New battery advice 21 Yaris 1.5 HEV CVT

[Andyh72]

Hi, my parents have the above car and had to jump start it recently due to flat Battery. We know they need to run it more, but Toyota have suggested to have a 264 cca 35Ah Battery fitted, but to me this doesnt seem to be very powerful.

I have no idea on the spec of the current one but its the factory original.

Looking online have had quotes for ones up to 440cca 45Ah.

Whats the highest rating we can get and would any system reset be needed especially with increased power or is it a simple 1 out 1 in.

Thanks

You need to reset retune radio and from memory phone shortcut keys the rest loads in automaticly.

 Yuasa HSB202 Part no YBX5202  45AH cca 440 amps

 or use Varta blue dynamic   544 401 042 or B 36 44AH 440 amps are the most popular.

Hope this helps.

Maybe a good time to fit Battery Monitor look under BM Battery monitor and charging connectors for you prefered Battery charger or CTEK NOCO or others.
