|

The battery on my old van has gone flat through non-use. Fitted the extaension cable and the charger (bought from Halfords, Bath in 1974ish),
Now, as the battery is as flat as flatcould be, I thought the ammeter would be up there in the 5s or 6s but it is just off the bottom stop. I thought a flat battery would have soaked up the amps, so why isn't it at a higher reading?
Tis working, I can hear it buzzing internally. Perplext of Wiltshire.
Cheers, Tony. |

I realise this isn't stricktly "restoration" in the normal sence of the word, but I'm trying to restore my battery to fully charged!
Cheers, Tony. |

It's one of those new fangled sealed cell/unit jobbies.
Cheers, Tony. |

If you have run it to completely dead flat, a trickle charger will not be man enough to get it started again. I've had this problem a few times when an interior light got left on.
Only procedure for a quick fix is to connect another battery via jump leads and give it a bit of a boost from the alternator from another motor. Once you have just started the process with about ten minutes of running you can then leave your trickle charger on overnight and it should be OK.
Other option is take it to a battery shop and get them to put it on a fast charger.
Voltage equals electrical "pressure" and you need a bit of pressure to start, like blowing up a balloon. It gets easy once it's started but resistance then grows as it becomes charged.

Tony,
The 'New fangled sealed jobbies' usually do have filler caps but they are hidden under a plastic sticker. They have to get filled with acid somehow.
If a battery is left in a discharged state a condition called sulfation sets in where the plates harden with lead sulphate. There is no know/proven way of recovering from this state and replacement or replacing would be the way to go IMHO.

Many thanks for all those informative replies. As my old van has only months of wear left in it...I don't think I'll bother to invest in a new battery but just flog on.
Thanks once again. Cheer, Tony. |

I have a unit similar to this wired into the Singers batter
http://www.ringautomotive.com/uk/products/Cars/Battery+Care/SmartChargers/RSC601
As it is hard wired and uses a plug and socket between car and charger it only takes seconds to plug in once parked in the garage. Ensures a charged battery every time the vehicle is needed.
Well worth the investment
