barttery gone flat..any of these any good??
Hi all, I have a vardy sealed battery, and it has gone flat today.
im guessing it is because i havent used it for the last month.
I have been looking at trickle chargers, and wanted to know if any of these were any good please.
1st.
a solar charger, this i would leave on the fence, and connect to the car.
+ free energy
-as safe to leave connected to battery??

2nd
ctek charger.
+ safe for battery
- have to have mains power supply
http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_818863_langId_-1_categoryId_255205
what would the people of locostbuilders recomend please

ian

What makes you think the solar charger would be unsafe ?
I spent a lot of money on booze, birds and fast cars. The rest I just squandered.

if it is left on for a week etc, could it over charge the battery?

I was given one of those solar chargers a while back, I ended up binning it, unless you start from a 100% charge battery a solar one will not charge
it in time for when you need the car, or at least if you dont plan on driving the car for a few months, they simply do not have the cabability to
supply the current needed to charge a partial or flat battery. So with what you have given as an option, yet another one for the Ctec.

If you feel you are safer , get an decent ELCB circuit protector for use outside with your extension lead. BTW your batt specs are the same as mine,
exactly, this was the battery I tried the solar charger on !

thanks for the info all.
so it looks like a mains power supplyed one will be best.
is the ctek .8 a good vfm one, or would you recomend a defferent version/make?
thanks

Your going to get lots of options now, lol, but my choice was this, one thing to
remember is not to give a small capacity battery to much current, you wont get the life out of the battery otherwise, the one I choose was a small
900Ma one which is perfect for small batts.

That link didnt give a price
here's another one.

Yes 800Ma will be fine, will just be a tad slower than mine thats all.... I charge mine after every time I get home after a run, yes the alternator
does this but to get it to peak again I use the charger, takes about 10 mins to get it to 100% again, then if I dont use the car for a month or so, I
charge it every few weeks, takes around 5 mins then.

if i got the ctek .8
http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_818863_langId_-1_categoryId_255205
and then got this charge indercator panel
http://www.halfords.com/webapp/wcs/stores/servlet/product_storeId_10001_catalogId_10151_productId_738319_langId_-1_categoryId_255205#tab4
could the panel be used as a 12v power supply for sat navs etc as well?
thanks
ian
edited to say..
looking at it again, it looks like it is not a cig lighter style socket

To be honest, any decent 'intelligent' charger should already have the indicators on it, mine does, if you have to look at separate
indicators , I would elsewhere than the one you are proposing ( thats assuming it does not have them - hard to see with the photo there, but it does
have something on it)
As for the solar charger, I tested it to see what current it could supply, my own barely had the power to run three 10mm leds, now this was 2 years
ago, maybe they are better now I don't know?. It may have the current to keep a satnav charged but I doubt it would have the capacity to run it
wholey on that solar device.
If it were me, I would forget about the solar device and just get a decent charger with the charge state leds already built into it

Have you got any timer plugs. You could set it up to charge for 1 hour a day so it doesn't overheat the battery as even intelligent chargers are
not perfect if left on for really long stints as found at the bike shop.
yours, Pete
I went into the RSPCA office the other day. It was so small you could hardly swing a cat in there.

I went for a ctek 0.8 in the end with a panel mounted display, so i can keep a eye on the levels with out having to connect anything up.
will post some pics when i fit it
