What to Check Before Buying a Battery Charger
Before purchasing a battery charger, verify the battery type and voltage you need to charge. Keter chargers only work with Keter 20V MAX lithium-ion batteries, while Ironton chargers work with standard lead-acid batteries. Check the charging rate: a higher amperage means faster charging but may generate more heat. Also consider the charger's safety features, especially reverse polarity protection for automotive use.
Mistakes to Avoid When Choosing a Battery Charger
A common mistake is buying a charger that is incompatible with your battery chemistry. Keter chargers will not charge lead-acid batteries, and Ironton chargers will not charge lithium-ion batteries. Another error is overlooking the charging cable length; a short cable can be inconvenient in a workshop. Finally, don't ignore warranty terms: Keter offers 3 years, while Ironton offers only 1 year.
