JAC0348MAN – Schauer 48V, 2.5A Golf Cart Battery Maintainer – 115VAC – Battery Clips

Description

Model JAC0348MAN (0891-142)

Schauer JAC0348MAN – 48V, 2.5A Electronic Battery Maintainer with Battery Clips

Extend the life of your golf cart batteries with the Schauer JAC0348MAN Battery Maintainer. Simply connect it to your set of fully-charged batteries, and this maintainer will keep your batteries at full charge and prevent sulfation during periods of storage. The JAC0348MAN is designed to be connected to your batteries for extended periods, even months at a time – keeping them in peak condition and ready to go.

2-Stage Charge Control provides 2.5A bulk charge to a constant finishing voltage of 52.7V, then to a float mode, providing only the amperage necessary to maintain the batteries at a float voltage of 52.7, depending upon their condition.

FOR 48 VOLT GOLF CARTS ONLY. PLEASE CHECK YOUR CART VOLTAGE BEFORE ORDERING.

NOTE: The JAC0348MAN is a BATTERY MAINTAINER, NOT A BATTERY CHARGER. It will keep your fully-charged golf cart batteries at a proper maintenance voltage, but it WILL NOT recharge a set of discharged golf cart batteries.

Features

• For 48 VOLT battery systems ONLY. Use on 10AH to 300AH lead acid batteries – typical of golf carts, industrial scrubbers, etc.
• Can be used for any type lead acid battery, including conventional, maintenance free, deep cycle, gelled-type, valve regulated batteries.
• Current limiting
• Short Circuit and Reverse-Polarity protection (user-replaceable fuse)
• Fully automatic maintainer can be left on the battery in maintaining/float mode. If AC power is interrupted, the maintainer will turn itself back on when AC power is restored.
• Aluminum case with 2 LED status lights

The battery pack should first be fully charged with a primary charger. When primary charging is complete, remove the primary charger and connect the JAC0348MAN.

NOTE: THIS UNIT IS A BATTERY MAINTAINER, NOT A BATTERY CHARGER. IT WILL KEEP YOUR FULLY-CHARGED GOLF CART BATTERIES AT A PROPER MAINTENANCE VOLTAGE, BUT IT WILL NOT RECHARGE A SET OF DISCHARGED GOLF CART BATTERIES. If you use this unit on discharged golf cart batteries, damage to the unit will likely result, and the warranty will be voided.

Connection Sequence:
1) Attach positive (Red) battery clip to positive post of first battery in the series. (This post can be identified because it has a cable that does not connect to another battery. The cable from this post is connected to the positive side of the cart’s electrical system.)
2) Attach Negative (Black) battery clip to negative post of last battery in the series. (As with the positive post connection, this post can also be identified because it has a cable that does not connect to another battery. The cable from this post is connected to the negative side of the cart’s electrical system, or to a common ground.)
3) Plug maintainer into AC power.
4) Turn maintainer power switch on.
Use Caution! Incorrect connection across complete battery pack may cause battery over voltage/damage/fire/explosion.
NOTE: Since the maintainer is connected directly to the battery posts (and not charging through the golf cart system), the golf cart may be put in “tow” mode to avoid any load on the batteries while in maintenance.

The JAC0348MAN maintainer will provide 2.5 amp charging current until the battery voltage reaches 52.7V. Then it will hold float voltage at 52.7V and only provide the amount of current necessary to maintain the batteries at 52.7V, depending upon their condition. If the battery voltage is below 52.7V when the maintainer is connected, then it will cycle through this process.

LED Status Indicator Lights in normal charge cycle:
• LED 1 (Left): RED – AC Power connected, Power Switch ON
• LED 2 (Right): OFF – Battery not connected / Fuse Blown
• LED 2 (Right): YELLOW – High Current mode – 2.5-0.5A output. Fan: HIGH
• LED 2 (Right): GREEN – Low Current mode – ≤1A output. Fan: OFF
