What size battery charger???
Bought a 12v 18Amp battery to operate my mobility lift on the back of my truck.. Looking for a small battery charger to recharge the battery after 5 or 6 uses.... Have a big 12v charger for the garage...

What does 18 amp mean?
If it is the current drawn from the battery when in use, it needs to be multiplied by the time in hours it is in use per day to get the energy used in amp-hours. Then you could look for a charger that delivers that amount of energy in the time it will be charging the battery. If the charging time is ten times as long as the lifting time then the charger needs one tenth of the 18 amps.
