If you only need to charge a typical modern car battery, the chance of it being anywhere close to 200Ah is slim. More likely 100Ah is the upper end you will see (even for the RS6) and often much less.imacool wrote:Does it have to be CTEK MXS-10? From a brief look on their web pages the differences between MXS-7 and 10 are the temp sensor and maximum output current.
Is it worth to go for the top model if chances are that I will never be in the need of charging a 200mAh battery?
Anyway,thanks for the info on these chargers.
The MXS10 for most purposes will be overkill, but is certainly the daddy of the consumer range. If you have a motorhome and a JCB to look after as well it could be the wise choice of course! The plus side is it will charge a typical 70-100Ah battery a lot quicker than a lesser model. Keep in mind this is not much of a plus unless you intend on charging batteries from flat a lot and need to do it quickly though. Of course once you have a CTEK charger you will mostly be maintaining batteries, not charging them from flat. Negatives are the price and the charger may not be suitable for smaller batteries (motorbike for example).
I would say the MXS 5.0 will be every charger you ever need for keeping your car battery topped up (still not the lowest model you could choose for the job from the CTEK range). It will charge a 110Ah battery from flat and can maintain batteries up to 160Ah. If you go for this one make sure buy the "2014" model with the red mode button. The new MXS 5 has automatic temperature mode selection and has better support for AGM batteries (which you will find in most stop/start cars).
