    Easy to follow but why is battery ID picture upside down, and why didn't you snap a decent pic of the connector? Other than that, Well done.

Compare your new replacement part to the original part—you may need to transfer remaining components or remove adhesive backings from the new part before installing.

To reassemble your device, follow the above steps in reverse order.

Take your e-waste to an R2 or e-Stewards certified recycler.

the original took 2 lithium AA rechargeables. their update just creates ewaste

Kevin Weldon - crwdns2934203:0crwdne2934203:0

not lithium! Just standard Ni-MH AA's. I was pretty disappointed when I bought the second keyboard (the fist one was already pretty beaten up) only to discover that below the battery door there is just plastic and no battery! bastards... I used the keyboard from time to time as 2xAA charger (as most of the time it was connected to power) and I swapped those fully charged batteries with discharged ones from other devices that take 2xAAs aswell

Nellinka Fotky -

Do you have a part number for the replacement battery?

Ryker Bailey - crwdns2934203:0crwdne2934203:0

The part in the canadianbatteries.com link is not the correct part for this keyboard.

The correct PN is 533-000141, this has longer leads on the battery and the battery capacity is larger than the one linked. Aliexpress is the only place I have been able to locate a new one.

Ryker Bailey -

Kevin, exactly right. I have 2 of these, the original and this one. Whoever the brain trust was that came up with this cockamamy idea was a numbskull. The rechargeable batteries dont last forever, why make a product. you must basically throw away because of the imbecile design? Sheesh.

Daniel Roberts - crwdns2934203:0crwdne2934203:0

I was able to remove my battery and keep my K800 operating with USB power. I can wait for a battery from AliExpress.

How well does the Aliexpress battery work. I have been hesitant to purchase from them. thanks, John V.

John Vaillancourt -

What keyboard would have a similar feel to the K800? `

Nathan Cobb - crwdns2934203:0crwdne2934203:0

I wander if it's possible to replace some parts from old K800, the one powered by 2 AA batteries, and make a new one to run on AA batteries?

Any advice on how to deal with it? I have both old one, which is fatigued, but working, and a new one.

I've always chosen Logitech for quality and durability of their products. Here this company have clearly made a move to products that can't be repaired even for the most common cause of issue: change the battery. Wrong choice, really, completely in the reverse of where the world need to go.

As software engineer, I have always recommended Logitech products for my family, for office. Well, I'm done with Logitech.

This company is malfunctioning and now needs to be stopped.
