LabTEC 20V 4000mAh/4.0Ah Replacement Battery for Worx 20V WA3551, WA3551.1 WA3553 WA3553.2 WA3641 WG629E WG546E WU268 WX166.4 WX372.1 WX800 WX802 WX678 WX550 WX523 WU531.9 WG894E WG629E WG329E

Excellent battery. Fitted to my Worx landroid mower and works perfectly. It's been on the robot all summer and never failed. Cost a lot less than a Worx battery and just as good. Excellent value.

Bought this as a backup for my Worx 20V pressure washer. At £25, it's less than half the cost of the original. Used it to clean pathway and slabs in garden instead of the actual Worx battery. I use my McGuires 5 gallon car washing bucket as the 20V pressure washer empties a regular bucket in no time. I'd estimate that I managed to use up about 25+ gallons of water before the battery power began to go. Overall I'm happy with this as an aftermarket alternative to the original battery pack. Only used it once so can't comment on it's long term lifespan. It operated without overheating and charged back up fully with no issues. Like the genuine Worx battery it has a battery level indicator, which is a useful feature. My main use for the Worx pressure washer is car washing and usually uses up about two 5 gallon buckets for initial rinsing of the car and soap removal after hand washing. Well within the capability of this battery. I'm very happy with the quality and performance of this cheaper alternative. I may update this review when I've used it for a longer time in order to report back on long term ownership.

These Batteries seem to perform well, the only comment being that they fit slightly loser in the appliance and charger compared to the OEM, that said they are secure enough and have charged with no problem. Quality of construction seems good. I have a lot of 40V appliances so these will get a good test!

Very good quality and excellent price

Very good copies of Worx fit batteries for powershare tools, work with every tool lasts just as long as originals, zero issues with charging, lovely price at moment, recommended 👍

They last as good as the original but a lot cheaper. Was worth getting because I have a lot of power tools that take the same batteries so they power them all.

So far so good. Some have complained about runtime but no issues for me. Nice price as well. Will probably get another pair.

Works fine although not sure the mAh is correct

Werkt perfect voor alle worx accu apparatuur

Je ne vois pas de différence avec les batteries d'origine. C'est p'tet à la longue dans 1 an ou 2, il faudrait que j'actualise mon avis. Mais pour l'instant, je recommande. Rapport qualité prix imbattable

La uso en una desbrozadora WORX de doble batería y me dura mas o menos como las originales. Lo único malo que el pulsador para saber el nivel de carga está del otro lado de las baterías. Lo recomiendo.

Très bon rapport qualité prix. Elle marche très bien avec mon landroid , la durée de de tonte est d'environ 1h30, aussi bien qu'avec celle d origine .

Semble identique a l'original. A voir a l'usage si elle tient aussi bien. En tous cas la finition est top
