That explains why my bike has great big cooling intakes under the seat then.





Lets face it, motorcycles have been using AGM batteries way before they were commonly available for cars and these fancy micro-processor controlled chargers.
You just went out and bought a battery charger suitable for a bike.
The same thing, but had a lower charging amperage.

My CAR MECHANICS mag arrived today and coincidently featured a CTEK MXS 10 charger, which they say has a RRP of £129.99. Sure enough, everyone is advertising it at £129.99, even Halfords.
Everyone except ECP who say it should be £300.60, less 15% makes it £254.00, and then apply code LOVE50 which when you apply it makes the grand total £249.89.

I don't usually criticise ECP (I often use them) but come on. You can see why they sometimes having a reputation for bumping prices up before supposedly discounting them.

I think the best time to get good prices from ECP is when they DO NOT have a 50% off sale!

My £12.99 Aldi charger is currently charging my ZTT which wouldn’t start this morning, showed 12.1v when first connected, car wouldn’t crank. I think the battery is on its last legs, no idea on its age, is at least 2 owners old! Will report back on the charger but you can choose trickle or full charging mode 0.8A or 3.8A. Also has an indicator to tell you charge level and voltage and auto detects 12v or 6v batteries. So far so good!

I agree with every word you say.
The debate is how suitable is the charger for AGM and EFB batteries.
Some people are wondering if it really can do the same job as products costing up to ten times more.
I admit I am undecided even though I have bought one. I am not concerned with it's capabilities on conventional car batteries.

Would you recommend that someone uses their 1970's 8A simple "Lead Acid Battery Charger" on an "Lead acid AGM battery"?

I would hope not!

I'd never recommend to charge any lead acid (or derivative technology battery) at 8A except in outright emergency. That sort of sustained charging current is liable to overheat almost any modern car or bike battery. Maybe some truck (or submarine) batteries or specialist power bank (thinking solar powwer) types are designed with plates large enough to take that but not your common or garden modern automotive battery.

Some people may be wondering if the 10x price is at all justifiable for what is, in essence a glorified 12v power supply. Given that high charging current is ruled out for the type of battery we are talking about. Looking at the materials that go into it (the bill of materials) and wholesale component prices then I can safely say that the price isn't justified, and that the markup is extraordinarily high for modern electronics.



I think also that if someone is spending £300 on a battery for a 75 or ZT then that's their call. The last new battery I bought (for the 1.8) was below £80 for a quality Bosch battery.

My concern with the cheap items - which are cheap for a reason which is that they use cheap components and have not invested in RD&D - is the integrity of car's electronics in the case of failures rather than the battery. I consider batteries to be consumable/scarificial items and never hesitate to change a battery.

As I said earlier, compare the lifespan of Infenion MOSFETS and other semiconductor components with their copies or equivalents from certain parts of the world, then the price differences, and you will soon know a) why the some chargers can be purchased for circa £15 and b) why others cost circa £60.

The LIDL and ALDI chargers are very good value, in that they are equivalent to £20 chargers but are sold for £13. If you are happy with such a device, great.

But, always ask yourself, with a modern car's electronics worth £5k to £20k, is the difference between £13 and £60 material?

As it happens, I bought my third CTEK 2 weeks ago - a MSX 5.0. So now I have 3* CTEK, 1* Optimate and 1* LIDL plus a traditional non-auto 4A/8A Halfords device. The CTEK is worth every penny when you look at it's design, construction and quality of materials.

Maninder, you've just cited the reason for existence of that wonderful new fangled invention that's taking the world by storm. It's called a fuse. You can buy one for £320, which is sure to be of a vastly higher quality than the 20p ones that are sold in motor factors

And guess how many of the cheap chargers do not have one! Also, if it does, can you trust it to act like a fuse?

Similarly, the cheap £2.89 DVM's. They are OK for simple tasks, but they are no Fluke 77!

Ditto cheap PC power supplies which are the closest item to a modern charger in terms of functionality. Many of them are dangerous!
