Battery is less than a year old... Rapid charger light turns red after about 30 seconds and shuts down. I have 3 other batteries which charge normally... so not the charger. Took apart the battery... all cells look good from external observation. Asking if anyone has a direction I can go on before I take the control board off and examine. Thanking you in advance for any guidance
That sucks. Too expensive for premature failure. Can't offer insight into the Atlas cells. We have a couple of 40v Atlas batteries and they are working well after more than a year of steady use. I have an extensive set of 18v Ryobi ONE+ LiOn batteries, and I've had two similar cases where a battery died what I considered to be a premature death, where they charger refuses to charge them. That's out of about 15 batteries. I've never done a deep dive on the cause, but I suspect either a single bad cell or circuitry. Maybe the next one needs an extended warranty? Given the cost...
Thank you for your reply! FYI... This forum has BIG potential... looks like no one knows about it yet though.. spread the word I'm going to try juicing the defective battery from my DC bench power supply and see if that works before removing the control board from the battery... not only is it screwed on... it's glued on.. which I don't like. Anyway... thanks again!
I have 4 Atlas 80v batteries varying in age. NONE will charge on either of my fast chargers. I can charge all of them on a variable power supply (0 -50 volts DC) I just purchased TWO of the NEW high capacity 80v Atlas batteries. NEITHER will charge on these dubious chargers. The two new batteries cost me in excess of 400 bucks and have to be charged on my power supply. I just charge one 40 volt circuit at a time. I think it should be time for HF to stand up and realize that there is SOMETHING WRONG with their fast chargers and get them corrected and also, they should replace the ones that have gone bad. I am a loyal HF customer and hope that they do something.
Is there a reference on how to charge these with a variable pwr supply? I have a battery that has only been charged twice and it won't charge with my fast charger. At $100 each, 2 recharges is a very expensive energy source.
