Battery desulphation

[sjb993]

Does anyone have any experience of battery desulphators (e.g. F16 Pulse King)? If so, I'd appreciate your opinion on their usefulness.

TIA

I have a desulphation function in my ctek. Have used it on old batteries a few times and found that although it brings them back enough that they hold a charge the batteries are never very good afterwards and I have always ended up replacing with a new battery.

This...I've never found this to provide any meaningful extra life from a battery

Thanks for the replies.

I also have a CTEK charger and I'm aware that has a desulphation phase in its charging cycle. What I am wondering is, whether rather than using a charger to recover a battery, having a desulphator permanently attached to the battery is beneficial. That is, prevention is better than a cure.

The desulphation phase is only a few minutes, if I recall correctly.

On a healthy battery leave your ctek permanently (or at least regularly) attached and powered to avoid any such issues.

I have now binned my third ctek charger. Not economical to repair. I will consider other brands when I replace it.

Thanks.

There is a steady build-up of lead sulphate crystals on battery plates which degrade the battery over time. Using a charger is only a periodic event, and so the lead sulphate crystals won’t be removed from the plates very frequently. A desulphator that is permanently attached to the battery, and thereby prevents any build-up, would seem to be beneficial.

I am interested to find out if there are any downsides with desulphators.

What how?


I have one been wired up in a motorhome for the last 8 years and never had an issue with it other then having to reset if if the battery's has been disconnected




...


Also battery only really get sulphation in the plates being being sat for periods of time without sufficient charge

I have a race car and a Transit "race truck". On both I have CTEK MSX5s, set to "Maintain", because they are used approx. monthly in the season
Both batteries seem to be in good health after several years.

Dunno. Just bad luck I suppose. I have 6 (I think) and 3 have failed. The 25 amp version cost a lot of money and the PCB blew.
