Title: Don't get your hopes up
Product review: I've had 4 of these batteries explode in the packaging after about 2 weeks of storage. The ones that survived lasted a total of about 2 minutes in my 7.62x54r Laser boresighter. Being that I only had 6 batteries left, and the laser took 3, I had a total of 4 minutes (give or take) to boresight my rifle at 100 yards. These batteries are alright for the price, but this is one of those rare cases where you really do get what you paid for. If you can find other brands of this type of battery, I would say its worth the extra money to get those instead of these.
Would you say this review depicts the product in a flattering or unflattering light?
