Smart battery chargers
Any views/opinions on using 'smart' battery chargers ? My MR2 only gets used occasionally.
Do you have to disconnect the battery from the car ? If not, can you connect the smart charger to the cigarette lighter ?
Obviously I want to avoid the hassle of having to remove/replace the spare wheel & disconnect/reconnect the battery from the car.
Any advice greatly appreciated.

Re: Smart battery chargers
i believe its good practice to disconnect the battery, but i never have
as for cigarette lighter, its only live when the ignitions on iirc
just leave the spare out, i mean how many punctures have you had where you have had to use on ? and if you did get a puncture, would you be far from assistance ?
or you could wire in a solar charger, unsure on how but im sure Jimi has done it and will comment

Re: Smart battery chargers
you think its bad in an MR2, on the Seat i have , you have to remove the boot carpet, then loads of foam trays, then the wheel, then there is a cage around the battery with four bolts that needs to be removed, real pita
if you dont want to leave out the wheel, another suggestion is to hardwire a couple of leads to the battery terminals and route them around the spare wheel, you would need to ensure there well insulated when not in use though

Re: Smart battery chargers
Many thanks for the replies Jeff. Couple of years ago I added extra cables from the battery to route around the spare wheel. That's worked fine for me previously when using a normal charger but now having purchased a smart charger, the instructions clearly state it can be left switched on all the time but omits to state whether I should leave the battery connected to the car.

Re: Smart battery chargers
dont see how its much different to a normal charger, all it will do is switch to a maintenance charge when it detects the batteries fully charged

Re: Smart battery chargers
I'm using one of these smart chargers CTEK MXS 5.0 Fully Automatic Battery Charger (Charges, Maintains and Reconditions Car and Motorcycle Batteries) 12V, 5 Amp - UK Plug
And it can be hard wired to the battery with a clip on connection.

Re: Smart battery chargers
they look good, didn't realise they made them with a charging jack
wonder if you can purchase a spare set of jacks so you could use it on more than one car

Re: Smart battery chargers
CTEK, Optimate and a few other well known charges will sell you spare jack leads that you can leave connected to battery.
I use the same charger on the MR2 and my bike.
You don't need to disconnect the battery and you can leave charger connected till you want to use car / bike.

Re: Smart battery chargers
I've got several of the Lidl's smart chargers (£14), had them for years. Keep my
batteries up no problem. You have to go in store start of winter to get one though.
