    • Better than BLi22
Size: B140 Battery-40V
So far so good. Lasts longer and better priced than the old BLi22. 4 status lights instead of 3 is a bonus as well.

    • Works for larger Chain Saw. Wish it was cheaper.
Size: Bli30 Battery-40V
This is the correct battery for the chainsaw. There are a few others in this series (BLI-22) but this is the larger battery that came with the chainsaw. The smaller ones work, but don’t give as much battery life. Great for the hedge trimmer or blower, but only about 20 minutes if cutting with the chainsaw. This one is good for about 45 minutes to 1 hour of on-again-off-again cutting. It makes using the chainsaw in remote areas more reasonable - because a single battery dies out before the work is done. Two batteries is about right before you need to sharpen the chain and maybe clean out/reassemble the chainsaw anyway - which is when I’m usually about done physically and mentally. I have another BLI-22 battery, but I’ve never resorted to it…I’m usually exhausted after 2 battery’s worth (2 hours cutting). I just wish these were cheaper. At over $300 a pop, they seem excessive. It’s almost worth just buying a second Husqvarna electric chainsaw…because 75% of the cost is battery, and I’d get a spare chainsaw! Dewalt seems to be able to produce a battery for cheaper, they basically subsidize the battery for you to get their tool. I wish Husqvarna was honest about the REAL cost of this tool combo. You have to spend nearly 200% the cost of the tool to do a day’s work. But I like the chainsaw and the battery is actually great- built well, sturdy, and has battery management system built in. Maybe that’s what the $$$ is for. Overall, works great. Just wish it was cheaper. With all the battery tech out there, this feels like it should be $150 max. ... show more

    • Bum Battery & Husqvarna knows it
Size: B140 Battery-40V
Review Image by Tim Rozier Tim Rozier
Blatant False advertising!! This battery does not replace the BLi22. I have had 2 Bli22 and they both run my Husqvarna 220il Weed wacker as they should. Bought this one that says it replaces the BLi22 battery but it does not. Oh yes, it fits fine into the battery slot and all the plugs line up and insert as they should. The light turns green when power on, and when you pull the trigger...only 5 seconds of that wonderful whirling nylon line sound and then silence; it's dead. No restarting, nothing. You can try to restart it and you get another 5 seconds or nothing at all. I've called Husqvarna customer service, talked to a technician and he said it should work (after checking with some anonymous background person). I took the battery back to my local certified Husqvarna dealer and after he tried to start it (and failed as I did), he said he would exchange it for a new one with the sales receipt and registration. Got a new one from him and rushed home to try it and...nothing. It did the same as the old one. I was almost tempted to do target practice with the bum battery with my 12 gauge Remington but a brief angelic calm suddenly got my attention. Final words... if you have $189 + sales tax to throw away, follow your heart. If you want a replacement battery for your weekend warrior tools, stick with the BLi22. ... show more
