The kit includes all necessary components—copper and zinc plates, light-emitting diodes, and electric wires—making it an engaging educational tool for demonstrating basic principles of electricity and energy conversion. ## Description Fruit Battery Light Diode Science Kit Orange Potato Lemon Battery Physics Teaching Experiment ## Features - Instruction: 1. Firstly , take 4 Lemons(other fruits like apple, orange, potato also OK). 2. Push 2 metal plates (one copper, one zinc) into each of them, connect copper plate of a lemon to zinc plate of another lemon with wires. 3. Then, connect wire from copper plate of first lemon to long terminal(+) of LED (light emitting diode). 4. Also connect wire from zinc plate of last lemon to short terminal(-) of LED. You will find that the LED grows! - Package Included: 4 x Copper Plates 4 x Zinc Plates 3 x Light Emitting Diodes 5 x Electric Wires ## Images ![Fruit Battery Light Diode Science Kit Orange Potato Lemon Battery Physics Teaching Experiment - Image 1](https://m.media-amazon.com/images/I/618ylu0e76L.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ potato projects are hard. Good clips, good metal sheets. LEDs ok. *by P***L on January 31, 2023* This kit: the metal sheets in this kit are thin, but they generated power better than other kits I tried. Also the alligator clips are better than the non clip wires in other kits.Potato battery notesFirst off, if your kid is going to do a potato battery science project know that this is harder than it looks. The LED lights typically require 3 volts and about 20 mA to light them up. sometimes you will get lucky with fewer milliamps, but most require 20 mA. This requires more potatoes and more wires than you might expect. Obviously, results may vary, but don't expect this to work with 1 or 2 potatoes. It took about 12 potatoes (4 in series, 3 in parallel) for my kid's project. Expect it to take at least 4 potatoes. Most of these kits don't have enough wires to connect all the needed potatoes (if you use 12 potatoes as we did). I ordered two different kits, and then later 3 more of a third kit type before we finally succeeded.Also, the larger the surface area of the zinc/copper, the more power output you will get. The rectangular metal pieces seemed to have better electrical properties than the spike-shaped ones. I think they must have increased surface area.Powering a small siren/noise maker or a clock (included in some kits) uses much less power than the LED light. A small non-LED Christmas light takes about 100 mA for full brightness.Warning: The clocks in the kits are very delicate and the wires break very easily.Wires with alligator clips are better than wires without clips.One of the kits we used came with a single LEDS that flashes multiple colors. each color using a different amount of current (mA). This was pretty cool. It required about 6 to 20 mA to light up. I used my multimeter with a store-bought battery to determine how much current (mA) each load (LED light, fan, clock) used.Pro tip: boiling a potato for 8 minutes increases the power output (credit goes to Israeli Researchers)Also: You cannot charge a phone or light a large bulb from a battery. Those are hoax videos going around the internet. ### ⭐⭐⭐⭐⭐ Very easy to use, everything you need is included. *by H***D on May 26, 2022* Very happy with this kit, I bought 2 to help my son with his 5th grade project. I think a few of the bulbs were not working, but there are a few in the kit, so all worked out OK. ### ⭐ Flimsy, broken, didn’t work *by M***D on June 17, 2023* I bought this kit to do an energy experiment with my class.There were no directions with the actual kit. I had to search them on Amazon in order to find how to connect everything. I followed all of the directions that were printed on Amazon. The experiment did not work. The LED bulb did not light up. I kept trying again and again with all of the different pieces double checking, that I had them all connected correctly, and nothing worked. Additionally, as I was on the clipping, all of the pieces to put them back in the bag one of the alligator clamps, completely disintegrated, and fell apart. I am assuming that the poor manner that this item was constructed in, is why I did not work. I do not recommend ordering. This is a waste of time and money. ## Frequently Bought Together - Fruit Battery Light Diode Science Kit Orange Potato Lemon Battery Physics Teaching Experiment - EUDAX Fruit Battery Science Experiment Kit with Electronic Clock and RGB LED for DIY Home Teaching Toy, School Science Project, Education Subject - AstroAI Digital Multimeter Tester 2000 Counts with DC AC Voltmeter and Ohm Volt Amp Meter; Measures Voltage, Current, Resistance, Continuity and Diode, Blue --- ## 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.us/products/65228016-fruit-battery-light-diode-science-kit-orange-potato-lemon-battery](https://www.desertcart.us/products/65228016-fruit-battery-light-diode-science-kit-orange-potato-lemon-battery) --- *Product available on Desertcart United States of America* *Store origin: US* *Last updated: 2026-04-22*
