Operation

• Not intended for use as a DC power supply
• Operate in an environment with proper ventilation
• Do not operate in a damp or wet environment

LED Status Indicator Light in normal charge cycle:
• LED1 (Left): RED – AC power connected, Power Switch ON
• LED2 (Right): YELLOW – Charging, Bulk and Absorption stages - Fan On
• LED2 (Right): GREEN – Battery Charged, Charger in Maintenance Float mode - Fan Off

NOTE: If LED2 is GREEN when initially connected to a known discharged battery (rather than YELLOW, which indicates normal operation), there is a FAULT in the output connection. Check for the following conditions:
1. Charger Not Connected
2. Minimum Battery Voltage Not Sensed (12V minimum)
3. Output Fuse Blown (check the fuse under the twist cap)

NOTE: PLP Battery Supply recommends that chargers in this range have an amperage output that equates to a minimum of approximately 10-15% the AH capacity of the battery being charged. For example, this 4 amp charger would be appropriate for a battery with a maximum AH capacity of 40AH. Chargers with marginally low output ratings may result in unacceptably long battery charge times and/or damage to the charger.

Would it kill them to put in a manual? Huh?
Color: Brown/Green/Tan
This review is tentative. Good: Attractive, and less cheap looking than expected Indiglo. Enough said. Analog is legible. Decent water resistance. Nostalgic for '80s ana-digi display?? This is no Chronosport, but the layout is nice. Seems accurate so far, but quartz watches mostly are. Bad: Non intuitive setting with no manual. It's frustrating so far. Not entirely sure what the features are at this point. Can I get 24H same time zone digital sync'd w/ analog? FWIW: I replaced the strap immediately with a Maratac. Brown nylon, PVD buckle. Look perfect together, I'm chuffed. I want to like the watch, but it's making it hard.

Guess what? The watch works GREAT!
Color: Brown/Green/Tan
My previous problems with Timex were due to the thousand year battery, combined with a one or two year watchband. So, I buy a watch and wear it for a year or so till the band breaks, then throw it into a drawer and get another. At one time I had four good running watches with junk bands, in my catch all box, in the basement. One was over ten years old and still ticking merrily along! I don't get it! Is Planned Obsolescence becoming the rule of law in worldwide manufacturing organizations? Can't Timex come up with a better class of watchbands, that could match the longevity of their excellent little timekeepers? Maybe! Yes, maybe they have finally done it. My new watch has a band that is made of some kind of nylon, reinforced with, what looks like rutabaga skins, that pretty much insures that the band will last as long as the little ticking machine! Out of the box, the band was remarkably stiff. I had to bend and twist it a lot to make it pliable enough to wear. Then I had a heck of a time trying to get it safely into the band keeper! So I got a scissor and cut a little fabric off the corners on the end of the band. I figured...if the cut off parts start to fray, I can just melt them with some fire and I will be ready for another adventurous expedition to the wilds of adolph's pub! I also noticed that the watch was guaranteed waterproof down to 330 feet. I'll just take their word for that cuz there's no way in hades, I'll let anyone talk me into a trip that far south in a bunch of water! And even if the occasion did present itself, the LAST I would be worrying about, is what time it is! You know? Anyways, now that I have the watch customized to me, I am truly happy! It works well, looks Great and smells like a watch. Yup! I can recommend this gadget to anyone. Stay out of the water though! You never know what may be lurking over there behind that tree! :)

Look elsewhere
Color: Brown/Green/Tan
I have had the identical model watch for almost 20 years. Much like many of the other reviews, the crown fell off when resetting the time to a new time zone. I guess the watch was made a bit more sturdy decades ago and something about the manufacturing process changed. My watch is not easily fixable because the stem itself broke and cannot be repaired; it would need a new stem and crown since the end of the stem is still stuck in the crown. My previous watch kept great time and I found it was relatively easy to program. Because the watch was reliable for so long, I bought another even though it now costs twice as much. The new one was not functional when it arrived. The box the watch came it was damaged because it was sent in an amazon envelope rather than the small Amazon mailing box, although the watch itself seemed fine even though it was dead. I thought it no problem as I have changed the battery a few times on the old watch - the case was held on by four small Phillips head screws. Unfortunately, Timex changed their design and now the case is fastened by far less common triangle head screws. I have precision Phillips screwdrivers for several electronic devices but have nothing with triangle head screws. Of course the one screwdriver that will fit those screws is not sold independently - it is sold in a kit with several other sizes. So, I would have to buy a largely useless kit for the one screwdriver that I would use about every 4-5 years. Timex customer support was responsive but not helpful. Their solutions were to send the watch back to Timex for warranty work which may have taken months as the rep stated it would be sent out of the country, or to go to a local watch repair/jeweler and likely incur a labor charge for a watch that didn't work upon arrival. Based on other reviews, I'd say build quality and the quality control have declined over the years. Be advised; that is what you may be in for if you choose this watch.

Great for protecting my maps
Size: Regular - 12 x 16 Inches
Fits my exploring maps just right. Heavier duty than expected. Ziplock closure is tight and should last for years.
