Lithium Ion Battery 36V 2.0Ah Convenient Compact Rechargeable and Versatile, BL20362-XJ

Originally bought in 2016, my Black and Decker strimmer had been flagging over time, giving me barely 10 minutes of life before fizzling out. Since there was nothing wrong with the strimmer mechanism, and new ones are not cheap, I decided to chance a new battery. It's been a revelation. The run time is noticeably longer (about 25 minutes), but even more importantly it's back to its old power. I hadn't noticed over time how much weaker the old battery had been getting, even on a full recharge. And, provided you don't completely drain it, the battery takes about half an hour to recharge, which is much quicker than the old one.This strategy probably wouldn't have worked a few years ago as replacement batteries have been very expensive, but prices seem to have come down. At £58 it's still not cheap, but it's bought me a few more years of strimmer life. I'm very pleased with my purchase.

So far charges well and works well. Fits the kit and lasts well. Very happy with purchase.

I bought this replacement battery in July 2023. I own a B & D strimmer and a hedge trimmer, purchased in 2016. Both good product. Last year one of the batteries failed which I thought was not unreasonable after about 7 years. The replacement battery worked well up until a few weeks ago when it ceased to charge properly. I guess I was lucky that it failed before the expiration of the warranty.I sent a claim to be B & D who handled everything very efficiently, arranged free-of-charge collection of the faulty battery and supplied a replacement a couple of weeks later. Reading reviews here I see that number of people have had failures of batteries purchased in 2023 and I wonder if there was a bad batch. My other battery purchased in 2016 still seems to be going strong. It was disappointing that the battery failed but the warranty replacement was exemplary. Make sure you keep proof of purchase documentation such as the invoice which can be accessed through Amazon.

Battery is perfect. Replacement for the original which died before my mum even opened the box. Parents, who’d have ‘em?!

Can’t fault the battery, but don’t make the same mistake I did. Ordered the B&D 36v strimmer, which didn’t come with a battery. Amazon suggested adding a battery, so I did. All turned up as expected and you’d have thought one of them would have come with a charger!!!! Oh

Awful!Wouldn't charge beyond 1 'green square" after first use. Failed to charge at all after that. Absolutely dead.Original battery supplied with strimmer lasted for only 15 months (half of which was winter).Dreadful product spoiling otherwise good equipment. Zero star rating if that's possible.

This was to replace my old battery which had finished it's life. It performs as I expected and is quality.

Put off buying an extra battery because of price but this 40% off offer to good to resist.,ordered late afternoon delivered next morning!Not tried out on lawnmower but mighty impressed with customer service. I really like my B&D cordless lawnmower but increasingly frustrated with battery ability hope a new one fixes the problem.Update.Used today ( April 22) for the first time, worked fantastic but not on offer anymore. For once I did something right!
