Trickle charging the 12V battery in a Yaris Hybrid

[Prabhulal Shah]

I am starting my hybrid with a booster pack. I the Battery does not seem to retain the charge. I have old Battery cherger which I used to charge the normal Battery in petrol cars. Can I connect this charger to the under the fuse box + red point and negative on the car body to charge Yaris Hybrid 12V battery  slowly.   How much would a new 12V battery for Yaris Hybrid cost ?

It is not advisable to use an ordinary Battery charger.  Much better and safer to use a smart charger.  It is an expense but you can use it on a new Battery if you need to get a new Battery.

When you say it does not hold a charge, how much driving do you do after jump starting?

How often have you found the battery to be flat?  If it has been flat several times then a new battery might be the best option now.

Looks like the car is a 2015, so Battery could be at least 7 years old; if original then probably due for a change.

Cheap Battery approx £60, upper price £150

A Google search will bring up suppliers (Halfords, RAC, etc etc) where you put your reg in and it will list the options or your local dealer.

Please note its a diffrent type of Battery to those used in 2020 Yaris MK 4 cars.

I little tip for those not in the know, if you look on top of the Battery terminals you will see the date the Battery was made stamped on one of them. 

Edit to add - I didn't notice this is a hybrid my tip is for an ICE car but still may apply.
