External battery charger
Now and again I use an external three stage battery charger on my two 6 volts without disconnecting the batteries from the trailer. I have not had any issues so far but was recently told not a good id...
Forum Discussion
Are we arguing over whether a charger can get a starting battery charged enough to start a vehicle, or whether it can indeed fully charge a deeply cycled battery?
Why not throw another variable into the mix and make the battery one which is still hooked to loads, perhaps cycling loads like a compressor fridge.
I've not doubt and charger can charge a battery enough to start an engine, I've huge doubts that when it drops to float mode, that the depleted starting marine/deepcycle battery battery is indeed fully charged, or anywhere near it in some cases.
Most of the public will only throw a charger on a starting battery when it has failed to start their engine, and such a battery needs absorption voltage to be held for longer, and the regular automatic smart charger is not going to do this, yet that green light will easily convince the user that it did, and because the engine started, it worked right?
On this forum many people know the key to keeping a lead acid battery happy is charging it until it is 100% charged, regularly.
Automatic chargers which can claim to do this, but cannot, are not doing anyone any favors, no matter how much faith one has in their purchase or the product's marketing, or how badly they want to believe the marketing, or how many people they can get to agree with their purchase/decision.
Perhaps such people's ancestors were the first to line up to listen to the snake oil salesman's pitch.
