Time has come for a new battery for my 76. What can you recommend in the +\- $200 range?
The car will be driven 3-4 times a week around town. The new technology Is amazing but does it apply to a 45 year old car? Thanks! |

Be cautious if considering an Antigravity battery. It may or may not work for you.
In the thread, > What's your volt meter reading when cruising around town?, member raynekat, bought a 30 amp hr Antigravity and had issues with the battery supplying enough current with headlights, fogs, wipers, etc running. His discussions with Superhawk996 are really worth reading - before spending a lot of money on a lithium battery. I will be installing seat heaters so I know I will have extra current draw above what is standard. I was contemplating trying the Antigravity unit until I read the thread and opted instead for the Odyssey PC1200 (ODS-AGM42L). The Optima was second on my list. Thanks to these guys I think I avoided making the wrong choice. (IMG:style_emoticons/default/pray.gif) |

(IMG:style_emoticons/default/pray.gif) So, following up, I wonder if the issues that 911 people aren't running into with Anti-Gravity batteries but @raynekat did run into is related to the 914 battery being in a hot engine bay? From https://www.exploringoverland.com/overland-...-worth-the-cost Most lithium automotive batteries, including the Antigravity unit, can be used (i.e. discharged) at temperatures down to -20ºC (-4ºF). However, they cannot be charged at temperatures lower than about 0ºC (32ºF)… Keep in mind that these critical numbers represent the internal temperature of the battery, not the ambient air temperature… Fortunately, each Antigravity battery incorporates a sophisticated battery management system (BMS), which prevents charging when the temperature drops too low… Very high temperatures can also affect LiFePO4 performance. The listed upper limit for discharging the Antigravity deep-cycle battery is 55ºC (131ºF). For this reason, some owners install their lithium “house” batteries inside the vehicle or camper rather than in the engine compartment. Have to imagine 131° F isn't all that unusual in the 914 engine bay, and I have mixed feelings about relocating the battery to the front of the car. |
