6V 3AH Sealed Lead Acid Charger
This compact charger is built for 6V and 12V sealed lead acid batteries up to 3AH capacity. It suits owners of motorcycles, scooters, ride-on toys and small backup power systems who need reliable maintenance charging. The automatic three-stage logic handles bulk, absorption and float phases without user intervention.
Automatic 100-240V AC Input Operation
The unit accepts worldwide mains voltage from 100 to 240V AC at 50 to 60Hz drawing 1.0A. It delivers selectable 6V or 12V DC output at a constant 3.0A current before switching to float voltages of 6.7 to 6.9V or 13.5 to 13.8V respectively. Its 120.0 x 60.0 x 38.0mm footprint fits easily on a workbench or shelf.
LED Status Indication and Safety Protections
A two-colour LED shows red during charging and green when the battery reaches full charge. Built-in safeguards include short-circuit protection, reverse polarity protection and over-voltage protection. The package includes a single charger unit backed by a two-year free replacement warranty.

Questions about this item
Does the 3.0 A constant-current mode keep running indefinitely or does it taper off as the battery fills?
The charger moves through three stages — 3.0 A constant current, then 7.2 V to 7.4 V constant voltage for 6 V batteries, then 6.7 V to 6.9 V float — and shuts off automatically when the green LED shows full charge.
How much heat or noise does the unit produce when left plugged in all day?
No fan is fitted; the sealed case relies on passive cooling, so it runs silently and stays warm but not hot during continuous operation.
What must I already have to use this charger with a 6 V battery?
You need a 6 V sealed lead-acid battery and a mains supply of 100 V to 240 V AC at 50 Hz or 60 Hz; the charger connects directly to the battery terminals.
