Charging the ignition battery whilst connected to a T6
- Thread starter ShazzatheChef
- Start date
I used my oxford oximiser (similar battery charger for looking after my motorbike battery), but only to just make sure the battery is topped up after sitting for a while and doing local journeys. Put in a max of 0.85A through the cigarette lighter. It's not really a charger, it'll work as one but will take ages
Typically I read this post after having my battery on charge for 10 hours yesterday, connected directly to the battery terminals.
I don’t appear to have done any damage, the Ctek manual does show connecting it to the terminals unless charging a battery that’s inside the vehicle.

I connected the black wire to one of the bolts near the bonnet hinge. Seems to be okay.

Battery Chargers - How I Did It - So its that time of year again, cold, rainy. . . . . . . flat battery =[ This time we look at Battery Chargers. Our vans will most likely come with a AGM style starter battery, for this type of battery we need a "Smart Charger" . . . . but what does this...

"how long would it take the alternator to charge the battery?" - The alternator could deliver 140A, but the battery would only accept a max of say 20A which would reduce as the battery SOC increases (due to internal resistance and battery chemistry).
Absortion time should be taken into account "C rate" , so you would still need to drive for 10 hours or more to fully charge a flat battery.
"Is there any advantage to driving as opposed to just leaving the engine idling?" - EU6/5 van with stop start have an energy management system that controls the alternator output and charge rate. . . . . so yes and no. The ECU will raise the RPM at standstill if a high demand is required, but the engine is more efficient at higher revs.
a 90Ah van battery would take a 5A charger 18hrs to charge fully (90ah / 20A = 18hrs (theoretical))
a 90Ah van battery would take a 10A charger 9hrs to charge fully (90ah / 10A = 9hrs (theoretical))
a 90Ah van battery would take a 20A charger 4.5hrs to charge fully (90ah / 20A = 4.5hrs (theoretical))
a 90Ah van battery would take a 0.6A charger 150hrs to charge fully (90ah / 10A = 150hrs (theoretical)) - that 6.25days or a week !!!!
