Trade-Shop Premium Li-Ion Battery 20 V / 4000 mAh / 80 Wh Replaces Worx WA3528, WA3553.2. WA3551.1 for Worx WG169 WG169E WG259 WG259E.9 WG549 WG549E.5 WG549E.9 WX166 WX166.4 WX166.31

Bought this for my Hydroshot pressure washer. It gives double the time of the standard battery and uses the same charger.

Just have to check screws on outside of case to vibrate loose specially when using the multitool

Use this for my Worx battery operated power washer, better battery life than the standard one that comes with it

Works ok, will let you know later if it's lasts for a decent amount of time.

Good product

Cracking product. Good price

Only used it once so far for my WORX mobile jetwash, but does what it says on the tin & more powerful than the one that came in the kit initially.Can’t comment on longevity yet, too new!
