accumate - how long?

[blackiepaul]

Hello all,

How long does it take for a accumate to charge a battery from flat?

Thanks for your help.

In my experience it'll never do it properly.

Accumates are completely pants at desulphating, they are little more than trickle chargers/ very weak conditioners.

If your battery is dead I wonder connect a heavy duty charger to it disconnected from the car. Good overnight charge and then keep it happy with the accumate.

If that's the Accumate trickle charger/battery conditioner it will take several days if it succeeds at all. I got one battery back from the dead but killed another that I had to replace.

Accumates are not really built for this purpose, ususally takes about 3-5 days or so from fully flat for a TVR sized battery. My Merc AMG took well over a week at that wasn't even flat.

I still swear by them though, perfect for garage queens

I put it on yesterday at 2:00 and wanted to put it back in the car today about 2:00. I will then use another car hooked up through the anderson plug to try to help start it.

What are my chances?

As mentioned they're just intended to cycle a battery on a car that's not being used on a regular basis.

I stick mine on my car when I go on holiday, that said I recharged a battery off my 406 that was totally flat and it took about 4-5 days iirc. The battery then went on to provide good service till I disposed of the car 18 months later.

There's a chance you might be able to jump start the thing....as to whether the battery will hold charge after being deep discharged is 50/50 in my experience.

We hooked it up yesterday through the anderson with a totally flat battery and it tried to turn over, I was hoping that 24 hours Trickle charge along with a jump start then a short run back to mine and then back on the accumate to charge again?

As as been said it all depends on just *how* flat your battery was/is but I reckon you stand a reasonable chance as long as you don't 'overcrank' it to get the car started otherwise you'll do damage to the actual structure of the battery, which may have already been damaged by being flattened.

Been in a garage for 5 months with out turning over

Absolutely no chance, IMO. You will be needing a new battery.

Yep +1 I have found once the battery has gone flat, you may get it working again for a very short while before it dies. Save yourself a load of time and effort and just bung a new one on

+2 I'd bung a new one in and just charge the other one with the accumate as an experiment and maybe keep it charged for an emergency if it still holds a charge.

Your battery may well be US now but re the de-sulphating - I think the CTEK conditioner may apparently do something about that as it doesn't merely top up until the battery is charged but also cycles/pulses during part of the charge which is supposed to help with de-sulphating. Whether it will recover a completely dead battery I'm not sure though.

[blackiepaul]

will have a new one by close of play today, just to be safe.

Thanks all.

Thing is I used to get all pissed off about dead batteries but to be honest they now cost about the same as a tank of petrol!

Unless you get the lightweight GT3 Porsche one.

Then it costs an arm, leg and left testicle.

Subtle as ever don :-)

5 months and 5 days. New Battery in, one flick of the ignition and it fired no problem at all, shame the engine comes ou in the next couple of weeks!

Thanks for your advice.

Remember to use your Accumate to preserve this battery...
