Genuine /\/\ or not . . .
I have numerous Jedi series portables (HT1000, MTS2000, MTX9000, MTX838). Years ago I used to buy only genuine Motorola batteries but after trying some of the after-market brands I was impressed and began buying them regularly when needed.
I only use my Motorola gear for amateur radio purposes. However, If it were for any kind of emergency services then things would likely be very different. Still, I understand there are some excellent quality after-market batteries available today - it's just that I have no need for higher-dollar Motorola batteries so I can easily get away with a twenty-dollar equivalent
Like others here, I too have been somewhat successful in bringing some batteries back to life after "conditioning" them. I have one of those single battery conditioners I pickled up years ago and it works great. I am able to recondition batteries roughly 50% of the time and get up to an additional YEAR worth of service out of a previously discarded battery, so I also agree with others when it comes to investing in a good quality battery conditioner for your HT1000 batteries. It's clear you would be able to keep a certain percentage of your batteries in service much longer than they do now, thus saving money on overall battery purchases.
There are people who stick their radio in the charger every ten minutes. And there are those who leave them IN the charger most of the day. Then there's the people who leave their HT1000 portable stuck in an MTVA all day and night. All that relates to killing a perfectly good battery in no time but most of the time it can be brought back to life if properly reconditioned
