Each is listed at 8Ah (8,000mAh), giving you a second battery to keep available while the other is in use or charging. The packs are designed as replacements for compatible DeWalt 20V MAX batteries. Their 20-volt rating and stated 8Ah capacity make this a practical format for shoppers looking for a paired replacement set rather than a single battery. - Type: Rechargeable lithium-ion battery pack - Voltage: 20 volts - Listed capacity: 8Ah (8,000mAh) - Quantity: 2 batteries - Warranty: 2 years The manufacturer describes built-in protection for conditions including overcharging, over-discharge, short circuits, excess current, overheating, and reverse charging. A PC+ABS housing is also specified. ## Everyday compatibility These batteries are intended for 20V MAX slide-style tools using the matching battery interface. Listed compatible tool battery interfaces include DCB200, DCB201, DCB203, DCB204, DCB205, DCB208, and DCB2010. The manufacturer also names the DCB118, DCB112, and DCB115 slide-style chargers, along with most original 20V MAX slide-style chargers. A two-pack can suit a home workshop where tools are used across several tasks: keep one pack on a drill or other compatible tool while the second is ready for a changeover. If you are comparing a single replacement with a paired set, this option provides two batteries for jobs that benefit from having a spare on hand. Buyer feedback on fit and charging is positive in some accounts, with customers reporting that the batteries fit compatible tools and chargers and charge quickly. Feedback on battery life and capacity is mixed, however: some customers describe long use between charges, while others question whether the packs deliver the listed 8Ah capacity. Those reports are useful context when comparing replacement options. ## Tips for day-to-day use Charge each battery fully before its first use, as the manufacturer recommends. For long-term storage, fully charge the pack beforehand, the manufacturer notes that improper storage may shorten its service life. Using the original charger is also recommended for the intended charging experience. For a job involving several tools, keep the second battery charged and ready so you can switch packs when needed. Check that the tool and charger use the compatible 20V MAX slide-style interface before fitting a replacement. On a 4A charger, the manufacturer estimates about 2 hours for a full charge. ## Before you decide **Which tools are these batteries designed for?** They are designed for compatible 20V MAX slide-style tools, including models that use the listed DCB200, DCB201, DCB203, DCB204, DCB205, DCB208, or DCB2010 battery interface. **Which chargers are named as compatible?** The manufacturer lists the DCB118, DCB112, and DCB115, as well as most original 20V MAX slide-style chargers. **How should I prepare the batteries for storage?** Fully charge the pack before storing it for a long period. The manufacturer recommends this to help preserve battery life. ## Should you buy it? This VelgoNyx set is suited to owners of compatible 20V MAX slide-style tools who want two rechargeable replacement batteries in one purchase. Its key practical appeal is having a spare available for tool changes or charging rotation, with a listed 8Ah capacity and a 2-year warranty. Match the battery interface to your tool and charger, then follow the recommended charging and storage steps for everyday workshop use. ## Images ![VelgoNyx 8Ah 20V MAX Replacement Batteries, 2-Pack, Lithium-Ion — 1](https://www.ofertitastop.com/i/AV0IZ328kOlENqQTMWtSfDFneL85FAr6rqHvLxv2EW8yM9hsys07r6ujICQMwAUg4Be-RwHQyx6cV_UMCGD7aDdQz06mscn-q9ZAtz_ZB4zOsQkuthhGIHa6FQ.jpg) ![VelgoNyx 8Ah 20V MAX Replacement Batteries, 2-Pack, Lithium-Ion — 2](https://www.ofertitastop.com/i/gBO8CDtGEbjaFdtsE8lB4hdHNWRgsxO5ZW2ZRR_hfmpivV6h045S2VUVbTSHj78bSqpsGHOqN8K1c51-WHd3M3_isjQ0UCHXyIT8cNlkChPe8x-vZidwVyDllQ.jpg) ![VelgoNyx 8Ah 20V MAX Replacement Batteries, 2-Pack, Lithium-Ion — 3](https://www.ofertitastop.com/i/3EYKsiPQRUCrltUJCps_rPlAbJHZ3c26YjvK_zQuj72aMlLekGZJZqjSlBfEBDgdNPJOSVv8L3HCp_lbbP_LNnrcNa8I6Gf74s5AZab0o-0WMvFTpRc0MM-WBg.jpg) ![VelgoNyx 8Ah 20V MAX Replacement Batteries, 2-Pack, Lithium-Ion — 4](https://www.ofertitastop.com/i/NV5gsrnbkmpminw0jNI6ktgMfHF9kJ5K_uMX2s0L3lbtOjU00mHibYvSK_EfEa8XhSB2HaMgKgWebl0F5UHMO0iQ89eNWzI0r57rRIr5bPa-cjVbQzYvMJ4BTw.jpg) ![VelgoNyx 8Ah 20V MAX Replacement Batteries, 2-Pack, Lithium-Ion — 5](https://www.ofertitastop.com/i/IX4J7ildTNIDb0M4CNdgaudEYgRB8EFbp0yrEeyIxRIHLKVMZ0X22rJMvOhnIG-BcEB2E4goBgETbgZD9T0eeqAx7TV7op-5DvPVVxrZ16IABKdIxNfGplAdtA.jpg)
