Replacement for black and decker 36v battery BL20362-XJ BL20362 BL2536 BL2036 BL1536 LBX2040 LST540 LCS1240 LBX1540

[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.

This battery works better than my original one that came with the strimmer. It's 40w on a 36w machine, but it works better and lasts longer.

This is a waste of money. I didn't want to buy the Black and Decker one as it's so expensive but this lasts 5 minutes on Eco. Frequently flashes red on the charger even when it's been charging on green initially and isn't fully charged.

First battery that came would not charge. Contacted seller through Amazon and they arranged a no quibble replacement to be sent out by return. The replacement charged up with no problem. It fits and runs ok on my strimmer. Not tested at length or run down but having charged up as it should, hopefully it will be fine. Would buy again.

Also fits the charger I had for the 36V battery. Fits the strimmer and excellent power and run time. Excellent buy.

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.

Great price and works well, easy to charge and holds charge well.

On the basis that reviewers tend to only surface to write something negative about a product, I ignored the warnings about the product finishing it's charging cycle with a flashing red light on the charger. Should have listened, as that's what mine has done on the very first initial charge after receiving it. It seemed to charge ok though so persevered. But the charge didn't last as long as the branded battery that came with the mower and after 4 or 5 charges gave up the ghost. Contacted Geelink a few months down the line and their answer was, buy another one then. Do yourself a favour and pay another £12 on a genuine one.
