I have quite a few of these battery filler bottles for sale. Brand new - never used. They have a spring loaded valve, narrow opening and wide seat for easy stable control while filling from the sure grip handle. Nozzle design prevents spillage - liquid only flows when you push down on the spout and stops flowing when the cell has reached proper level, no overfilling. Features double-action fast flow valve tip to prevent after drip. Stops surface discharge from wet battery surface and contamination of electrolyte from dirty battery surfaces. Safe to use with battery acid. I also have fully automatic 48v chargers available. DO NOT contact me with any other offers or "help" selling anything, not interested in trades, CASH ONLY. If the ad's still up, there's at least one still available. I'll end the ad when they're all gone.
