DataSafe NPX-35TFR - 12 Volt/35 Watts per Cell Sealed Lead Acid Battery with 0.250 Connector - Flame Retardant Case

Bought these for my Sears Craftsman 48volt battery operated deck mower. Slip in/Drop in replacement, and replaced all 4, which was very easy for me to do. You need to lift the top of the mower off, slipping a screwdriver in to release the plastic retainer clios- but be careful not to break the wires by yanking the top off too hard. The connector wires are a bit short, so just get it loose and drape it to the side if you can. The four batteries are held in with a zip tie that you can push to one side, and pull out one battery at a time. Just pull the jumper clips and replace the batteries one at a time, and you should have no problems. I took the time to clean out any bits of dust or grass that had gotten in the deck too. Replace the clips, put back on the retainer zip tie, and the top (it snaps back on) and then charge it up. (I charged overnight just to be sure) Before this replacement, I was lucky to do a small part of my front yard before having to recharge. Never got above two green dots even after over night charging. New batteries took it right up to full four green dots, and I was able to cut the front, back and neighbor's yard before it dropped to two dots... and it was very quick to recharge. Great product, and the shipment was quick, the packing was great, and everything works well.

Works great. 2nd time buying.

Battery replaces sears craftsman battery operated lawnmower, The lawnmower batteries needed to be replaced after 3 years, I purchased four batteries and they charge and work great! Also just a note I also replaced the wiring to the batteries, they were showing wear and there was a possibility that the old batteries were not charging correctly, so I would advise if you have a handy person to replace the wiring that charges these batteries.

My Craftsman lawn mower needed four of these lead-acid batteries. If I had gone through Sears, I would have shelled out about $160.00, not including shipping. These batteries are the exact same kind that came originally with the mower and I found them on Amazon for a 1/3 of the price. I just received the batteries today and have the installed and the mower is working great!

Works OK but could last a bit longer before we have to replace them again in our battery powered electric mower

Bought this for my TripLite battery backup. It came charged, fit perfectly, and I was up and running in no time. Sure beats buying a whole new battery backup system!

Very poor performance. My lawnmower operated effectively with 4 OLD (5 years old) batteries for about 20-25 minutes. These NEW batteries operate effectively for no more than 20 to 25 minutes!!!??? When the lawnmower was new it operated effectively for 50 to 60 minutes. I QUESTION whether these batteries are actually new??? If in fact they were new, they are NOT WORTH BUYING!!!
