Battery Myth | Will a Small Charger Maintain a Large Bank of Batteries?

Posted on January 17, 2011
Quick answer: No. When you are dealing with a bank of batteries that is collectively larger than a car battery (max 100 amp/hours), you should crunch the numbers to find the ideal charger for your situation. Normal, static power drain on a brand new battery can be as high as 2-3% a month, which in the case of a 1000 amp battery pack(total)would translate to roughly 30 amps. Assuming the batteries are hooked up to something, it would be fair to double that. If your batteries are not new, the drain will likely be even more. So triple that number. If we assume a total 10% monthly drain, in this case 100 amps, you can see that you are tasking a small battery charger to recharge the same amount of power normally reserved for a larger charger. read more...

Example: you have a 12v water pump that takes 1 amp per hour and you want to run it for 2 hours a day which would equal 2 amps a day. read more...
