GTMax 1800mAh Standard Lithium-Ion Battery for HTC Verizon ThunderBolt GTMax 1800mAh Standard Lithium-Ion Battery for HTC Verizon ThunderBolt

Pros: Still holds a charge. Really cheap.

Cons: Battery life has lessened over time.

Other Thoughts: I previously rated this battery at 5 eggs but I knocked off 2 because the life has degraded over time. I get about 70%-80% of the stock battery life. I still use it as a backup battery so it's still useful to me and you cant beat the price.

Pros: Didn't damage the device. Didn't require a doublethick backplate.

Cons: 80% the life of the stock 1400 mah battery the device shipped with.

Other Thoughts: This is as apples to apples as a comparison gets. Same hardware, same ROM, same apps, same config, same use pattern. For 10 bucks I should've known it was too good to be true.

Pros: None

Cons: Runs down faster than the factory battery. Not worth the money and it would cost me more to ship it back so I will probably just throw it away.

Pros: Lasts longer than stock battery, same size so you dont need a new backplate.

Cons: None so far.

Other Thoughts: I got this battery since it was the cheapest one I could find. My dock that I have has a spare battery charger on it so I thought it would be nice to be able to charge one at work so I always have one ready. I didnt think I would notice a battery life difference, but I would say that this battery is at 40% when the stock battery is at 10% with similar time/usage. Have yet to see if the battery life tapers off.
