Battery Charging...
At what setting should I charge (with a Sears battery charger) a moderately
discharged 12 volt car battery? My battery charger has a 2-amp and 10-amp 12 volt setting. My battery discharges quite a lot on one of my very old cars (don't ask!!) and I recharge after every 2 or 3 times driven. If I should use the 2-amp option, then what is the 10-amp setting ever used for? Comments? Thanks. EW |

Use the 10 amp setting for your car battery. The 2 amp is good for
motorcycle, ATV or electric start lawn mowers.

I thought the 2-amp setting would suffice, but will use the 10-amp option from now on. However, the 2-amp setting DOES fully charge the battery after several hours. Thanks. EW |

It will just take longer. A 100 mA solar charger also will fully charge the battery, it will just take 100 times longer than the 10A charger to get the same charge on the batter. --scott -- "C'est un Nagra.

Because with a manual charger the 10A setting could damage the battery after 1-2 days of use because the current will usually stay above 1-2A, even at full charge. OTOH automatic chargers contain an electronic regulator (you may be able to see a circuit board through the vent openings) that makes the current taper down to 1/2 A or less at full charge. If the battery discharges a lot, it might be better to recharge it after every trip, not after every 2-3. |
