Battery Tender Power Tender 5 A – Fast Charging and Smart Maintenance for 12V and 6V Batteries
The Power Tender 5 A 12V/6V is the most powerful dual-voltage multi-chemistry charger in the standard Battery Tender range. It delivers 5 amps of smart charging for both 6V and 12V batteries, whether lead-acid or lithium. Thanks to its 4-step charging process (initialization, bulk, absorption, float), it recharges large automotive and marine batteries up to four times faster than a 1.25 A charger, then automatically switches to maintenance mode to extend battery life. Automatic temperature compensation, spark-proof and reverse polarity protection, weather-resistant casing.
