Frequently Asked Question
Can I use my existing lead acid battery charger (standard, AGM or gel) to charge FRANCEBATTERY lithium iron phosphate batteries?
Last Updated 3 years ago
Most likely, yes. In general, lithium batteries are easy to charge. Most chargers today have a lithium charge profile, which we recommend using.
In most cases, AGM or gel charging profiles will work with our batteries. We do not recommend using a flooded charge profile with our batteries.
These chargers may reach the surge protection limit and disconnect.
This will not damage the battery, but will likely cause the charger to fail. Before using a charger with FRANCEBATTERY batteries, it is best to verify that the charging profile is within our specifications, which you can find in our charging instructions.
