MF super sealed battery

[ray 316]

The battery on my honda vision is flat and needs charging it's a MF super sealed battery CT 4L BS. Can l use a battery charger on a sealed battery and could someone tell me are these batterys 12v as l have no idea because theres no markings .

hi,
yes you can use a charger on these sealed gel type batteries.
there good batteries, but only when in constant use.
if left unused for a while, there knackerd!
for some reason, even the optimate will not rescue it.
damned expensive to replace as well, so just replace with a "normal" battery.
cheers,

Thanks for replying.
So are they 12v batterys.

Can l use a car battery charger to charge it.

So sealed battery are gel are they or do you get acid sealed battery also.

If the battery is no good after charging roughly how much would one cost...

A standard car charger would fry such a small battery. Get a slow charger such as:

The battery's flat with a reading of 11.86v and the trickle charger you put on here says it's no good for flat batterys but ok to stayed charged and top up. So is there a charger that will charge a complete flat battery, or could l use my car charger for a hour or so then switch of for a while then switch on again and repeat this till l have a charged battery to decrease the chance of cooking the battery with one charge.

Hi,
you might be better off investing in a decent charger.
like an optomiser?
one that will re-charge deeply discharged batteries & keep them topped up.
problem is there expensive.
charger =£40+
battery = £25 & charging it once on a slow charging car charger ~(like 1 amp) wouldnt kill it, if it was done the once.
I have a cheap car battery charger, feck knows where i got it, but its only 4 ah at max & 1ah on trickle.
done a few bike batteries (even 3 or 4amp ones) on trickle.worked fine.
Anyway, whats wrong with bumping the bike & then going for a ride to see if the battery charges up?
cheers,
GAZ

4 amp is way too much for such a small battery. The fast charge rate for a cell like that is about 2 amps.

the trickle charger would charge it in a few hours as its such a small unit.
