yes I know, that is what the bulb is for to keep the voltage constant, the charger itself keeps the curent constant
AS I SAID BOAT model boaters have been using this methoud in our are for years, with no problems..

So if you knew this, why did you not post up and offer the best advice as the op asked for?
I'm am somewhat offended by the tone of your reply to mine......
Perhaps I ought to keep my opinions to myself in future?

Play nice guys. I am sure this was just a simple misunderstanding on tone. Written word doesn't translate very well. Shake hands :med:

Car type battey chargers are not constant voltage or current......
I referred the op to view the manufacturer's website for recommendations on charging to ensure longevity of the battery and to ensure personal safety is not compromised..

Hi Chris
you may know from the previous posts the charging requirements for lead acid batteries and sealed lead acid and gel batteries are quite different .As for me i took the easy way out and went to Argos and bought an eight Amp automatic charger with a switched setting for gel batteries or normal lead acid and also a switched trickle charge it has been used a lot to charge up some hefty ex wheelchair sealed gel batteries and also some smaller ones that i use for amateur radio operation whilst operating portable from some remote hilltop hope this has been some help to you.
Cheers Paul
