To accommodate changing regulatory requirements (see Methods), we did the first replicate with birds housed in isolators until 35 d of age, after which they were moved to floor until they were 11 wk old (Experiment 4a), and the second replicate with birds maintained in floor pens from 1 d of age until 7 wk of age (Experiment 4b).

Then use a battery isolator switch to use only the starter to start, then recharge it, then recharge the house battery from the alternator. (mechanics.stackexchange.com)
These problems are easily remedied with new universal polyurethane coil spring isolators by Energy Suspension, which outperform standard rubber ones. (carparts.com)
