I do try to drive my 914 all year, but it will have some down time when snow and salt are an issue.
"Finally" getting a battery tender. question: when hooking up the charger, is it safer or good practice to disconnect the ground? I have a switch, so easy enough to do..... |

QUOTE(Steve @ Dec 16 2021, 10:10 AM)  When I had an optima battery, I had to trickle charge it or it would be dead if the car sat for a week. I hard wired the cigarette lighter with a fuse to the battery. This made it easy to plug the trickle charger into the cigarette lighter. Since switching to an AGM battery, i no longer need the trickle charge. But recently I bought another 914 with an optima battery. This one has the battery in the front trunk, so I just wired the included plug to the battery. @Steve … Optimas are AGM batteries, no? Or am I confused? |

You're correct, I saw this as well, an Optima is an AGM battery. More likely the battery was on it's last legs and a small drain (like a clock radio) and the new battery fixed the issue. |

Correct, the Optima battery in my 3.2 914 was well over 10 years old. Now that we have other AGM battery options in the stock size, I just replaced it. Nothing changed on the car, but it still starts after two weeks or more of sitting. The yellow optima battery in the v8 914 i just bought also dies after one week of sitting, but it did have lighted electric window buttons that went directly to the battery and were on all the time. I wired up an accessory toggle switch, so I can shut it off when I'm not driving it. We shall see if it still dies. |
