Don't. If you really need to buy make not only a proper battery scan,but also a take a look at the battery pack. There are many garages out there who are fixing cheating gadgets to show high battery capacity , when in reality many cells are damaged beyond repair.

Yes there is a risk. What you can do is - source a car with clean and good records preferably Toyota maintained (don't go for the ones serviced at the nearby joint) then take it to Toyota and get it inspected including battery report etc.

This actually applies to other cars too not just hybrids.

Thank you all for the valuable feedback. It does appear as though in general everyone is rather not too convinced with the Aqua. 

 

Thanks for all feedback.

Hi Guys

Cana bybrid car function without the hybrid battery or is it entirely reliant on the battery? 

 

I know the Honda FD3 has been known to function without the hyrbid battery. 

 

Please let me know.

Both Toyota and Honda hybrids have direct link from the Engine to the gearbox although Honda is a Series and Toyotas are parallel hybrids(unlike newer hybrids like Nissan eNote where engine is used only to charge the battery)

So theoretically it should be possible to drive without battery,although you will get many errors and bad fuel consumption.

The Diagnostic system may however put the car in to a safety mode like "limp home" or even not allow to start the car at all. So you will need a cheating gadjet like already found in some 2nd hand Aquas, which makes the computer believe that the battery is functioning.

@gayanath may be you can help him find one from your side business? ?

Seems your "theoretically" means just two words "series and parallel". Otherwise, If you go through the construction of Toyota HSD or Honda DCT, you may note that, even theoretically it cannot be run without a battery. Motor is the main controlling part in GB so its nearly impossible to work with direct generator power rather than having a storage. 

Someone can suggest that, the system could be modified to run without a battery but buying a new car may cheaper than that.

Note: Sometimes, Nissan eNote may modify (not sure) easier than Toyota HSD or Honda DCT's to run without a battery. Then it will run just like a locomotive :laughing-smiley-002:

Battery as well as IMG wires will have to be disconnected or fixed to a "gadget" isn't it? Feel sorry about those who have no alternative but to bear the high cost of battery replacement now,especially those who bought second hand who were not even able to get the benefits of fuel savings like the first user.

This is not an aqua but a wagonR. So thought of sharing the experience of one my friends. 

It is a nearly three years old wagonR done over just 100k.  It started indicating that hybrid battery was no longer charging.  But vehicle was running as usual, no issue with starting,  pick up was OK.  Over couple of days time hybrid battery discharged to a very low value and all of a sudden car stalled.  Couldn't start at all.  Then he found both the batteries were dead. 

My guess was regular battery got exhausted in the absence of support from hybrid battery. 

Now you can guess what has happened.

The vehicle should be designed to work considering the power from Hi-voltage battery supplying the 12V system via DCDC converter.(Power steering,AC). And as per safety regulations, every Hybrid has to discharge the Hi-voltages remaining in the hybrid components(DC-link capacitor,Inverter..) after IG-off. Usually the Hi-voltage battery is used for this. If it is fully charged or not available, then it will try to discharge with 12V battery as a load via a dedicated FET-PTC discharge path.

So in both cases I think the 12V battery will get unnecessary stress and fail very often.

Its what happens . Problem is for these Hybrids you have to use specific batteries else the issues will get worse.  And I believe in WaganR there are few common problems such as tension-er , alternator getting issues ect..
