Old batteries I had to charge half way through doing the lawn, these new ones just keep on going, very good purchase ### ⭐⭐⭐⭐⭐ very good does what is supposed to do *by on Reviewed in the United Kingdom 18 July 2026* very good does what is supposed to do ### ⭐⭐⭐⭐⭐ Expensive, but 100% worth it. *by on Reviewed in the United Kingdom 10 June 2026* These original WORX batteries are great. I made the mistake previously of buying some cheaper 5.0Ah after-market batteries for my Garden Vac, but these still couldn't power my equipment for even one pass of my relatively small garden. Got these 4.0Ah WORX batteries and I've done my garden 3 times on just one charge so far... "buy cheap, buy twice" I'm afraid. I would recommended the WORX originals. ## Frequently Bought Together - Worx WA3644 PowerShare Pro 20V 4.0Ah High-Capacity Battery with Battery Management System & Intelligent Power Control - ANOITD WA3875 Replace Worx 20v lithium Battery Charger Compatible with Worx 20v Batteries Wa3757 Wa3578 WA3525 Wa3522 WA3544 … - Worx 20V Power Share Reciprocating Saw - WX500L.9 (Tool Only) --- ## Why Shop on Desertcart? - πŸ›’ **Trusted by 1.3+ Million Shoppers** β€” Serving international shoppers since 2016 - 🌍 **Shop Globally** β€” Access 737+ million products across 21 categories - πŸ’° **No Hidden Fees** β€” All customs, duties, and taxes included in the price - πŸ”„ **15-Day Free Returns** β€” Hassle-free returns (30 days for PRO members) - πŸ”’ **Secure Payments** β€” Trusted payment options with buyer protection - ⭐ **TrustPilot Rated 4.5/5** β€” Based on 8,000+ happy customer reviews **Shop now:** [https://www.desertcart.co.za/products/615725117-worx-wa3644-20v-4-0ah-powershare-battery-20v-4-0ah](https://www.desertcart.co.za/products/615725117-worx-wa3644-20v-4-0ah-powershare-battery-20v-4-0ah) --- *Product available on Desertcart South Africa* *Store origin: ZA* *Last updated: 2026-08-20*
