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.

Check here

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.
There are lithium batteries made to take the place of 2 AA batteries
side by side in cameras and radios etc that use 2 AA
batteries.(RCR-V3) (CR2) They are available rechargeable. AAs are be a
bit of a trick because of the 3.7 volt standard. But I HAVE seen them.
Also the camera standard RCR123a is available in rechargeable Lithium.
Also rechargeable lithium ion 9 volts (can't find the number)

I HAVE A CHARGER FOR THE LITHIUM 123A

That´s 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 weren´t 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.
