I don't have a manual for the ProTime 3 (you can probably find it at the ITC website), but I'm pretty certain that it's using NiCad batteries -- and these are supposed to be good for up to 1000 charge/discharge cycles. (I'm pretty sure they're NiCad because they take a lot longer to charge than LiIon and LiIon batteries are probably too new). I'm adding this in after I posted my speculation on the batteries -- this new meter (ProTime3) uses NiMh (Nickel MetalHydride) batteries, which hold a charge pretty well, have a pretty long lifespan and aren't subject to the 'memory effect' that NiCd batteries had). Depending on how many tests you took, 4-6 months between recharges doesn't sound unreasonable. (If you had a meter that uses disposable alkaline batteries, I don't think they would have lasted TOO MUCH longer). As long as the rechargable batteries held a charge, are almost fully discharged between charges, and are fully recharged before you use them again, they should last for many, many years (especially if you only have to recharge every 4 months).
The ProTime that I bought for 99 cents appears to have last been used in 2004, but once charged, it seemed to hold the charge - even after being dead for who knows how long?
One of the reasons I 'upgraded' to the ProTime 3 was that I'm confident that, if necessary, I could probably make a new battery pack using standard NiCad batteries and the connectors already on the current battery, and save myself a lot of money -- but I'm hoping never to have to do that. (The ProTime meter uses 15 Volts - the battery probably uses 12 or so batteries)
