“Resurrection – It Is Able To Awake A Really Very Dead Battery”

I attached my cheepo float charger to keep my 74 Honda CB360 battery. OOPS! Three weeks afterwards not only is that the battery dead, also 2 of the cells are BONE dry. I put in water that is distilled to raise the flooded wet cell liquid amount that is 12Amp to midpoint between the lines at the very top. I attached a Fluke voltmeter and watched 3 volts – 50 or so for a fresh battery. I thought of my G3500 V2 (with fix) and thought why not. To my surprise it started to charge – took a mighty long time – about 14 hours on low setting. Next I ran repair till a green light (approximately 4 hours). As there was a few solids in the base of several cells, a marathon attempt was left by me. I alternated between repair and low charge for three times, slowly as the bubbles rose; the solids dissolved and the base cleared. I was amazed. Would it begin the lengthy sitting cycle, and if so will the fee continue at least a week? YES to both!! Honestly, I was 99% on the way to simply ordering a new battery. I would but for the fact that my 74 bicycle has a kick starter. I am delighted with what the G3500 V2 did. A click on this was useful would be appreciated.

“Nice Small Unit. So Far So Good. ”

I’ve only used this charger and it did everything I expected it to. Build quality is good. Cables feel a little cheap but theyre OK. The alligator clamps didnt look like they had an extremely tight grip on the battery posts, but they didnt let go and provided enough contact for a appropriate charge.My 81 amp-hour Interstate 24M-XHD marine cranking battery took 11 hours to control. If you do the math I figure it makes sense: 81 amp-hours divided by 7.2 amp charger equals 11.25 hours to bill. Just be sure to allow lots of time to charge your vehicle battery. I wasnt in a rush, so it was no big thing. Ensure that you read the manual because this charger can accommodate many distinct kinds of batteries. You need to select the style that matches your battery type (i.e. wet cell, AGM, etc.) See my photos.UPDATE fourteen days later : I decided to top off the battery after leaving it disconnected for approximately fourteen days. The battery just took about 10 minutes to reach 100%. UPDATE April 2016: After my ship battery sat disconnected all winter in my garage (with temperatures occasionally down to -30 degrees F), I hooked up the charger on a mild spring afternoon. The battery reached 100 percent in under 60 seconds. So it essentially kept its charge all winter. I allow the battery charge for approximately 12 hours just to maintain it since I wont be starting the boat for a few more months.
