If you are just trying to start the engine use 2 --12 volt batteries connected in parallel----same 12 V voltage BUT you get double the amperage----will really turn over the starter but not burn up sensitive equipment because of excess voltage--- charge with your regular charger ---best to NOT use a digital charger use the "old style" with the gauge---you can monitor the charging rate better and always use the lowest charge rate to avoid surface charging them--trickle charge with a float capability works great---good clean tight connections are a must as well as properly sized cable and GOOD grounds- We used 2 Braille's --FED 387
