Hybrid 12V Battery drain issues


Recommended Posts

Going Through various posts one can see that the Hybrid has Battery drain issues once car parks for several days.

As an owner of 2019 Hybrid Corolla Limited I face this issue especially these days in which a lot of us do not commute to work (working from home)

I wonder  if Toyota did address this issue (software update???)

If not, how come this issue is not highly published   ???

Well the solutions are generally - Use the car more, Turn off the Smart/Keyless Entry system or Use a trickle charger or solar top-up charger.

I'd not used mine for 2 weeks and it still worked fine when I fired it back up, but I'd been using it regularly before that.

Most of the people having problems seem to have used the car infrequently, then left it for a long time, so the Battery never had much charge to begin with.

Thanks for the prompt response!

Can you please elaborate regarding " Turn off the Smart/Keyless Entry system" ?

  1.  Does this feature surges high idle current?
  2.  How much improvement one should expect by this action?
  3.  How Do I disable the Smart Key System?

It seems to be the system that draws the most power when the car is off; You can disable it via the headunit settings, but you'd have to check the manual for the exact steps.

Lockdown killed a lot of batteries, even new cars off the production line had borderline Battery issues

IIRC the corolla hybrid E210 uses a standard lead acid Battery, that are not that stupidly expensive for a quality item from the likes of Bosch (S4, S5), Varta or Yuasa - starting around 55 euros

Varta & Bosch automotive batteries are made by the same company.

I disagree slightly with Cyker but my profile leading to my last flat Battery was:

200 miles to airport - valet parking 4 miles - car moved - 16 days later 300 miles. 

Laid up for 11 days.  Battery showed steady voltage drop but between day 8, reasonable charge and day 11 down to less than 4v

Drive more, use Ready mode, trickle charge etc is just the way it goes.

Maybe so, not everywhere stocks both and prices can vary greatly depending on location/country and distribution

You can disagree with me - I mostly talk s**t anyway :laugh: 

TBH anything in a public forum should be considered more opinion than fact, esp. in the cesspool that the 'world wide web' has become!
