Now that's proper old school, lol! 

 

Is it worth changing from EFB to AGM?

Have a read bud.....

That's a bit 'agricultural' in appearance. Wouldn't leave that on overnight, just to be on the safe side. Probably won't need to anyway, looks like it'll charge fast.

That reads like AGM is better, being fitted to higher end cars as standard, whereas EFB seems to be fitted to the lower end of the market as standard?

It's my father in law's, he's been a mechanic for the last 40 or so years, he generally goes OTT on his tools. 

 

I'm going to leave it on charge until I go to bed tonight, then the Mrs is going to keep an eye on it whilst I'm at work tomorrow, then I'll try it on the car on Friday. 

 

Thanks for all the replies, much appreciated. 👍

@broona    I edited above, but it would not load..........It was re charging purposes. I think you will be ok with your charger but yes, as you say, keep an eye on it whilst charging. It seems like the efb batteries will accept faster charging than standard flooded batteries.

 

I was refering to what others had said re smart charger but it seems this only really needed for AGM batteries,

An automatic or a smart charger would still be safer tho imo. 

@Tilt, thanks for clarifying, I read earlier that EFB batteries are an enhanced version of standard batteries, and only AGM are a new technology, good to know. 

 

I might invest in a new smart charger at some point in time, see how this battery pans out first.

If you change it for the battery with the same capacity, I think you will not need coding. 

 

Wrong, the charger learns to charge a failing battery less, it will continue to do so (as batteries do not get better with age) until you tell the BCM it has a new battery by coding the serial number to a different number with at least 1 changed digit

I can hear the acid boiling from here 

 

Just remember to turn it off before you disconnect it from the battery, your eyebrows will thank me.

More than your eyebrows, a ruptured lead-acid battery is really no fun.

Okay and what's the real difference in charging? Just curious...

Although the 'regenerative' charging on these cars is not as fancy as it sounds it is still quite complex as it only loads the alternator when it is efficient to do so. The battery reserves and 'starting ability' are important to this working how it should. 

 

In simplistic terms it may be charging a lot more when it need not do and it may stop charging when it should. This will be wasting much of the point of a new battery and the shorter, more frequent charging cycles are not the best for a good battery.

 

You will also find it still protects the charge of what it thinks is a failing battery by stopping services (like KESSY etc) when standing, earlier than it would do if it knew it had a new battery.

 

Maybe it should sense a new battery, but I guess they assume people swapping the battery should know what they are doing

Battery charged for a few hours, refitted, car started perfectly, full lock both ways on the steering column to clear the errors, sorted, thanks for all the replies. 

 

Ordered one of these as I'm furloughed as of 7am Wednesday so the car will be standing even more - https://www.halfords.com/motoring/battery-maintenance/battery-accessories/ring-solar-power-240-battery-charger-196471.html
