2 Pack 20V 5.0Ah Battery for Worx, ASUNCELL Li-ion Replacement Battery for 20V WA3551, WA3551.1 WA3553 WA3553.2 WA3641 WG629E WG546E WU268 WX166.4 Compatible with Worx Cordless Power Tools

I purchased two of these for my Worx leaf vacuum/blower as the two Ah didn't last long enough, I was sceptical about buying own brand ones, and not Worx originals, but the price was good enough to take a chance, these are just as good as the originals. giving a long run time at a fraction of the cost. I will probably purchase another two in the new year.

Really impressed with these great-value batteries.I have bought all my portable tools from WORX, and am generally very pleased with them. I've always bought them with batteries - so I have plenty of them, however for longer jobs, (I have WORX's superb strimmer and chainsaw), you churn through batteries every 20-30 minutes of hard use, and these chunky batteries really help.The batteries work immediately the same as the WORX ones, and they have a handy button on the back which lights up when you press it, and shows how much charge is left, (roughly).I've had these for about 3 months now, and have used them a lot, and they charge quickly, and hold their charge well if not used for a few weeks. Really recommend these. The WORX ones are great, and these ones are just as good, but a lot cheaper, and really handy as spares.

good battery not amazing as i was expecting and don't seem to have any more power over smaller ones but still cheaper

Batteries arrived with a good level of charge so topped them up and used them in my Worx Blower. Had a good session and ran until the over discharge prevention circuit cut in. Recharged again all without any issues. So happy so far

For the price of those batteries, I can't fault them. They last quite a long time. They do as they say. I've used them on both my strimmer and lawnmower and I can do the front garden (which is small) and our back garden (which is a good size 30m x 25m approx). Much cheaper than the real thing and does the same job.

Bought these to use with our Worx Lawnmower as I had been using 2 Worx 4Ah batteries, so these being more capacity I thought would last longer enabling me to do front and back lawns without having to recharge, unfortunately these don't last as long as the original 4Ah Batteries.

Spot on, charged them up on the worx charger, no issues.

Great upgrade from standard batteries. More power and longer charge
