12v battery maintenance


Recommended Posts


Out of interest can you safely put a Ctek charger on the 2019 + Rav4 Hybrid?  (12v accessory voucher).

Extracted from the Toyota UK blog advice:

"If you have a 12V Battery trickle charger, or a solar panel charger, and are confident using them, then these are a good option to keep the Battery fully charged while the vehicle is stationary for a period of time."

According to the car care nut on YouTube

( he's a Toyota master tech) trickle charger should only be connected direct to 12v Battery,bit of a pain as it's in boot area .

I'm not entirely sure what you meant by "12v accessory voucher" but the 12v accessory sockets are live only when the ignition is 'on' so an attempt to use a charger while the ignition is 'off' will not be effective.

In the 4.5 there is a convenient jump start / trickle charge point under the bonnet which is much easier to access. I believe the same is true of the 4.4 hybrid.

Yes I'm aware of that 😏it's just he doesn't recommend using those for trickle charging ,not sure why .

The jump start point is clearly designed for, and man enough, for the job. All we are doing as part of the "jump start" procedure is toping-up the Battery sufficiently to get the electronics going. As you will know, there's no starter motor to turn over with the 12V system which is why the hybrid can get away with such a puny 12V Battery in the first place.

The owners manual states:

■ Before recharging:  When recharging, the 12-volt battery produces hydrogen gas which is flammable and explosive. Therefore, observe the following precautions before recharging:

  • If recharging with the 12-volt battery installed on the vehicle, be sure to disconnect the ground cable.
  • Make sure the power switch on the charger is off when connecting and disconnecting the charger cables to the 12-volt Battery.

There is clearly a risk of "over gassing" and a build-up of hydrogen in the boot area. But a good smart charger  will reduce any associated risk to a level that I am happy to live with. (The charging system built into in the car will charge the Battery in-situ in any case).

I wouldn't use an old fashioned 'dumb' charger and certainly not leave one connected for any length of time ...

When using the trickle charger you should also make sure that the charging current is less than 5A. This is normally stated on the top of your Battery pack (Panasonic OEM). Note that this is for the hybrid, I don't know if it is the same for non-hybrid.

I have a top of the range Ctek trickle charger that works on stop start cars etc, I forget the model number but I purchased it all year for my old car due to covid.

Probably CTEK MSX 5, though there are some other models, but I highly recommend that one.

I have hard wired a CETEK connector to the Battery under the boot floor, the connector is accessible now in the boot, so now just have to plug in the CETEK when needed.

I have been using this since March without problems.

Just had an email through from our dealer, Motorline Toyota Worcester, see below. I've spoken to them this morning and they're recommending the solar charger of which they have two types for £27 and £40 (forget capacities of these). The person I spoke to said he thought they could be connected via the cigar lighter socket. I'm going in on Monday morning to see what they have and how they recommend they are connected.

 

With most of us staying at home and being encouraged to park our cars if we can, you may be concerned about the level of charge in your batteries during long periods without use.

At Toyota, we like to give you total peace of mind. So we recommend buying a 12V Battery trickle charger or a solar panel charger to ensure your Battery remains fully charged at all times.

 

 
 
 
 
Which trickle charger is best for you?
 
 
 
 
 
Solar Powered
Solar-powered trickle chargers 
Solar-powered trickle chargers charge at a rate that's equal to the self-discharge rate, so they’ll keep your batteries charged at the proper level. They won’t charge a completely dead Battery, though.
 
 
 
 
Smart Battery
Smart Battery trickle chargers 
As well as discharging, analysing, conditioning and performing cycle tests on your batteries, smart trickle chargers typically charge your Battery in the same amount of time as a rapid charger.
