Who has one? Have you managed to revive a knackered battery with it? If so what brand is your charger & price please?

Watched a fair few YouTube videos on refurbishing batteries im not entirely convinced by the Epsom salt method, but I  believe that by charging a battery hard it can desulphate the plates and you can actually buy battery chargers with a special feature for this..
Any recommendations appreciated.

I bought a brand new battery for my car before my accident and I made the stupid mistake of just letting it sit there for four months so that was a gonna & I have a couple of leisure batteries I managed to wreck after not a huge amount of time so if this works it could be a good thing.

Interesting - never heard of this - what is the cost to revive a battery ?

Sorry to hear about your accident.

Battery sulphation occurs when a battery is left flat for a long period of time. If the sulphation is new and 'soft' then higher voltage charging can help. But soft sulphation occurs with normal everyday battery use and charging removes it anyway. It's how a battery works. But once the sulphation has hardened on the plates its impossible to revive the battery.

If there is a mixture of hard and soft sulphate on the plates then a high charging voltage can help with the soft but not the hard. In many cases it could be just enough to revive the battery enough to start the engine. But the capacity of the battery will be reduced and probably won't last long.

Personally I wouldn't fork out for a battery charger that the manufacturers claim will do this. The C-Tek one is expensive and you have no guarantee that it will work. I would replace the batteries now.

If you have a sealed maintenance free battery it should never be recharged at a voltage higher than 14.2v due to gassing. Recharging it at 15 + volts isn't recommended.

Thanks Bruce, as you said in a lot of the YouTube videos old batteries were revived but could not hold anywhere near the capacity as when new.

Another method on YouTube people are draining the acid and replacing with deionised water with dissolved Epsom salts! 😱
Then charging for a couple of days again that's meant to help de-sulphating with varied results but probably only helps as a very temporary measure.

So perhaps the conclusion is.. read up on the maintenance of my batteries when I buy them and take better care of them 👍

Sometimes circumstances dictate that this isn't always possible. Many vehicles have been left standing idle for the past 4 months. Many leasing companies took back vehicles from business' that closed due to the shutdown. These vehicles will have stood idle with alarms and immobilisers slowly flattening the battery.

They will jump start most but there will be mega  battery sales in the next few months. Starter batteries will be the most effected and I would expect there to be a shortage.
Many motorhomes and caravan leisure batteries go flat during the winter and have to be replaced in Spring due to sulphation.

I have revived a few with Cteck chargers.

During the 5 weeks we locked down I went to the unit twice weekly to run the vans for 30 mins a time just to keep everything ticking over
