A friend needs a battery charger to charge her motorhome and various other things from time to time, I said to make sure whatever charger she buys , to make sure it can charge a very flat battery (left lights on, totally flat for example) many modern chargers in my experience won't even recognise a battery being connected and won't start. Any recommendation for a charger (maybe 4 to 10 amps size) that will charge a flat battery? I have a proper old skool 1980s charger with an analogue ammeter but I doubt you can buy this type anymore.

i think most chargers have a setting to just give out a low starting current for when the battery is well dead.

Old school transformer charger, usually picked up at boot sales for a couple of quid.

I've got this one now that the very old one from Aldi has died. www.halfords.com/motoring/battery-maintenance/battery-chargers/halfords-advanced-workshop-12a-smart-charger-191179.htmlI used to link two batteries together to trick the Aldi one into thinking a flat battery was greater than 6v... I'm 99% certain my new charger didn't need that effort the other week. I was rushing so didn't take too much notice. It might be a bit too pricey and have too many features for some though. If your friend has a camper but uses the single vehicle battery, investing in a leisure battery and split charge relay may be a better idea. |

It has a leisure battery also.
Yes thats another problem with 'smart' chargers, they try to auto select 6 volt.

I have a CTEK CT5, great charger/maintainer but it needs a minimum battery voltage of 2.0v or it won't start charging, AFAIK all CTECK's are the same.
