Watched the video a few times before attempting!! Bingo!!! Works like a charm ### ⭐ Bad instructions *by A***. on March 22, 2025* My 1 star is not for the battery or seller, they would've probably had 5 stars. No issue with the battery as it did power up my tablet. I was refunded for the battery right away. The 1 star is for the video instructions. The issue is the included video instructions shows opening the tablet from the display side. This was wrong for my tablet and doing so destroyed it. The tool tore through the very short flex cable connecting the display to the main board. The display and main board were connected together with two flex cables. Unlike the video showed when opened. My tablet is the Samsung Galaxy Tab 3 8.0 SM-T310 and needed to be opened from bottom side apparently. My tablet is now worthless as the toch screen is not connected and not repairable. Maybe some of the tablets need to be opened like the video. Mine was opposite. Picture 1 is after opening it per the video (display side). Picture 2 shows the destroyed cable (display side). Picture 3 show destroyed cable on main board side. Picture 4 shows how it looked after opening from bottom side which matches how video showed the battery. Be careful. Not happy. Now that I'm out a tablet, I feel someone owes me a replacement or an assist with replacing the tablet. ### ⭐⭐⭐ Not easy. *by E***A on March 30, 2016* I broke the tool that came with the kit. Finally used a credit card instead. Then I damaged the credit card. I don't have the patience. ## Frequently Bought Together - NP99sp NewPower99 Battery Kit for Samsung Galaxy Tab 3 8.0 SM-T310, SM-T311, SM-T315 with Tools, Video Instructions, Long Life Battery - Kaisiking 5mm / 10mm x 50M Double Sided Adhesive Tape LCD Touch Screen Tape Phone Repair Tape with 1 Tweezers for Cell Phone, iPad, Tablets, Laptops, Camera, LCD Screen - B7000 Jewelry Glue Clear for Rhinestone, Cridoz 3.7 fl oz Craft Adhesive Glue with Precision Tip Multi Function Fabric Glue for Metal Stone Graduation Photo Charms Nail Art Bead Jewelry Wood Glass --- ## Why Shop on Desertcart? - 🛒 **Trusted by 1.3+ Million Shoppers** — Serving international shoppers since 2016 - 🌍 **Shop Globally** — Access 737+ million products across 21 categories - 💰 **No Hidden Fees** — All customs, duties, and taxes included in the price - 🔄 **15-Day Free Returns** — Hassle-free returns (30 days for PRO members) - 🔒 **Secure Payments** — Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** — Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.gr/products/13333086-np99sp-newpower99-battery-kit-for-samsung-galaxy-tab-3-8](https://www.desertcart.gr/products/13333086-np99sp-newpower99-battery-kit-for-samsung-galaxy-tab-3-8) --- *Product available on Desertcart Greece* *Store origin: GR* *Last updated: 2026-08-06*
