36V 2.5Ah BL20362-XJ battery for black and decker 36v battery

Despite indicating fully charged my 36v Black & Decker battery seemed to drain its power after only a few minutes use. In fairness it lasted a few seasons but faced with paying out £60 - £70 pounds for a battery that isn't compatible with any other equipment I have and the spate of poor reviews regarding life I purchased this one from Geelink at under £40. Against the B & D product rating of 36v 2.0Ah this one is marked 40v 3.0Ah and what a revelation! After 30 minutes of hard use it was still showing 2 bars and I was able to finish the job without recharging. Very pleased and would recommend.

Make sure you have a 40V charger not 36 or the charger can fail to fully charge the battery.

Worked fine for 6 months and then would not accept charge. Took this up with the manufacturers who just said I need to buy a new one. If I do it certainly will not be from them!

So far the battery has worked very well and is actually more powerful than my previous one. The strimmer has had a new lease of life and cuts through the grass much quicker.

I struggle to understand what battery can be used with different tools. I spend time trying to understand what the differences are and what do I need? What I do not find confusing is the cost involved, invariably the price charged by a manufacturer who just sticks the company ‘s logo on the battery is way more than an unbadged battery. This battery cost roughly one third less than a Black and Decker battery and is very good. It hasn’t caused any harm to the strimmer and we now have the convenience of two batteries. No downside, if your dithering, just go ahead, you won’t regret it.

[June 2024 update 1 year on - NO PROBLEMS VERY GOOD INDEED, only miffed see at £37.99 it's £2 less to buy presently.] Fully compatible my much loved & used GLC3630L20 strimmer & charger (also on newer BCSTA5362L1-GB which I since had to buy). 1st impression after 4 full charge/discharges it works better than the original mercurial B&D battery ever did. Warning - if your similar strimmer is 2016/7 you are likely best to replace it entirely rather than new battery. Had a tangle with hidden nylon & wire so took apart head for 1st time. It needs new motor spindle gear & clamshell set so that's £50 and the upper clamshell is also ropey. Can't moan as I've really used this tool a lot. I've made do a fix using bottom of a beer can but it suited me to spend 4 hours fiddling about. Update - that only lasted a month so bought a new strimmer kept this battery & old charger sold the ones that came with recent purchase. This battery is 5 star.

The last one lasted 3 years which was much better than the original B&D battery. Used on battery operated lawnmower so gets quite the work out!

I purchased the Geelink 36V battery in May 2023 as a replacement for my B&D Strimmer battery. Now, August 13th, 2023 it's faulty. First few charges were fine then latterly the charge started to drop off. Battery now barely holds charge more than a a couple of minutes. Avoid this battery......
