What explains the electric toothbrushes that don't have
replaceable batteries? You have to toss a $60-$120
device just because a $5 battery has failed.
Using the battery to enforce product obscelence
is standard practice in the industry.
Mindlessly superficial. The reality is that its a lot easier to
allow battery replacement with some items than with others.
I totally disagree.
Your problem.
No reason they can't make a new standard - Lithium Polymer battery
pack about the size of a SD card that just snaps into a device.
Wrong again. There's a real problem with Lithium anything
and separate chargers. Thats why you dont see the standard
AA and AAA cells in Lithium anything format either.
Sorry but you are missinformed.
Nope.

These are AA and AAA lithium batteries.
Those arent the RECHARGEABLE batterys being discussed.
Pity they wont fit in an ipod. And arent practical with electric
toothbrushes either.
The point is that consumer AA an AAA lithium batteries are available.
Nope, not the RECHARGEABLE batterys being discussed.
Thatīs the point, not if these batteries can be fitted to an IPOD or a Thootbrush.
Wrong, see the top of the quoting.
You said that Lithium batteries werenīt available in standard sizes
Yes, and it should have been obvious that what was being discussed was RECHARGEABLE batterys.
and I proved you that you were wrong.
No you didnt.
Also, there are smaller lithium batteries available for watches and calculators.
Those arent RECHARGEABLE either.
Even there are user replaceable lithium batteries for cellphones and laptops,
Yes, I said that.
which further demonstrates the concept that rechargeable lithium
batteries can, and in fact are produced, in a variety of formats.
Pity they arent practical with external chargers because of the
real problem with RECHARGEABLE lithium batterys in that format.
There's a reason they go bang if not RECHARGED properly.
Thatīs why the manufacturer puts the charging circuit *inside*
the cellphone or the laptop, to avoid charging problems.
Yes, and why you dont see rechargeable lithium AA and AAA
batterys, because some fool will inevitably put them in an inappropriate
charger and they will go bang very spectacularly indeed.
Also, the IPOD battery is a lithium rechargeable one, so a
lithium battery charging circuit can be made as small as needed.
Yes, but we were discussing why the battery
cant be a STANDARD AA OR AAA FORMAT.
Put simply: if the manufacturer *wants* to design a product with batteries
that can be replaced or recharged the manufacturer *can* do it.
Not with a standard battery format they cant, because that
would inevitably see some put them on inappropriate chargers
that would produce spectacular results when they did that.
The technollogy exists, and in fact itīs in use actually.
No it isnt with STANDARD BATTERY FORMATS.
Even there are different chemistries available, so if an applicattion works
best with a NiMh battery, or a NiCad one, that battery can be used.
Pity about the problem with putting a lithium battery in a charger
thats designed to charge NiMh and NiCad standard format betterys.
