The battery on my 300C 3.0CRD Estate is showing signs of being past it's best before date.

I guess it is the original one from 2009 and its not holding its charge very well. Voltage after overnight rest is 12.1 volts falls to 10.9 - 11.1 volts when ignition is on and glow plugs heating.

I bought a Yuasa 5000 for the Jeep as at 100 Ah & 900 cca it was a good spec for the price with 5 year warranty.

Had a look on the Battery Megastore site and they show a Hankook 100 Ah 850 cca 4 yr warranty for £68.50 delivered anyone here tried this make ?

Decided against the Hankook battery and ordered one of these instead same money but its a Platin 12 Volts 105 Ah and 920 cca with 4 year warranty. (probably worthless)

Well the new battery arrived today and it's labelled up by the Manufacturer Platin as 105 Ah with a creditable 950 cca not the 930 cca as advertised. Makes me happier as they appear to have reduced the price from £69 to £51.76 for 24 hours !

This morning there was a heavy frost and despite the Chrysler being in the garage it struggled to crank over and start.

Sure does first the Jeep that stands outside had battery failure then the Chrysler that I always garage overnight started to struggle.

Mercedes is permanently on charge from the C-Tek in the winter, its an AGM technology battery that I put on her in the summer of 2014 the previous battery was on her in 2003 when we bought her so lasted 11 years plus.
