EZ Battery ReconditioningBoth the OPTIMA Chargers Digital 400 and Digital 1200 12V Performance Battery Charger and Maintainer enhance the performance of OPTIMA and other AGM batteries, recover deeply discharged batteries and extend battery life. My opinion is that if new batteries cannot be designed to compensate for the heavy parasitic drain then the manufactures need to install two parallel batteries or come up with procedures to connect an external battery trickle changer when the car is parked overnight.
If your car's battery isn't holding a charge or otherwise is not up to par, you may be able to fix it. The most common cause of degraded battery performance in lead-acid batteries is sulfation, which occurs when sulfur collects on the lead plates in the battery, blocking the electric current.
Although the EBL's notification lights don't change color like the Panasonic's do, they still convey much of the same information—a flashing green light above one of the battery slots means the battery is dead or partially charged, and a solid green light means it's fully charged.
However, in terms of the total cost of ownership, including the likely dramatic reduction in battery life resulting from using a trickle charger, then the answer is ABSOLUTELY NO. The Battery Tender® Plus will more than make up the difference in price by extending the useful life of only one engine start battery.
The temperature compensation ratio employed by the Deltran Battery Tender Plus battery chargers is approximately minus 3.67 millivolts per battery cell per degree Centigrade of temperature rise above 25 °C. Stated easy and fast battery refurbishing guide another way, the output voltage of the Deltran Battery Tender Plus battery charger will drop 0.022 volts, or 22 millivolts, for every degree Centigrade temperature rise, when it is connected to a 12-volt battery.
With no answers I decided to drain the batteries of two scooters by running the motors with the throttle on full and turning the lights on. However after 5 hours of constant running the scooters meters were still showing full and the volts where at 48.7 and my volt meter was showing 48.6 volts.
Most deep-cycle applications have some sort of charging system already installed for battery charging (e.g. solar panels, inverter, golf car charger, alternator, etc.). However, there are still systems with deep-cycle batteries where an individual charger must be selected.
Batteries can be very dangerous if handled incorrectly, especially if you don't have the right safety equipment on. It's vital that you wear glasses and gloves to ensure that the battery acid doesn't leak out and burn your skin or anything else that it comes in contact with.
