Remington Trimmer HC4250 replace the battery

[@caspertoo]

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.

making devices that snap together with obviously no intention on letting people replace a batter should be criminal.

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 This is not like a phone where it gets out of date with CPU/memory.

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 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 KZbin ads which will not let us watch in peace

Hi Gary, Thank you very much! by watching your disassembling video I managed to replace the battery without any damage. THX Haim

[@mattg.8780]

So glad you made this vid. These trimmers are best I’ve ever owned. Now we can make em last forever

[@GaryQuiring]

Thanks, I also love this trimmer. No more waiting at the local barber.

[@sebastiangheorghiu4751]

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.

[@GaryQuiring]

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.

Dude thanks for this video! I'm having problems with mine and can't wait to open it up and replace it. Appreciate the detailed teardown 🙏

[@tamayaytam]

Thank you mister. This is a real public service.

[@vincentbeales3302]

Great video! I'll be doing mine shortly. Demolition derby!

[@davidferguson8478]

You should use a battery spot welder for those types of batteries

[@GaryQuiring]

The average person is not going to have one.

[@ChiJo-l3i]

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.

[@databasebaseaustralia2096]

Many thanks Gary.

[@Thesharkfin1968]

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 .

[@GaryQuiring]

I 100% agree, there is no reason they could make this with a battery compartment.

[@ksfurlover2]

Thank you for the instructions ! Perfect !

[@mr_mr]

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.

[@uygar2580]

My trimmer is about 4-5 years old too, need to replace battery i think. It's working a bit weak...

[@Fozzee.1970]

Clean the inside of the blade regularly as the motor gets stuck with all the gunge inside. It can seem like the battery is failing but it isn't.

[@richardblanc178]

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

[@GaryQuiring]

That does not sound like the battery, more like the power brick is bad.

[@richardblanc178]

@@GaryQuiring thanks you.. I’m looking for test it

[@GaryQuiring]

@@richardblanc178 All you need is a volt meter. Check the voltage it should be 4.5 volts.

[@mikepga1]

I’d rather spend $55 and get a new one

[@mrshihtzu]

thank you

[@ibrahimjuma4806]

I won't bother to replace tge battery. I will continue to use the clipper with the wire lead on.

[@SuperCDS1]

Why didn’t you replace it with a 26650 ?

[@GaryQuiring]

Did you watch the video? It showed 14500 battery is a tight fit, the 26650 you are suggesting is a much larger battery that would never fit.

[@drillport]

Cheers

[@Dr.Lemmy_C_Yabum]

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.

[@GaryQuiring]

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.

[@Dr.Lemmy_C_Yabum]

@@GaryQuiring yeah, I agree with that for sure.

[@onemorechris]

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.
