12v Battery charger???

[DN22 Gardening]

Best one we've bought is a little £14.99 one from Wilko's.

 

Stick it on anything overnight and its charged the next day.

 

We've also got a big Clark Charge and start that was £200+ thats good for firing anything up immediately. Also charges 6v, 12v, and 24v.

Lidl or Aldi occasionally sell a Tronic 3.6A intelligent charger for 10 quid which is good for all but the profoundly dead batteries.

 

It is protected against overheating, wrong polarity and over charging.

 

It has settings for gellcells, motorcycle and car batteries as well as a winter setting.

Are these avaliable on ebay?

Optimum charge rate for a battery is a tenth of it's capacity, prolonged charging at anything greater runs the risk of shortening the life of the battery.

 

So a 50 Ah battery would ideally get 5 amps for 10 hours, 20 Ah would get 2 amps, etc.

 

Anything totally discharged for any length of time will need a charger with a "de-sulphating" setting to have any chance of bringing it back to life

They are reputedly rebranded CTEK ones that cost over £40 on ebay.

 

They look like this:

 

 

Once they are connected you cycle through the functions by pressing the left hand button. When it is charging a red led is on and green lights when charged. It is safe to leave it on all the time but you are advised not to charge when the battery is connected to vehicle, in practice I have had no problem doing it in a vehicle.

Similar to the Opimate I used on my bike .

I had a ctek xs25000 which is a big charger but it cooked a couple of batteries, it said from 40-500 amp but it was way too powerful, so I bought a ctek xs7000 which has been a fantastic little charger, charges any big batteries overnight.
