CUSTOMER REVIEWS
Customer Reviews
I am satisfied with this battery and I was surprised that by discharging and charging it I obtained a capacity greater than that indicated on the label, 266 w/h. I do not recommend discharging it below 11.5 V, this is so that you can have it for a long time and it will function within normal parameters. I recommend this type of battery with confidence. And the order came quite quickly and I recommend the seller.
Very impressed with how compact this battery is. I use it for portable radio equipment and emergency backup. No maintenance required and much safer than traditional lead-acid batteries.
