MMG YT9A-4 Gel Cell Powersports Battery, Factory Sealed, High Performance Powersports, Compatible with YB9-B, YT9A-BS, 12N9-AB, YT9A

Looked locally for a replacement battery for my 1979 Triumph Bonneville motorcycle and found a lot of overpriced batteries on the market. I went to a local motorsports dealer who handles lots of bikes and he tried to sell me an "obsolete" lead/acid battery for $85 and an additional $15 to fill it with acid and activate it.I found this modern gel-cell battery, ready to drop it in the bike, for less than half the price. Gave it a quick overnight trickle charge just to bring it up to top performance, installed it in my bike and am totally happy with the results.This is the way to go if you need a new battery for your bike!

Great replacement for my Aprilia scooter. My scooter came with a non sealed battery. I didn’t really like the design of that and was at the end if it’s life. This replacement battery is sealed and has plenty of power for what I need in it. Wouldn’t hesitate to buy again in the future. It’s a high quality battery.

The posts on the battery are for vertical mounted cables ,but was listed to fit in my 2010 BMW r1200r.. my cables are top mount so I either jury rig some adapters to the top of the battery or send it back and eat the shipping cost.. yea I'm a little ticked off. Part 2 -Ok it’s a year later since my review and the battery is junk. Will not by this battery or buy from power sport depot again. They both suck!

I bought this to replace a bad battery in my kids Chinese go kart. It is a perfect fit but arrived with the battery terminals bent and distorted. Tried to straighten and make the bolt holes round again which split the positive terminal and made connection uncertain. Have contacted the seller and we'll see where this goes...Update - ordered another battery to replace the damaged unit and after vendor saw photos of the damaged battery, they refunded my money. Second battery arrived in perfect condition and charged. Now a happy customer!

received at 12.4 volts, one week later without being installed tested 11.2 volts. Charged per manufacturers instructions-would only charge to 11.9 volts. Had battery tested at the auto parts store and was told it had a dead cell. Returned to seller and had to pay $14.35 shipping to get a refund for their defective battery. JUNK !!!

The battery lasted about a year before it died and could no longer hold a charge.

Great battery for the price, my only problem with it is the posts. They are flat and they don't have anything to house the backing nuts. It's minor.

Perfect for what I needed it for.
