Where can I get a Polaroid Pogo battery?

Your Polaroid PoGo CZA-10011B printer's firmware sounds like it might have a problem. The red light could be an indication that the firmware is not properly interacting with the battery, which is preventing it from functioning properly, if it remains on even after the battery has been fully charged.
Although firmware upgrades are not always accessible for all devices, they can help resolve bugs and enhance the functionality of the device. If the device's firmware version V2.4.1 cannot be downloaded from the manufacturer's website, updates may no longer be available for the product. One option is to try getting in touch with Polaroid customer service and asking about a firmware upgrade or if there is another way to fix the issue. Additionally, you might look for user forums or groups for your particular printer model to ask for assistance or advice from other users who may have gone through a similar situation.
Another option would be to try a different battery from a different supplier, sometimes even though the battery seems to be compatible it might not be the correct one for the device. It's important to note that if the firmware is not available to download and the device is not working properly, it might be time to consider a new printer.

If you a reasonably handy you could disassemble the battery pack and replace the cells with new NiCad or NiMH units. They are not complicated and you should find lots of sites on the net that will supply the cells. Alternatively if the unit has a DC socket you should find the voltage and current printed beside it. Try fitting a suitable power pack.

Hi, I found some wires at amazon, click here and take a look:

Its cheaper to get another one as it sounds to me like there is a component problem on the circuit board which is part of the charging circuitry that charges the battery when power is applied.

Assuming it is the PoGo instant mobile printer ... (and not a digital camera - category that you posted your question) ... slide the battery door cover downwards to open.
See the illustration in the 5th page of the manual (under installing and charging the battery): http://office.manualsonline.com/manuals/mfg/polaroid/cza10011.html

first of all make sure that the pogo it turned off insert the paper from the packet with the blue peice on the bottom with the barcode facing down. and the paper facing shiny side up and logo face down. when you turn the pogo on the blue paper will feed through first then the printer is all setup and aligned ready to print via bluetooth or via USB cable. hope this helps

Install the battery (see above steps).
Connect the AC adapter to the printer and the power source.
Notes:
Before using the printer on battery power, fully charge the battery for
2.5 hours.
You can print photos while plugged into the power source.
