It is in the Main Fuse box. That's the one behind the battery (but not the one on the battery) on the right side of the car on top of the shock tower. There are two 50-Amp fuses in it. It is the one at the bottom of the U-shaped box.
Handle a "What"?
No, a 2 amp battery charger has a higher charging capacity than a 1 amp battery charger. This means the 2 amp charger can charge a battery faster than the 1 amp charger. It's important to use the appropriate charger to avoid damaging the battery.
may be you have the wrong battery, may be the battery is good with size, and amps, but some models have the connection on the inverse side where you need, then you must to look fot other battery with same size and amp. but with the connection on your right side, I hope this can help you
The 50 amp charging circuit will never be able achieve a full charge for the 70 amp hour battery, thus in effect turning the 70 amp hour battery into a 50 amp hour battery.
The maximum amp rating for a device designed to handle a 10-2 amp rating is 10 amps.
When charging a car battery, the choice between 2 amp and 6 amp depends on the battery's condition and the charging speed you desire. A 2 amp charger is better for maintaining battery health and is suitable for trickle charging or when you have more time, while a 6 amp charger will charge the battery faster but may generate more heat and could be less gentle on the battery. For optimal results, refer to the battery manufacturer's recommendations.
The typical amp hour rating of a marine battery is usually between 50 to 200 amp hours.
4 amp battery, some can fit up to a 7 amp.
my 1992 golf does this... it was due to the new amp and stereo :) fit a spare in the boot solved my problem
