Furthermore, will a float charger charge a dead battery?

Float Chargers – Unlike trickle chargers, they don't charge batteries, they maintain them. Although they can't recharge a dead battery, they can be used frequently and left connected to a battery without any risk of overcharging. Float chargers automatically shut off when the battery is fully charged.

Also, how long does it take to charge a 12 volt battery at 1.5 amps? A 1.5 amp trickle charger can charge a 50% discharged small car battery (200-315 CCA or RC 40-60) in about 15 to 19 hours, a mid-sized battery (315-550 CCA or RC 60-85) in 19 to 25 hours, or a large car battery (550-1,000 CCA or RC 85-190) in 24 to 46 hours. Double these times if the battery is fully discharged.

how long does it take to charge a dead battery with a battery charger?

24 hours

Should I charge my battery at 2 or 10 amps?

Slow charging using 10 amp chargers or less is generally accepted to be better. This is because repeatedly fast-charging a car battery may lead to overcharging and will severely reduce its performance. The short answer: 10 amp chargers are generally preferable than 2 amp chargers.
