Please recommend a battery tender for a 2007 boxster
Hi,
I am going to garage my boxster soon. for the last few years I have been removing the battery but this has led to problems I wont get into. This year I plan to leave it in and get a battery tender. DO I have to get one from posrsche? Or are they available from Amazon ? Thanks |
C-TEK. If you like paying a lot of money, you can get one with "PORSCHE" on the front. Or, you can get the exact same one with "C-TEK" on the front for half the price. Remember, you want a battery tender and not just a charger. I've used my C-TEK for seven winters, using the cigarette lighter adapter. It works perfectly.

I use the battery tender junior by deltran. 25 bucks works like a charm and she fired right up in the spring.

I too use the CTEK and really like it. They make a special one for cold climates which is good for where I live.

I like my CTEK too.

I've been using the bt junior for years on many things. Just don't leave it plugged in on lithium batteries, once up to full, unplug and remove. Hook it up in a week or two or three, repeat as needed.

HI I thought the point of a battery tender is that you leave it plugged in and it charges as needed?? |

I've been using battery tender junior for several years and have been happy with it. It is probably > 8 years old so I should replace it soon. |

Ctek is tried and true as a reliable tender for lead acid batteries. Just plug it in and forget it until spring.
Only crazy motorsport types like me use 5 lb lithium batteries that require special care and feeding. ;) I don't recommend leaving them in your car at all for winterizing but rather remove and store separately. I have a NOCO battery charger maintainer designed to charge lead acid, AGM, and lithium, batteries with their specific needs. The trouble is, this is a very smart charger with microprocessor technology to sense your battery type and condition. In a power outage it may lose it's memory and software crash... no charging taking place at all. I like it but keep it in the garage where I keep a close eye on it. |
Ctek make a specific maintainer for Li batteries that works just like all their other, plug it in and forget about it.

My trickle charger of choice is the BatteryMinder brand. But I'm sure both Battery Minder and Battery Tender are the same. Living in Chicago I seldom dirve my Boxster in the winter, except for the nicest of sunny winter days with no salt on the road so I keep it on the charger ALL winter and actually most of the summer too. My batteries typically last 8 to 9 years in doing so.
I run the pigtail connection next to the drivers side windshield wiper shaft. It lays nicely in the molding and is mostly hidden from view. I wanted to make it easy to get to so I can easily plug it in after driving. I also have my motorcycle connected to a second BatteryMinder and I follow the same proceedure with it. It's orginal OEM battery is 7 years old and still starts the cycle without issue. |
