Megawatt As A Battery Charger
- What separates the Megawatt from old fashioned transformer manual battery chargers is it's adjustable voltage
- All the difference in the world for safety and accuracy
- The missing control is a timer which is necessary and not hard to install
- Let's charge batteries!
- For flooded batteries on generator power I recommend 14.8 volts. Time limited. One discharged group 24 needs about 2 hours to charge
- Therefore 2 batteries would need 4 hours
- But that is not the best way to recharge when camping and you have an on board CONVERTER CHARGER. Let the converter charger do it's thing until it falls flat on it's face and starts charging at less than 40 amps
- Start the Megawatt to finish the charge
- Try one hour's time at 14.8 volts and see how the batteries like it
- You may need to tweak the time up or down for future charges
- For AGM set the Megawatt of 14.4 volts. When the onboard converter falls flat on it's face start the Megawatt. Let amperage slump to one half an amp for a 100 amp hour AGM, or one full amp for a pair of 100 amp hour AGM batteries
- Charging elapsed time shutoff is not as strict on AGM batteries as it is with flooded batteries
- If amperage drops to one half amp who cares? It can stay there for an extra one or three hours
- Getting a feel for timing a charge comes naturally. Cooking a 17 pound turkey versus an 11 pound turkey is harder to remember and deal with than tweaking battery charge times
- Unless a charger or converter allows the user to set the total time of the main charge it is not a charger, it is a toy. A pretender.
