ANSAI Rechargable 7.4-Volt Lithium-Ion Battery (2.2Ah)

Have to recharge after 1 hour although it is claimed to last for 2 hours. Besides this it works ok.

I think its a Good buy, but doesn't hold charge near as well as the slightly more expensive Gensinger Battery.

So far it works great.

I ordered this extra battery when I ordered a battery heated vest at the same time. But the vest was backordered so I had no need for the battery and returned it.

One of the two I purchased stopped working within a week. Same story with other brands I have tried. Now one of the gloves stopped working too. Nice idea not matched by products.

After charging battery twice after using. The third time I attempted to the battery it would not charge completely. I like the heated vest but if the batteries are going to fail so quickly the vest I purchased is useless.

I wish it lasted longer. I have an extra but they're heavy.

Works great
