Spare 7.2V 450mAh Ni-MH Rechargable Micro Battery for MP7 / R4 Series Airsoft AEP AEG

"Will not fit both a TM mp7 and glock. This is ment for the R2/VZ61 and the mp7/r4. this one is actuly slightly bigger the TM g18c aep battery. but over all this is a great replacement battery. ill take one of these anyday

"This battery is great my friends and I use it in both a TM Glock 18c(which actually included this not a TM over-priced pile of... yeah) and a TM MP7 that came with a TM over-priced pile of crap. This lasts twice as long and then some(about 3x really in the mp7) and is only half of what the TMs go for. It's ni-mh which means you can recharge from any mah remaining so if you need a spare, save your money and get one of these and keep the $20 for something else or another one versus the TM ones that are just glorified, re-tagged with the TM logo of these. Ah, and they only take about 2-3 hours to charge depending on how dead it is, so charging one and using the other half-sparingly can quite litterally keep you running one dry while the other finishes charging full.
