Bigger starter battery

[Adam H]

Hi all,

Got a 2019 T6, original battery and its been playing up for a while. Last few weeks its taking longer to crank, not much but enough to be slightly embarrasing if it churns away for 5-10 seconds before biting. It's got a fair bit running off of it now like trackers and alarms, along with Clayton DC to DC so I feel like it needs more crank power and just a bigger battery.

Whats a sensible increase in power that will slot in without having to reinvent the wheel for battery size ? I realise it will need to be coded in if the power changes etc.

I've been looking at one of these, but i think it might be too big in width ? S5 A13 Bosch AGM Car Battery 12V 95Ah Type 019 AGM S5A13

The 5/6 year old one currently in is below

Hi folks
I have a 2021 T6 and think the battery is on it's way out, as it doesn't hold it's charge very well.
I think it's the original battery.
I don't have a tracker fitted, but it does have a DC to DC Victron unit.
I've read the threads on changing it and coding etc, but whilst I've seen people swapping to a bigger battery like this one

S5 A13 Bosch AGM Car Battery 12V 95Ah Type 019 AGM S5A13​

I wondered why? since there also seems to be an 80Ah version which is a little cheaper, but still bigger than the 70Ah currently fitted.
Thanks in advance for the replies, or if someone can point me towards an existing thread ( I have searched)
