Crawfie Posted July 30, 2021 Report Share Posted July 30, 2021 (edited) Need some guidance …. I have a 12v power pack which is emitting a loud beep noise . This has been going on for 3 days now . The 12v light still works , but the charge dial is showing as being flat as a pancake . When I plugged the charger cable in yesterday the charge light did not come on. I tried today and it is . I use the pack to give us power in the house when we have power cuts and on rare occasions when the car batteries are flat . Is It knackered ?

RobH Posted July 30, 2021 Report Share Posted July 30, 2021 According to the instruction book, the beeping indicates either a low battery or connections reversed (when used for jump-starting). I see it has an internal sealed lead-acid battery rated at 38Ah. That being the case, at ten years old it is quite possible the battery has had its day - they don't last forever. It is possible to replace it according to the instructions: https://www.manualslib.com/manual/596668/Clarke-Jumpstart-4000.html?page=7#manual Quote Link to post Share on other sites
stillp Posted July 30, 2021 Report Share Posted July 30, 2021 I agree, after 10 years the battery might well have failed - if it doesn't charge it's probably time for a new one. Pete Quote Link to post Share on other sites
Crawfie Posted July 30, 2021 Author Report Share Posted July 30, 2021 I’ve just checked and the charging light is still on and the beeping has stopped. I’ll see what happens . Most probably get a new one before winter comes . Thanks for the replies . Quote Link to post Share on other sites
Malcolm Tatton Posted July 30, 2021 Report Share Posted July 30, 2021 I have one with a failed battery, but can't bring myself to throw it away. When I looked at replacing the battery, the correct replacement was more expensive than a new powerpack so I just put it away again! Quote Link to post Share on other sites
tthomson Posted August 9, 2021 Report Share Posted August 9, 2021 There are Lithium Ion battery based starter packs that are relatively low cost. ( I bought one for £35.00). These have the ability to start up to a 3 litre engine, but are small and light enough to carry in one hand. I keep mine in the boot of whichever car I am driving. It can also provide power to a laptop or other electrical equipment. It does not seem to need charging more than occasionally and comes with the appropriate leads (including jump leads). I bought it via Amazon. Despite not wanting to buy Chinese, they are all from China. TT Quote Link to post Share on other sites
Crawfie Posted August 10, 2021 Author Report Share Posted August 10, 2021 I’ve been looking at those . The power pack has stopped beeping and is showing charged . See how long it behaves itself !! Quote Link to post Share on other sites
Deggers Posted August 10, 2021 Report Share Posted August 10, 2021 (edited) I did away with the lithium battery charger some years ago, in favour of a battery-less super capacitor jump starter pack. It doesn't need pre-charging, it's small enough to fit in your glove box . . . and it's got me out of a tight spot on several occasions without fail. I have the Sealey Electrostart 800, but there are a number of similar products on the market. Here's a similar jump starter, in real time.
