General comment again on capacity exemplified here, this one is 60Ah pbeq, lead equivalent, so probably only actual 20Ah capacity (or bit lower). Easy to be confused by this...

maybe, though the capacity is not full 60Ah what stated.. or I'm confused how these are calculated as the CS Batterie 20Ah capacity is 72Ah (PbEq) with that logic..
I think the difference is not just the recup, its the intelligent charging. Yaris does not have recup, but maybe intelligent charging?

I know nothing about batteries hense this question. I leave the GRY for a couple of weeks between use over winter and have remembered that I have a CTEK MXS 5.0 charger I bought about 6 years ago for Celica and will use it every now and again to keep the GRY topped up. It is the older version with the snow flake next to the car picture. The handbook says it will charge most AGM batteries.
What sort of battery is in my car as I can't see it saying AGM anywhere on it. It does say stop start.
The new CTEK charger says AGM as a mode rather than the snow flake for cold charging.
What does the AGM mode do that the normal car mode won't do on mine?
I am hoping that my older charger will still be OK for my battery as they are about £70 just to have that AGM mode on it.
Just bought and installed the comfort connector in the engine bay with the three LEDs and fuse and will charge it once every couple of months.

Have had car parked for a week now couple of times and so far zero issues in cranking so initial worries of having the sufficient charge after longer parking seems not to be a real issue.
Maybe if car was parked in cold weather (below -20’C) for weeks but that is not a propable use case.

I leave my car for 3 weeks quite often. Only had it go flat once when I left it 6 weeks.
My 2p on light batteries is that the rear left is the last place you want to remove weight from in a RHD car. When I cornerweighted mine it was really low. I actually keep a load of tools and spare fluids around the battery to make it heavier.

just short bump on this thread - working remotely and driving short distances, have had zero issues with the battery. Haven't recharged it for ages.
The standard GR Four battery is a wet battery, ie, not AGM, your existing charger should be fine.
When your vehicle is parked over time is alarm and immobiliser active or not ?

Interestingly, I stick the Optimate that I use on my bike and my Escort on the GR every now and again to prevent it going flat, as I don't use it over Winter. The Optimate lights its orange light first, (charging) then when fully charged, its green light. Now and again it drops into test and maintain mode, so orange on again, then green, and so on. However, on the GR (I connect directly to the battery terminals) it never goes green, always stays on orange, so there's definitely something unusual there.
same, so mine and your Lithium battery's last for months, be interesting know how long would last if alarm was active

... And parked outside, which winter time is a much tougher use case in at least the Nordic countries...
yes, especially as LiFePo does not charge under 0'C temperatures. Would not maybe use in nordics if car is always below zero temps. Especially as battery is not next to engine.
topped the LiFePo with charger - have been driving lots of short trips during this winter.
Charger showed 50% of charge for the battery.

Warmed the car up and drove few short trips. 2nd start all was good but 3rd was again reporting low.
