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 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.

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.
