Anyone own a Rolson's 12V Jump Start with Air Compressor unit?
Trust No One®
what is written on the back or send me a digital snap.
In my flat clearout I misplaced the mains adapter for the unit. I've found
what I think is the mains adapter but I'd like to be certain.
Any help much appreciated.
Cheers.

I'm using a charger from something of Panasonic's.
Output 13.5V DC, 400 mA, 9.2 W with the +ve in the middle.

Hmm.. the candidate adapter I'm looking at is labelled EMC (model WJB-DC)
and the output is 12V DC at 500ma.

It's unlikely to fully charge it. The nominal 12V of the sealed lead acid
that's 99% sure to be inside it really needs 14V or so to charge it.
If you try and charge it with a 12V charger you'll find it doesn't last long
at all.
But then again a lot of cheap chargers are unregulated - which means they
put out a voltage that can vary a lot with load. You'd have to measure it in
that case.
13-15V is what I'd look for, ideally 13.8-14.4.

Thanks for that. I'll keep looking.
Rather silly of me to have misplaced it :(

Mine is badged Tronic and came from Lidl at the vast cost of 20 quid a
couple of years ago but probably from the same factory.
IMHO because they can also be charged off a car system they will have an
internal regulator to prevent cooking the SLA battery. So a plain 12 volt
DC supply will be fine. Mine is marked 12V 1000mA DC

Isn't it badged 'Rolson'?

You won't do any damage by trying it. The charging indicator light
should go off when the battery's charged.
BTW be sure to charge it regularly. It appears these batteries don't
last as long as car batteries.

The one I have is not a Rolson it is branded as Bigmaster but it has a
12v 17ah battery and the mains adaptor is a model HB-DC 12v 500 and
rated at 12v 500ma.
Hope that helps

It should certainly be charged before storage if well discharged. But
shouldn't need routine charging - SLA batteries have a very low self
discharge rate.

Seems my Lidl cheapy was even more of a bargain with a 1 amp charger. ;-)

Your Rolson probably is this one:
http://www.yes661.com/prodDetail.asp?id=14939
This is a dead ringer to the "B Grade Portable Jump Starter & Air
Compressor" from Maplin, and is almost identical to the one from Halfords:
http://www.maplin.co.uk/Module.aspx?ModuleNo=49038&FAQS=Y&doy=2m9
http://makeashorterlink.com/?J10B21DAD (see the enlarged image)
So, you might as well pop down to your local Maplin/Halfords and take a
close look at its specifications and the mains adapter. If you need to buy
the adapter, unfortunately Maplin don't sell this accessory separately (as
in their answer to someone who also lost the charger and posted a similar
question like yours in the Q&A!)
Isn't it amazing the price differential?

The one I have suggests a full charging at least once every six
months.

I'd imagine a nominal 12v/400ma adaptor will probably give a bit more at
low load as the battery nears charge.

Yup - mine looks identical to those except for the black case and cost
19.99. Somewhat of a bargain. It's been used to jump start cars about a
dozen times and often for pumping up tyres.

Yep that would be the one.

75 quid!!
Talk about taking the piss! I bought mine for around 22 quid at my local
general store about a year ago :)
It is an extremely useful bit of kit. I've never needed to use it so far
(touch wood) but it is nice to have it just in case.

the plates have become sulphated, or possibly debris deposited below the
plates is shorting them out.
I'm no expert, but maybe the quickest way of finding out if the battery
might be recoverable would be to borrow an ordinary 'non-smart' charger,
and see if the battery voltage shows signs of coming up. If the ammeter
just sits there, pinned at maximum, it's likely that debris is shorting
the plates. If there's little charging current, it's probably sulphated.
Either way, there's little chance in getting the battery to recover.

to a traditional "transformer/rectifier type charger for a while but I
don't hold up much hope.
Brian Reay
the newer ones, tend to be small and claim capacities which suggest an
Li based battery. Recovering them is, at best, 'interesting'. You can
swap out cells but trying to recover cells (or batteries) by 'forcing'
them to accept a charge can result in dramatic results.
Even recovering sulphated LA batteries is hit and miss. I've tried in
the past but never managed more than a fraction of the original capacity
and, even then, the results have been short lived. Certainly, modern LA
batteries seem all but impossible to recover, the limited success I've
had was with older ones some years back. I was given some 'magic' pills
years ago- a bit like Batt Aids on steriods- they worked but I've never
seem them since.
MrCheerful
Bat aid pills are still in shops including Halfords, I used to sell them
in a motorcycle shop, but not recommend them, they were helpful on
little bikes with no real power requirements, but pretty useless on
anything with electric start.
For my sealey jump pack I cut the casing around and fitted a fiesta
battery in it, starts anything really easily. The original battery was
IIRC 14ah and cost about the same as a fiesta battery.
