Designed for longevity, it boasts an impressive cycle life of up to 300 cycles and a decade-long float life, making it ideal for various applications in sensitive environments. ## Description A 2 volt 2.5 Ah pure lead sealed lead acid battery used in general applications such as emergency lighting UPS systems electronic equipment etc. ## Features - Power density - Per unit weight, the power provided by pure lead-tin products offers the greatest high-rate power density for your energy dollar. CYCLON's greater volumetric power allows engineers to consider more energy-supporting features. - Cycle life - Compared to competitive lead products (offering up to 200 full cycles), pure lead-tin batteries provide 50% to 200% greater full cycle capability. CYCLON product will deliver up to 300 cycles (100% DOD, C/5). - Float life - Conventional sealed-lead batteries vary greatly in specified standby life: from three to six years at 20oC, C/20. CYCLON Single Cells, however, offer a ten-year design life at 25oC, C/5, to 80% of rated capacity. - High stable voltage delivery - The high stable voltage delivery of a pure lead-tin battery results from its low internal resistance. The flat discharge voltage profile of our batteries, similar to Nickel Cadmium. - Safety - Since CYCLON Single Cells and Monoblocs emit minimal to no gassing under normal charging conditions they are safe for installation in offices, aircraft cabins, hospitals or any other environment occupied by human beings. ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B0002ILK86 | | Amperage | 2.5 Amps | | Antenna Location | Bicycle | | Battery Capacity | 2.5 Amp Hours | | Battery Cell Type | Lead Acid | | Battery capacity | 2.5 Amp Hours | | Battery cell composition | Lead Acid | | Brand | Enersys | | Brand Name | Enersys | | Item Dimensions | 34 x 34 x 68 millimetres | | Item Weight | 0.4 Pounds | | Manufacturer | Enersys | | Model Number | 0810-0004 | | Number of Batteries | 1 Product Specific batteries required. | | Number of batteries | 1 Product Specific batteries required. | | Recommended uses for product | Bicycle | | Reusability | Rechargeable | | UPC | 635241000016 | | Unit Count | 1.0 count | | Unit count | 1.0 count | | Voltage | 2.00 | ## Product Details - **Number of batteries:** 1 Product Specific batteries required. - **Brand:** Enersys - **Battery cell composition:** Lead Acid - **Battery capacity:** 2.5 Amp Hours - **Recommended uses for product:** Bicycle ## Images ![Enersys - Cyclon battery Enersys 0810-0004 (D cell) 2V 2.5Ah F4.8 - Image 1](https://m.media-amazon.com/images/I/61RQ0zsVVDL.jpg) ## Questions & Answers **Q: what would be the price for amount to 800 units? thank you** A: On a quantity of 800 pcs the price is $8.50 each plus shipping.

If you buy two of these batteries from us, the shipping should automatically be combined appropriately. As of this writing, 9/2/2015, the shipping for two would be $8.93 for shipping to the inner 48 states **Q: What is the shelf life for these batteries?** A: While a reliable answer to this question should come from the supplier or the manufacturer I can assure you that I have two of these batteries in an operating rechargeable flashlight since 1983 and two others in another flashlight since 2014 (bought new from Amazon) and they are all functioning splendidly holding their charges fully for months on end and accepting full charges with no signs of weakening. **Q: I want to use these in a waterproofed D battery holder - the kind with the springs. Has anyone done this? If so what was your method?** A: I haven't but with the spade terminals on top you could get connectors from like Radio Shack and remove the spring and contact plate from your battery holder and solder the new wires to them with the crimp connectors. Multiple battery's could be a room issue allowing for some space between batteries for the new terminals and something non conductive or electrical tape to insulate the terminals between batteries while connecting in series or what ever it needs. I think the bottoms are plastic so might not be an issue but good measure. Shouldn't be hard if there is space and later replacement would be an easy unplug and replace. ## Frequently Bought Together - Enersys (Hawker) Cyclon 0810-0004 D-Cell 2 Volt/2.5 Amp Hour Sealed Lead Acid Battery - Zeglavi 12V 1300mA Sealed Lead Acid (SLA) Battery Charger with Short Circuit Protection - ML7-12 - 12 VOLT 7.2 AH SLA BATTERY - Mighty Max Battery brand product, black --- ## 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.co.uk/products/93940645-enersys-cyclon-battery-enersys-0810-0004-d-cell-2v-2](https://www.desertcart.co.uk/products/93940645-enersys-cyclon-battery-enersys-0810-0004-d-cell-2v-2) --- *Product available on Desertcart United Kingdom* *Store origin: GB* *Last updated: 2026-06-16*
