Xantrex TRUEcharge3 20A 3-Bank 12V Battery Charger

The Xantrex TRUEcharge3 is a 20A three-bank 12V charger with power factor correction and universal 90-265VAC input.

Twenty amps is the smallest TRUEcharge3, and across three banks that works out to modest current per bank. It suits maintaining a starting battery, a small house bank and an auxiliary rather than recovering large capacity. The 40A and 60A models cover boats where the banks are worked.

Lithium-ion is among the selectable profiles, which is worth noting on the smallest charger in a range. Some manufacturers reserve lithium support for their larger units, and a small boat converting to lithium then needs a bigger charger than the bank actually justifies.

Two-stage or three-stage charging is selectable, with equalization available for supported chemistries and recovery of deeply discharged batteries. Universal 90-265VAC input across 47-63Hz handles international shore power and variable generators, in a drip-resistant enclosure with reverse polarity protection.
