Great vid, will get on to sorting mine now! Thank you for taking the time to film and share this. Love the clarity and lack of disruptive music!

What a great video! Very well done. Straight to the point and not over-complicated. Easy to follow.

Thanks John. A real informative video with no annoying background music!

Thanks John. Very useful. My 200 has exactly the same symptoms so will follow your suggestions. Even as a mechanical incompetent think I might be able to do this.

Great video, thanks. Forget buying a replacement internal battery from Halfords. Instead buy a decent Lucas 12V 22Ah/20Hr (ref; LSLC22-12) often used on big lawn mowers and about £45. 10% more Amp Hours too.

Great video , I’d have been tempted to return the battery for the correct one though, but a really good video mate well done

Cheers for the video, simple job for a decent saving £££ Hope the weather has improved!

Thanks for this. My battery is a sunnyway SW12200 (12V20.0Ah)

Super filmy godne polecenia.

Nice video, I have almost the same model (led light rather than fluorescent) with same issue and will follow your lead :-)

Thanks brilliant video

Very helpful, thanks

well done

Thank you. Most helpfull.

someone gave me the 100 version of this power pack and the battery had only 0.6V across it...so i removed the battery and charged it with an external power supply using about 30V and slowly but surely the battery is now charging ok.

Thanks for that John I will sort mine out now. I managed to source another one a lot cheaper £24.22 and it is made in Japan.

Thanks John Rogers, I have just found this great video and have managed to replace the Battery in my Powerpack which stopped working 5 years ago and has been in the loft ever since. It is now charging up and fingers crossed all will be well. I googled for batteries and got an identical one but different brand for £51.99 on Amazon. If anyone is reading this is there any advice for replacing the fluorescent tubes. There appear to be no markings on them and I have lost any instructions and I am unsure what rating they are. Thank you.

Thanks I have the same charger you show paper code of battery it can work with all same charger the same you have I have it

I've got one which has an issue, The Battery isn't brilliant but it is useable for the time being, I believe mine has a problem with the Charging Circuit, The original PSU died and I found one that seemed to do an adequate Job, I believe I made the mistake of plugging in a PSU which I thought was the correct one and all I heard was a Relay constantly clicking, I quickly removed the PSU and now after finding the correct one it's still not happy charging the Battery, I'm wondering if theirs an internal Fuse or if the Relay itself has popped, When I connect the correct PSU that I was using the LED comes on but remains Green regardless of how much Charge is in the Battery, It doesn't flick to Orange like it used to do? At the moment I can charge mine using My Big Absaar Car Charger and it seems to do the Job fine as long as I don't select fast boost on My Big Absaar Car Charger, It doesn't matter how long it's been on charge for but when I press the Test button on the Powerpack it just displays the first 2 LED's, Please see Pic and thanks for any and all help offered: www.aj-cs.co.uk/pics/powerpack_200_faulty.jpg

My battery is 12v 20ah. Can I use a 12v 30ah. I want more power when I go camping with my powerpack

Great video thanks for taking the time to make it. Did you try to recover the old battery with a Optimate /smart charger? Can you charge the battery via the jumper leads? UPDATE I have just charged my 5 yr old booster pack with its standard charger and the voltage was 12.6 v I then charged it on the optimate 6 charger using the two jumper leads and the voltage has increased to 12.9 v ;)

I changed the battery on my power-pack and it is still doing the same with a new battery, says it’s fully charged but it never is, anyone got any ideas?

I replaced the battery in mine and it was beeping so I plugged it in to charge, the light turns green but as soon as you remove the charger it beeps again

OK good. Seems a shame you didn't check out if the battery has dried out.

Hi there this is Dave I've just watched you change your battery on your powerI have a question for you have you ever had to change your fluorescent tubes and where did you buy them from hope to hear from you this is Dave thank you very much bye

I have this exact power pack Halfords 200. I seem to have lost the accessory leads including the power charger lead too. I did go to Halfords to attempt to order a new set of accessory leads, but they said they have changed to new power packs and they don't stock these leads anymore. dose anyone have a set of accessory leads and charger lead too. Will to buy from you'll, or if you know a store outlet thats sells them,. Great Video too, thankyou

Here is the link for the battery. www.componentshop.co.uk/12v-20ah-sealed-lead-acid-battery.html

What's the specs on the power supply charger ? Voltage & amps. I've got several that all look the same and can't remember which one it is.

Does anyone know where i can get replacement parts for the compressor on this powerpack ?

I have the same power pack. The battery is charging and all functions of the pack are working fine apart from the compressor it won't turn on at all....any ideas on this.??

www.tayna.co.uk/jump-packs/batteries/pl1700/ fits. I've got a s/h one with no mains unit, open the back and put a normal battery charger on ( at low current setting)
