Many thanks Gary. I was quite easily able to dismantle the unit, thanks to your great video. Like other comments here, my unit is about 5 years old. It has been running quite slow and cutting out frequently. I tested the battery after I opened the unit and it appears that there is a low volts cutout which kicks in at 3.2 volts. My battery was dropping to this voltage quite quickly. New battery on the way.
I’ve had mine for ~10 years and am now replacing the battery. It’s been unusable cordless for a while, but thankfully still works corded (some models only use cord for charge and you can’t directly power the unit). Thanks to this video I have it neatly apart with almost zero damage and now just await my battery to arrive. Apart from the obvious engineered non-repairability of it, it’s a good unit and I’m glad it will live on for a few more years. I’ve heard that leaving these on charge will quickly damage the battery as there likely no charging shut-off curcuitry so overcharging is easy. I’ll certainly only be charging till full and unplugging immediately with this new battery.
Overall Lithium batteries won't last more than 4 years on average. I'm sure it has a cut-off voltage charger otherwise the battery would swell and possibly catch on fire. The sad part is we all know this trimmer can easily last for many years and should have been designed for a removable battery. This is not like a phone where it gets out of date with CPU/memory.
I cannot live without this device I have been using for years, people always ask me who cuts your hair ? I don’t have any as I used it without the guard . The Remington is the best but recently I saw knock off brands on Temu and I bought very cheap under $10 and it works fabulously . I could live without RU-vid ads which will not let us watch in peace
Guys this is very important, at 8:25 when he takes the little spring loaded hold downs off, there is a 2nd piece that goes in the slot that if you lose that, or in my case didn't even see it, you can't hold in the trimmer head and the spring won't have anything to rest in. I do not think you even need to take the hold downs off.
Thank you for showing us this... its a ridiculous price $60 to pay for this.... battery sucks. This product was engineered to have a bad battery and a pain to replace. Shame on Remington.
It's not a bad battery, no current lithium battery lasts more than 4-5 years on average. The design from Remington is to fault, they could have easily made this a replaceable battery. But these days who does make replaceable batteries? Look at the phones and tablets. Apple started the trend and everyone follows Apple.
Sadly , I think I’m more likely to either brake the case or injure myself in the process of getting that casing off. It’s so annoying that manufacturers make stuff to be thrown away instead of being able to repair /replace parts .
I'm seeing that the blue plastic batter case cover has a tab on the back of the clippers. That area does have what looks like a point of entry on the main case (as you begun). I wonder if unclipping that would remove the whole thing allowing you to skip that difficult part in the beginning of the video. Maybe not though.
For anyone watching this and trying to get the first piece to pop off. First pop the back side seam off by the power button. Then take the took and pop out the two clips on the bottom. You'll see them on the red part and pop those clips out. The cover pops right off. And yeah, take the blade off first.
Hi My HC4250 having less than 2 years but doesn't charge anymore. The light doesn't bling when I plug it on the charger link. Could you confirm that it's the same symptom from the battery issue ? Thanks
I dont understand the complaints from some people that had for 4+ years. Its a cheap, wireless device. 4 years of weekly use for 50 bucks is a literal fraction than paying a barber to cut your hair. Youre technically spending like 15 bucks a year for a haricut. And I think Remington has a 5 year warranty on these things.
It could be easily designed to have a replaceable battery. It's not like a mobile device that is super thin and water sealed. Nothing is repairable these days, they do it intentially for sales.
I agree, however, the device could easily work even longer, there's no reason this battery couldn't be easily replaceable. To simply throw it away is pretty wasteful when there's nothing actually wrong with it.
