Battery Knowledge

Q. What do the abbreviations MF, GEL and AGM mean?
A. Gel, AGM, Vlies, MF, Calcium/Calcium and Hybrid are abbreviations for different types of lead-acid batteries.

Q. What do the abbreviations LiFePO4, Li-ion, Li-MnO2 and LiCoO2 mean?

A. LiFePO4, Li-ion, Li-MnO2 and LiCoO2 are abbreviations for different types of lithium batteries, that means there batteries using different cathode materials. Different batteries have different charging voltages.


Battery Charger Knowledge

Q. What charger should I choose?
A. It depends on the type of battery, the capacity of the battery, the application and how much you are prepared to spend. Just tell us your battery information, DANL battery charger engineer will recommend the most suitable charger for you or customized by your batteries and applications.

Q. Can I charge several batteries in parallel?
A. The charger has no problem whatsoever of charging or maintaining several batteries, as long as they are connected in parallel. The charger sees the parallel connected batteries as one large battery. The sum of the capacity has to be below the recommendation for your model. Please note that there could be a high current between batteries when they are connected together, i.e. use high quality wiring.

Q. Can you really connect and then forget about the charger?
A. That depends on your batteries state and charger's type. Danl lead-acid battery chargers have maintenance mode(floating mode), charger charges with very small current at this mode, so you can forget about the charger but not exceed 24 hours. If your battery is lithium type and without BMS system, please don't forget the charger.
