Query: Extremely short battery life.

I ordered the Next Generation remote extender beacuse of the generally good reviews. My experience withthe product didn't match most of the purchasers.My Direct Tv remote normally uses 2 AA batteries. When one of the AA batteries is replaced withthe 2/3 AAA nicad supplied, the battery life was reduced to less than two days. In fact the nicad in useexpired before the spare battery was recharged. I went through 3 recharging cycles without anyimprovement in life span.I suspect that if your remote uses 4 batteries, the battery life will be extended to acceptablelevels, then too the Direct TV remote might be more demanding on the battery.At least one of the reviews that gave a low rating to the product mentioned low battery life.(The Next Generation was tried in two DirectTV remotes with same results).hilcntry
