Frequently asked questions
Can I charge it with a lithium (Li-ion) charger?
No. Lead-acid batteries need a charger that matches the lead-acid voltage and charge profile. Lithium chargers are unsuitable and can damage the battery or create a safety hazard. Use a 4V lead-acid charger or a regulated constant-voltage source with current limiting.
Should I recharge it soon after use?
Yes. Lead-acid batteries degrade when left in a deeply discharged state, so recharge them soon after use to extend their service life.
