They are slightly too big. Regardless of how slight, these WILL NOT WORK in my old yellow and black Eveready lantern. These batteries COULD BE fabulous, wonderful and other superlatives, but how would you know if THEY DON'T FIT and therefore DO NOT WORK!!! ### ⭐⭐⭐⭐⭐ initial charge 6.75 volts! *by B***Y on January 13, 2025* the 1st order 1 battery charged but showed 0volts at the poles. Amazon quickly reshipped the order with free return label. The new pair both charged to 6.75 volts compared to nickel-cad 6.45 volts. So far very pleased. ### ⭐⭐⭐ Slightly larger than standard 6V cell *by B***R on December 28, 2024* I bought the two-pack because I had two lantern lights, but it only fit in one of them for me. As you can see from the picture, it is slightly larger than a standard 6V battery cell and as such did not fit in one of my floating lantern lights. I measured about 1.5-2 mm wider all around. ## Frequently Bought Together - NERMAK 6 Volt 6Ah Lithium Ion Lantern Battery 2 Pack, 2000 Cycles Rechargeable LiFePO4 Battery for 4R25 Lantern(Spring S2 Terminals) - Interstate Batteries 6V 5AH Sealed Lead Acid (SLA) Battery - Spring Terminals (SLA0916) - Wildgame Innovations Outdoor Hunting Power Deer Feeder Battery Charger Edrenaline Solar Panel --- ## 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.pl/products/678052461-nermak-6-volt-6ah-lithium-ion-lantern-battery-2-pack](https://www.desertcart.pl/products/678052461-nermak-6-volt-6ah-lithium-ion-lantern-battery-2-pack) --- *Product available on Desertcart Poland* *Store origin: PL* *Last updated: 2026-05-07*
