  • Remove the old battery: Gently slide or lift the old battery out of the bay, taking care not to pinch any cables. Set the spent battery aside in a safe place for proper disposal or recycling.
  • Install the new DENAQ battery: Align the connector with the bay and slide the new 8-cell battery into place until it clicks securely into position. Ensure that the battery is seated flat and the latches engage properly to prevent movement during transit.

Great value glossy photo paper
Size: 5"X7"
This photo paper works really well with my inkjet printer using dye ink. The colors come out bright and sharp, and it dries quickly without smudging or smearing. The glossy finish gives the photos a clean, professional look, and the 180gsm weight makes it feel sturdy without jamming or being too thick for my printer. So far, I’ve used it for family photos, thank you cards, and a few school projects. The results have been consistent, and I like that there’s no watermark on the back so I can write notes or dates if needed. The pack comes with 100 sheets, which makes it a great value for how well it performs. If you need affordable, good quality glossy paper for home printing, this is a dependable choice that makes projects look polished.

Exceptional Quality and Value!
Size: 8.5"X11"
I recently purchased the Koala Glossy Inkjet Photo Paper and I must say, I'm thoroughly impressed. The quality of this photo paper is outstanding, providing crisp, vibrant prints every time. The 8.5x11 inch size is perfect for printing standard photos and the 48lb weight gives the paper a sturdy, high-quality feel. I've used it to print everything from family photos to professional presentations, and the results have been consistently excellent. One of the things I appreciate most about this product is the quantity. With 100 sheets per pack, it offers great value for the price. I also found the paper to be well-packaged, ensuring it arrived in perfect condition. In terms of compatibility, I've had no issues using this paper with my inkjet printer. The ink dries quickly, preventing smudges, and the glossy finish really makes the colors pop. Overall, the Koala Glossy Inkjet Photo Paper has exceeded my expectations. I would highly recommend it to anyone in need of high-quality photo paper. It truly deserves a 5-star rating!

Satisfied with quality used with Epson ET-8550. Last ship no box > slightly damaged corners.
Size: 11"X17"
I have had good results with the Epson ET-8550. So far I've used about 400 pages printing at the max quality settings. Now whether it is the ink or the ink in conjunction with the paper, but the prints once dry don't immediately run when splashed with water. Now I'll spray UV clear on most prints but I've been pleased with that aspect. Decent weight, good surface. The only kicker is that earlier orders arrived in boxes and those were well protected. My last order was in a just the poly bag, no box. If Koala cost cut the box, that's disappointing because many pages had their corners damaged despite delicate handle during shipping. (Har har) If you find you a corner that has been affected in shipping, what I do is feed the good end first and minimize the risk of an uneven corner causing jams. BT recommended
