Fitted to a customised honda GL 500. it is small enough to fit under the seat and very light .

Had to change the regulator to a mosfet to be compatible with the Li ion.

It is as described very small and very light

Good product, one detail only

Very good leadtime, nice packaging, good product as expected.
Only comment is on the wiring ports that comes with two screws but no blocking features.
Either a male thread (that you can connect with nylon nuts ) or a special washer would make the connection safe, as this is for aircraft application.

AG801 Battery & Charger
Monday, 1 February 2016  | 

I had been looking to find a better battery for my Honda cb400ss as the oem one was small and it didn't have enough power to start the bike in the winter. After much trawling of the internet I liked what Antigravity batteries claimed for their products. After emailing the sales team, measuring the old battery and taking advice from my local mechanic I ordered the AG801 battery and charger to go with it.
The box arrived on the Monday when it should so no complaints there, however, because the nights are still gloomy when I get home from work I had to wait until Saturday to install.
Saturday finally arrived and the weather was kind in the afternoon so after a mornings shopping with SWMBO I put some old warm clothes on and got to work.
I took the old battery out and as the cable connections were different a trip to Maplins was required to get the correct conectors.
I wired it all together and used some packing foam to make it snug in the tray and now the great switch on.
Well to say I was dissapointed was a bit of an understatement as the bike refused to fire up despite 4 or 5 attempts. So I left it for a while and SHMBO suggested trying to kickstart it so out I went again and turned it over manually 5 or 6 times (those were the days!!) then I pressed the starter and it burst into life.
Left it running for half an hour or so while I sorted out the charger. Unfortunately it hadn't come with all the leads but that wasn't a problem as I had emailed Paul at Antigravity on Tuesday and he put a lead in the post so all was well. After a bit of jiggery pokery I got the charger system how I wanted it and left the bike on charge overnight.
On Sunday morning went out and disconnected the charger, pressed the starter and 2 seconds later the bike roared into life (which was a lot quicker than the old battery on a good day!!) So, success at last as it wasn't so much the weight saving I was after as the actual starting process being quicker, consistent and reliable. I suppose the original starting sequence on Saturday may have been hampered by the fact that - the bike hadn't been started for a while and the battery straight out of the box may not have been fully charged.
Anyway, I have now left it on chage so at the weekend I will start it up again and see if there are any problems.
So, from my experience this weekend and the service I have had from Antigravity I would definately give the company and product 5 stars as hopefully the battery lives up to my expectations and takes the worry out of will it won't it start when I start using it to commute to work in 2 or 3 months time.
Would I recommend to a friend yes definately, however, I think the cost may put some people off (32 for a replacement oem battery as opposed to 180 for this one) ,however, you get what you pay for and if the worry is taken away then as far as I am concerned it is worth the money.

Bike: CBR600RR 2007
I bought this battery for weight savings on a bike that see 365 days a year use on the street.

It's so light that, at first, you wonder if they forgot to put the battery in the box. I had removed the old battery the night before and though this would simply be a drop in replacement but its smaller than i could have imagined. After 20 minutes of pondering and trying out various orientations, I plucked up the courage to rip the adhesive backing off the included foam padding and set to work cramming the little battery into the gaping void that was designed for the old lead acid one.

The redesign for the 2007 CBR centralises the mass at the centre of the bike with numerous other weight saving differences over its predecessors so with this in mind I tried to have the new battery as close to the left of the battery box with the spacer foam padding out the right hand side (assuming you working from the clutch side of the motorcycle).

Next step was to work the terminals - they are sunken in which meant the tabs on the connectors for the live and earth needed bent out a little. They secure into the terminals easily after just a few millimetres of bending with the supplied screws.

Excited I wire the bike back up, turn the key and thumb the starter. The bike rips into life and I'm left with a stupid grin. Stupidly I accidentally flooded the engine by killing it too quick after the first start which led to me thinking the battery was broken after numerous failed start attempts - All I needed to do was start her up with the throttle wide open - the battery was fine.

Move forward to day to day use, the bike starts up just as quick as it did with the old 3.2KG lump so no issues there... The change in handling is immense and that was what I was looking for, the bike feels much more flickable due to the big loss of weight right at the centre of gravity and it really does show.
Having come from KTM bikes I find other brands a bit portly so this was a noticeable and worthwhile upgrade.
Very pleased - and with the three year warranty I have lots of confidence that it should last.
