some
Craftsman models, even though the 2 brands' packs are different voltages.

I can appreciate that lithium batteries have good power densities, but I'm
triying to avoid them when possible.
The newer pouch batteries (like putty wrapped in foil) are sometimes a
special size and can't be replaced with anything else within the same amount
of space.

I prefer NIMH and the common sizes of cells that can be easily located when
replacement is needed.

BTW.. a rapidly intermittent AC power source connection to many electrical
devices can cause damage, such as *telegraphing* the AC connection to
transformers. The back EMF collapsing meets newly acquired incoming AC
power.
Blown fuses, failed primary xfmr windings and breakdown of sensitive circuit
components can be a result of this type of rapidly repeatedly interrupted
interrupted AC power.

** Granted.. there are a lot of youtube videos that are worthless, and many
that are made so poorly, they're unwatchable.

Measure each cell's voltage in an effort to confirm my weak-cell
suspicion.

If one is way down, try charging it separately and then putting it back
into the array. If that fails, keep the remaining cells against the
day when another cell in another battery (I have three others) fails.

I'm kind of locked into Ryobi: two drills, a saber saw, a multi-function
tool, and three chargers.

I was quite disappointed with Home Depot's reaction because I showed
them another battery that was bought on the same day, been through the
same service, and works a-ok.

OTOH, the Home Depot guy said that a number on the batteries indicated
they were manufactured over five years ago. OTOOH, I have a hard time
believing that I've had these things that long... maybe 3
years...Maybe...

The reason I paid extra for Lithium batteries is that mine only see
intermittent use - months apart - and lithium does not spontaneously
discharge on the shelf.

If I were to do it over again, I would buy DeWalt.

Dissembly?

"Disassemble" means to take apart. "Dissemble" means to disguise or conceal,
especially one's motives.

So it looks as if either verb applies -- the battery is concealing the means
to take it apart!
 
An option would be to build a heavy duty battery pack to attach to your belt
and a cord going to the tool.
This would make the tool much lighter, less fatigue maybe (over head use
etc).

I've done this with dustbusters and other internal-battery-design devices.
There are inexpensive universal chargers capable of auto-sensing 4.8 to
10.6V or 12V to 16.8 NICD/NIMH packs.. I just bought one for less than $20
to take care of 14.4V packs.
The universal chargers get more expensive at 24V, and again over 40V.

I checked, and Word's spell check accepts "mi" (as in do re mi) as a
legitimate word. So me could be replaced with mi, further confounding things.

However, it might now be un-balanced -- making some tools
more "nose heavy".
But, yes, definitely Something to consider.

Thanks.

CANDIDATE FOR A PULLET SURPRISE

I have a spelling checker.
It came with my PC.
It plane lee marks four my revue
Miss steaks aye can knot sea.
Eye ran this poem threw it,
Your sure reel glad two no.
Its vary polished inn it's weigh.
My checker tolled me sew.

A checker is a bless sing,
It freeze yew lodes of thyme.
It helps me right awl stiles two reed,
And aides me when aye rime.
Each frays come posed up on my screen
Eye trussed too bee a joule.
The checker pours o'er every word
To cheque sum spelling rule.
Bee fore a veiling checkers
Hour spelling mite decline,

And if we're lacks oar have a laps,
We wood bee maid too wine.
Butt now bee cause my spelling
Is checked with such grate flare,
Their are know faults with in my cite,
Of nun eye am a wear.
Now spelling does knot phase me,
It does knot bring a tier.

My pay purrs awl due glad den
With wrapped words fare as hear.
To rite with care is quite a feet
Of witch won should bee proud,
And wee mussed dew the best wee can,
Sew flaws are knot aloud.

Sow ewe can sea why aye dew prays
Such soft wear four pea seas,
And why eye brake in two averse
Buy righting want too pleas.

I've never checked one of their lithium batteries, but with their nicads you
just remove the screws and then pry apart slowly so the piece of mica with
on bottom that has the sticky stuff on both sides comes off.

Ryobi seems to be pretty good about replacing batteries, even slightly
out of warranty. If you paid for the drill kit with a Visa, Discover, or
American Express card, they double the warranty, up to an extra
year, for factory warranties up to 3 years long with Visa or Discover,
up to 5 years long for American Express. Mastercard does this only
for warranties up to one year long, and they seem to be a lot worse
about providing reimbursement.
