Battery Chargers & Maintainers for Lead-Acid Batteries
For maximum life, charge lead-acid batteries at approximately 10% of their amp-hour rating. For example, a 17 amp-hour battery should be charged at a setting close to 1.7 amps (1.5 or 2 amps would be ideal). A higher setting can be used on occasion for emergencies, but repeatedly doing so will shorten battery life.
Note: All of the chargers and tenders shown here are compatible with any lead-acid battery we carry. Lithium-based batteries require a different type of charger.
