The ZEGJAW 20V 1-Pack 4.0Ah Lithium Battery for Garden Cordless Power Tools is a 20V cordless battery pack, sold by ZEGJAW on Amazon under ASIN B0CRTTSHC4. Everything on this page is read off that listing — the specification table, the bullets and the photographs are ZEGJAW's own, and the comparisons are against the rest of ZEGJAW's range rather than against a marketing claim.
This one is currently unavailable on Amazon — the page is kept for the specification, and for what to buy instead. Within ZEGJAW's batteries and chargers it is the most-reviewed of 4, and 2 of those 7 are still sold.

Important Battery Maintenance Notes
For optimal battery preservation, please avoid charging it for more than 6 hours at a time. Additionally, fully charge the battery before its initial use and never leave it charging overnight, as this will severely shorten the battery’s service life.

The 20V battery platform
5 other ZEGJAW tools still sold run the same 20V pack, so a spare bought with one works in the others: 18" 20V Pole Hedge Trimmer Cordless, 20V Cordless Electric Tiller…, Leaf Blower & 12-Inch 20v Cordless…, 20V 1-Pack 4.0Ah Lithium Battery for…, 20V Lithium ion Battery Charger Fast….
Spare packs are still buyable — just barely. Most of ZEGJAW's standalone battery listings have been discontinued (3 of 4), but 20V 1-Pack 4.0Ah Lithium Battery for Snow… is still sold. The fast charger is also still listed.
ZEGJAW's own listings describe these packs as compatible with Makita and never mention DeWalt — the question comes up often enough that it has its own page: Are ZEGJAW Batteries Compatible With DeWalt?.
