'''Introduction'''<br>
Alternator deletes have been shown to increase fuel economy as much as 10%. However, extra deep-cycle batteries (and/or another form of power) must be used as a replacement, and their cost may offset any economic savings of reduced fuel consumption.

That said, if your regular starting battery is in need of replacement anyway, it could be replaced with a good deep-cycle battery for not too much more money.

== Instructions for mod ==
Remove your alternator belt.

Note: you will need some other method of charging your battery for your car to work properly. Such as solar panels and/or externally powered battery charger.

- Deep cycle batteries can take 50% discharge <br>
- Lithium batteries can take an 80% discharge <br>
- Car may stall out while driving without energy to fire injectors, spark and run fuel pump<br>
- Some ecomodders have found poor car performance when the alternator is disconnected due to the lower voltage of the battery when the alternator is running
