Keeping a sealed gel batt n charge indefinately? Bad idea? Looking to run a car stereo in house.
Hi guys,
First of all I know ifs not techically in a car but it is related, so bear with me.
Im in the process of reoing my kitchen, and thought it would be a good idea to use a car stereo I've got lying round. Its a dvd mp3player so
would be handy to have. Only thing is how to power it. I first thought of using a big regulated power supply like a PC psu or similar, but if I wanted
to be able to store presets and be able to turn it on with the remote, it would have to be on 24/7. So then I thought about using a small sealed gel
battery (like those used in booster packs or burgular alarm) with a trickle charger keeping it topped up. It wouldn't have to be much, because
for the length of time the stereo would be on it would take ages to run down the battery. What does everyone use on they're cars during the
winter? If it works I could use the stereo to power a couple of waterproof speakers in the garden, and maybe do something similar in the garage
(I'd just like to use some of the stereos I've collected from my boy racer days).
Regards
Gareth

I'm probably missing something important being a little drunk but can't you just get a normal 240-12v adaptor from argos etc, cut off the
little minijack thing and solder on an adaptor for the stereo (either homemade or cut one of the halford stereo adaptors up)?

Wouldn't a car battery charger be more suitable?

Well not sure about the application you intend ..but to answer one of your questions....
When ever the car is not in use, I always use this:-
ctek xs800 linkydink
Whether or not it is suitable for your particular needs, I have no idea....

The stereo needs 10A to run properly, so would need quite a substansial 240-12v adapter. It would also need to be left on all the time to allow the
stereo to be left in standby mode as well as keep the stereo presets. So I think what I need is a 'smart' trickle charger to keep the
battery topped up without cooking it. I work with boats and they have chargers on them running 24/7, but they're big chargers capable of 20-30
amps and pretty expensive. So i want something, locost(ish) thats going to be reliable and not set fire to my house,lol.
Thanks for the fast replies.

See my post above and click on the linkydink...
Plenty of info about the different cteks....I have the 800 ..... But although you may not think it is lo(w)cost......I think it's worth every
penny...

i have a similar set up bt home. I use to do car electrics for a living and gathered some bits. I have a kenwood stereo inc 6 disc changer. It also
has a small amp. It all runs from a largeish pc power supply. I play cds and mp3. Im not bothered about turning it off because its on shuffle. Radio 1
is on preset 3 with one tap down on autoseek. I find it very good and useful! No problems to report
Track days ARE the best thing since sliced bread, until I get a supercharger that is!
Please read my ring story:

Personally i'd just go and buy a DAB digital radio - save all the hastle of trying to bodge a radio and speakers into a kitchen unit - which if
it doesn't work will just leave you with a redundant hole in your new unit.

If you want to use a battery and charger then you can but make sure that the battery is designed for continuous charging, such as yuasa NP series and
the charger is designed for sealed Gel batteries.
Its not going to be very cheap but try a local fire or security alarm company charger/psu £20-30 and 2 x 7Ah batteries £35.

I've been having a think and I think I'l probably use one of those cheap solar panels for keeping cars topped up. Would be a lot less
hassle, and no risk of over charging (not with the amount of sun we have anyway,lol).
Thanks for all the replies
