Just got back from a two week trip for work to China, yep, car stone cold dead.

Simple enough to install a battery tender and plug her in during long trips, but does anybody have a model that is the easiest, cost effective, simple for our cars?

That can be found in the US market.

 

10 XF Premium,
There is a large thread on this issue within this forum. For myself, I use the CTEK 7000. It is very simple to use, comes with connectors and is not bulky. Can be found on Ebay.

Plenty around and as always it is your choice what you go for.

 

Deltran makes the original battery tender have used them on motorcycle for years Home page - Batterytender.com

 

CTEK is the best and simple to use. I also have the CTEK Mulit US 7002 along with the 3300 and 800. You can't go wrong with the 7002!

 

Another vote for CTEK.

My CTEK-XS7000 is an excellent and reliable piece of kit. It runs permanently attached to whichever car is parked up in the garage.

I have the "wall-wart" Battery Tender and a Schumacher Speed Charge. Both work well for me. The Battery Tender is smaller though.

 

I have used the following model with other cars (before I got the XF) with good results:
BatteryMINDer Charger/Maintainer/Desulfator — 1.3 Amp, 12 Volt, Model# 12117 | Battery Maintainers| Northern Tool + Equipment

 

+1 to Flyjag's VDC Electronics Battery Minder endorsement. I run a couple of those, one of their solar's on the S-type and an on-board on a couple of vehicles with plans to add a couple more.
