An alkaline AA is 1.5v, while lithiums are 1.8. If you have a device that requires 6 AA batteries, it is designed to run on 9 volts. However 6 lithium AA batteries deliver 10.8 volts, which can damage the item. Using one of these "dummy batteries", will cut that by 1.8 volts, which brings youback to a perfect 9 volts. ### ⭐⭐⭐⭐⭐ 5.0 out of 5 stars Perfect For Replacing Two AA Alkalines With a LiFePO *by A***R on Reviewed in the United States on June 7, 2018* Exactly what I needed to make an old two AA penlight more versatile. I used a single rechargeable LiFePO 3.2V battery with this, and a replacement LED bulb to resurrect an ancient medical penlight. Works great! I plan to do the same with anything else that takes an even number of AA batteries...replace half with placeholders, and the other half with rechargeable LiFePOs. ### ⭐⭐⭐⭐ 4.0 out of 5 stars Enables 1 Li-ion instead of 3 metal hydride *by B***D on Reviewed in the United States on February 21, 2019* Enables use of Li-ion batteries instead of 3 metal-hydride or alkaline batteries. 3.7 volts versus 3.6 or 4.5 volts.Just install one Lithium Ion battery and two of these in those cylindrical triple battery holders,either AA or AAA type and wallah, you have a rechargeable battery flashlight! Make sure length of replacementcells is the same as what you are replacing. --- ## 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.sk/products/51456321-4-pack-aa-battery-placeholder-cylinder-aa-size-hot-dummy](https://www.desertcart.sk/products/51456321-4-pack-aa-battery-placeholder-cylinder-aa-size-hot-dummy) --- *Product available on Desertcart Slovakia* *Store origin: SK* *Last updated: 2026-05-30*
