Why 12V lithium batteries don’t accept 12V lead acid battery charger?

Why 12V lithium batteries don’t accept 12V lead acid battery charger?

 

Per lead acid manufacturer’s recommendation, lead acid battery charge volt is 14.4V.

Per 12V lithium batteries’/ 12V LiFePO4 batteries’ spec, battery charge volt is 14.4V too.

Why many 12V lithium batteries don’t accept 12V lead acid battery charger?

 

1, For many lead acid battery charger: higher current also means higher charge volt.

Per the battery charger’s spec:

20A battery charger, max volt is 14V.

50A battery charger, max volt is 18V.

If 12V lithium batteries without BMS, 50A charger may cause batteries on fire or explode.

2, For some cheap lead acid battery chargers, the charger’s PCB board is poor accuracy.

All lead acid battery charger have nominal tech data, but due to price competition, some cheap battery charger’s tech data is far from its nominal tech data.

For example: some battery charger’s charging volt is 14.4V, but it’s actually 14.4V±2V, charging volt varies from 16.4V-12.4V.

High charge volt will cause lithium battery’s safety issue.

 

3, Battery charger with RECOND mode

For some well-designed battery charger, it has different charging mode: such as Normal (14.4V), Supply (13.6V), and Recond (15.8V, 1.5A, 0.5-4 hours).

For the Recond mode, it may shorten the life of lighting system, and 12V lithium batteries definitely don’t like this mode, as it may cause safety issue.



As lead acid battery charger’s charging mode is hard to know, so 12V lithium battery manufacturer don’t like users to use lead acid battery charger, to prevent safety accidents.
