Bose:*battery is also user replaceable*comes with a "charging base"

how well the battery has held up, and how durable it has been

Solid build, great tone control, impressive battery life and most importantly, surprising sound.

I like all the marshall Bluetooth amps, the Kilburn has the advantage of having an internal battery that has an impressive life.

Good battery life.

It is the best value due to its superior sound quality, quality build and materials, good battery life, and tone

Sounds great, battery lasts all day, and looks killer...

I don't want to throw away my speaker when the battery fails (and they all do eventually, and some quite quickly according to the reviews), so a replaceable battery is a critical feature for me.

Best battery I've seen in a portable speaker yet

Also pretty good battery life.

Plays loud & clear and has tone controls and superior battery life!!!!!!!!

Great quality, great battery life, great portability, & a great overall value.

Zero, no energy use, no chance for unattended exploding batteries and fires

Looks cool, solid construction, loud yet clear, great battery life, and picks up Alexa easily.

Plenty of sound for entertaining in my apartment and with its portability and great battery life, I plan to use it out on the deck too

Looks cool, solid construction, loud yet clear, great battery life, and picks up Alexa easily.

If your battery fails during the warranty period I'm sure Marshall will look after you somehow, but what happens after that???.

(auto reconnects BT when switched on)Compact yet sturdy designLong battery lifePremium quality design (fit and finish)Cons

They have horrible battery inside this thing

Battery never worked from day one.

Best choice for portable sound, best sound, best battery.

Clarity is excellent, battery back up is good.

Battery life very good

I've heard a fair amount of people talking about a failing battery with little use or other issues

Usually takes a couple of hours when the battery is completely depleted.

Sounds good, easy to use/connect, aesthetic (if you like the rock attitude), great battery, room to room portable, analog interface, and apparent quality.

After minimal usage for less than 6 months the battery is dead

I love this speaker, it has great battery life and you can plug in or use Bluetooth

but the battery is still going strong with no sign of getting weaker yet

I had mine 3 months before the battery went bad and wouldn’t hold a charge

What it does have is great sound quality, great build quality and a solid battery-life.

If battery is as good as everyone says it makes this the most un beatable on market

Given that so many Bluetooth speakers have difficult to replace batteries, making them virtually disposable after a couple of years, it's nice that this battery is replaceable

Eventually the battery started Failing, which caused the overall device to fail to work at all

Battery failed after 2 months initially it would Last about 12 hours, now 45 minutes is a stretch, not as loud as my 40 dollar Sharper Image bluetooth speaker and though the battery only last 6 hours, I've had it since December and it's still going.

The bottom line is - it plays well, clean and crisp, never came unpaired and the battery function well

Excellent sound quality, intelligent control panel, good battery, descent range on bluetooth and it looks great.

Good new is, it still functions when the battery is dead and is plugged in to charge.

Impressive battery life.

long lasting battery - INCREDIBLE sound.

So it would make sense if the battery is no longer responsive that to honor their warranty they would have you send back the battery for a replacement.....but that would make to much sense, they expect you to pay for shipping the entire 15lb speaker to a 3rd party for repair
