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 out of stock at the last check (3 of 4), but 20V 1-Pack 4.0Ah Lithium Battery for Snow… is listed. 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?.
Questions
Can I still buy the 20V 1-Pack 4.0Ah Lithium Battery?
It was out of stock on Amazon when we last checked, on 2026-09-08, and Amazon did not say whether it would return. Stock does come back though, and this page is not rebuilt every day — the Amazon link above shows the current position.
Does it come with a battery?
The listing does not state that a pack is included. Most of ZEGJAW's standalone 20V packs are discontinued, though at least one is still listed — see the battery platform section above.
Will ZEGJAW 20V batteries from another tool fit?
ZEGJAW sells one 20V pack family and describes it as compatible across its 20V tools. The listings also claim Makita compatibility and never mention DeWalt.
Who makes ZEGJAW?
ZEGJAW names itself as its own manufacturer on the listings and publishes no parent company. There is more on that in the brand guide.
