12V 3.3A car/motorcycle SLA battery chargers

Brief Introduction

3PA5015 is a new member of a family of professional chargers from GUDY. It represents today`s new technology for lead-acid type battery charging. 3PA5015R programmed four auto stages ( Ud-I-Uo-Up) charging process,It is designed for all kinds of 12V 2~90Ah lead-acid battery, such as SLA, AGM and Gel battery. Stage [Ud" desulfurating the battery through 20V pulse,When the battery recovered, stage [I" will give bulk current charging( 0.8A or 3.3A, defined by user, for 2~8Ah 0.8A is prefer, 12~90Ah should select 3.3A). Then, [Uo" stage is followed, the output voltage is fixed on 14.4V( 14.7V is for low temperature, <5℃); When the current declined to 0.4A;stage"Up" will turn on duty. At this stage, the battery is charged completely and the charger give some pulse to maintenance the battery.

Specification

*)The back current drain( reverse current ) is the current that the charger uses form the battery when the wall plug is not connected.

**)The ripple wave describes how many disturbances are exhibited by current and voltage. A rippled voltage can cause damage to other equipment connected to the battery.

How to use:

1. Connect positive charger clip (red) to positive battery terminal, the black clip to negative. (You can use other appendix wires to connect battery)

2. Connect the AC cord to the socket, The red alarm indication light will indicate a battery which is connected to reverse polarity.

3. Pressing the [MODE-button" and stepping forward one press at a time until the required mode is reached, the button is then release

4. When the [charging finished" led lights up, the battery is fully charged. When disconnecting charger, disconnect in reverse sequence from connecting procedure

The table shows the duration of the Bulk stepup to about 80% state of charge..
