    This is the second one of these that I have purchased for use in my experimental homebuilt airplane. The originally intended battery which retails for $100+ more than this one is the PC-680. This is a drop in replacement for the PC-680. Has never failed to briskly start my Lycoming 4 cylinder 180 HP engine. I have dual alternators installed so once the engine is running I don’t really care what happens to the battery. If I only had one alternator and needed to rely on the battery for back up power if that single alternator ever failed, well then I might find value in spending 3x’s the price for a battery with a better pedigree. At this price it makes sense to simply replace the battery every year or 2 before the performance starts to get soft, I always have an almost new battery installed.

    This was the exact part number of the battery in my Troy-Bilt generator but the positive and negative were switched I had to put new cables on the generator to make it work I cannot rate the longevity because I’ve only had it a couple of weeks

    I like the top screw down post so I only have to use a screwdriver to attach terminals. It is much easier than attaching with a bolt and nut.

Based on 5010 reviews
When I picked up the battery from the Lowes locker, it had me concerned because of how the packaging looked. Upon further inspection the battery was unharmed in the inner box. Poor presentation on whomever packed it for pick up. All in all, the battery was ok and I'm satisfied.
Easy peasy to replace battery
Perfect fit!
Bike started right up and runs better than it did before!
so excited to try our new trolling motor and the tiniest battery designed for this ever!!! always been such a heavy part of the inflatable, but no more!!!
Harbor freight 3 in 1 jump pack battery replacement.

The process couldn't have been any easier. I went to Amazon and searched on "harbor freight 3in1 jump pack replacement battery">compared and confirmed the battery rating on the back of the pack, then scoured the reviews to be sure this was the correct one>ordered the two pack option for the lower price>box arrived two days later with everything perfectly packed, as a matter of fact beyond perfectly packed>place to pack Bayside down on the cardboard box that the batteries came in (it was simply just convenient like that)>listened the 12 #2 Phillips screws>lifted the back case off and moved it to the side (there's one wire still connected to the back of the case which is for the plug. There's plenty of slacks so you don't have to be concerned about hurting anything)>remove the two bolts holding everything together>remove the battery>put the new one right back in place>place the rear cover back on, drop the screws in, and snug them down>press the test button on the pack, and it came up green>plug the pack in to charge the battery>tested the jump pack on a car and it works brilliantly!

The process could have been simpler or easier to do. If you have a harbor freight jump pack that needs a new battery, save yourself some money and do it yourself, don't take the pack into harbor freight to swap it out or junk it and buy a new one, you could do this with blindfolds on 👍🏼
Easy to order and fast delivery once the unit was taken apart for identification. About half the cost of a new unit.
warranty extension review
Battery came fully charged 12.82 Volts, 214 CCA(higher than advertised). Put in my 1981 Honda 650CB and it fired right up. Great product and price. Will see how it holds up over time.
Price and delivery was great! Hope the battery holds up and if so I will continue to buy again. Packaging was good when delivered and only took 2 days to get. I needed 2 batteries so I saved lots of money. Battery from battery plus only lasted 1 year and 2 months.
7/26 ordered and additional battery now for my waverunner.
So far so good. Got here from Lowe's 5 days sooner than expected. Installing in my ion tailgater.
